After More Than a Decade and Thousands of Disfiguring Injuries, Power Tool Industry Still Resisting Safety Fix

They crowded in for the hot dog show.

An Oscar Meyer wiener, serving as proxy for a finger, was pushed into the spinning blade of a table saw. The demonstration, at the International Woodworkers Fair in Atlanta, mimicked the way gruesome table saw injuries often occur. But this saw was equipped with a safety device called SawStop that allowed the blade to distinguish between wood and flesh, and to stop fast enough to prevent serious harm. Sure enough, the blade came to a dead stop in about three one-thousandths of a second, leaving the dog with only a minor nick.

Table saw accidents are painful, life-changing and expensive. Each year, more than 67,000 U.S. workers and do-it-yourselfers suffer blade contact injuries, according to government estimates, including more than 33,000 injuries treated in emergency rooms and 4,000 amputations. 

Gerald Wheeler had other numbers on his mind as he watched hot dog meet blade that day in August, 2002. As the operator of a wood shop in Hot Springs, Ark., Wheeler was all too aware of the unforgiving nature of table saws. Not long before, two of his employees had been maimed within a few weeks of each other. Wheeler felt awful about the injuries, the loss of two good workers, the $95,000 in medical bills, the doubling of his workers compensation rates.

Wheeler thought: If only this had come along sooner. He took out his Visa card to order two of the saws, but was told none were available. As the SawStop guys explained, they had been seeking licensing deals with the big power tool makers, but had found no takers.

Faced with the prospect of never getting the invention to market, the little company, also known as SawStop, eventually started making its own saws. Since the first went on sale in 2004, SawStop says it has recorded 2,000 “finger saves”—customer reports of  accidents likely to have caused disfiguring injuries with conventional saws, but that resulted in minor cuts or a few stitches at most (SawStop also acknowledges two reports of amputations.).

“Bravo!” a man named Frank Oslick emailed SawStop, explaining that he had lost two fingers and part of his thumb in a table saw accident when he was 14. “I have not lived a single day without regretting that accident,” he wrote. “If your device prevents even one person from going through what I have gone through it is a world class accomplishment.”

The hot dog demonstration

However, SawStop still makes the only saws with skin-sensing technology, and accounts for a tiny fraction of sales. Tens of thousands of fingers have been sliced off since the system was invented, but the rest of the industry, which is self-regulating, has been allowed to go on as before.

Over the years, top saw makers and the Power Tool Institute, their trade group, have defended the design of their saws and the decision to snub SawStop.

They’ve argued that injury numbers have been inflated and that the government’s estimate of $2.36 billion in annual costs to society from table saw accidents—including medical bills, lost wages, pain and suffering—is exaggerated. They say the market for popular, lightweight saws costing as little as $100 would be destroyed by the added expense of SawStop. They note that under some circumstances, SawStop can stop a blade without skin contact–such as when the blade touches conductive materials like metal or very wet wood. In such cases, the owner usually has to replace the blade and an electronic cartridge.

But as court records and testimony have shown, the companies rejected the safety advance for another reason, too: They worried that if a way to prevent severe injuries got traction in the market, they would face liability for accidents with conventional saws.

Even so, they have had to defend lawsuits. About 150 have been filed in recent years, focusing on the companies’ decision not to use available safety technology.

The industry is also trying to keep the Consumer Product Safety Commission from requiring injury reduction systems on all table saws—either SawStop or something similar. Indeed, another firm, Massachusetts-based Whirlwind Tool Co., says it has developed a “proximity detection” systems that will shut down a saw when a hand comes close to the blade.

“Within a second my fingers were on the ground.” — Tom CorbettListen to his story:
By Lilly Fowler

Tom Corbett was helping remodel the front entryway of a home in Manchester, Mass., two years ago when suddenly his life changed forever.

A piece of wood he was trying to cut jammed in his table saw, and his hand was thrown into the blade. He still struggles to remember all of the horrible details, but he’s haunted by the fact that four of his fingers were severed. “I just know within a second my fingers were on the ground,” he said.

That’s how Corbett became one of the thousands of Americans suffering amputations or other serious injuries in table saw accidents every year. Read more.

But the industry may have little to fear from the commission. The agency has been wrestling with the issue, on and off, for 15 years. So far, its most definitive act has been to give SawStop an award for safety innovation. It will be at least next year before the agency adopts a regulation, if it ever does.

The SawStop story is about an industry’s ability to resist a major safety advance that could, by now, have prevented countless disfiguring injuries, but might have been bad for business. It highlights the endless due process that makes it virtually impossible for regulators to enact safety measures over the unified objections of industry.

It’s also something of a David-and-Goliath story–though in this case David, rather than carry a sling, is armed to the teeth with patents.

Several industry representatives declined interview requests or did not return calls and emails seeking comment. The Robert Bosch Tool Corp. provided a statement: “Safety has historically been one of the Bosch principles…and is reflected in our slogan ‘Invented for life.’”

Birth of SawStop

Stephen Gass is energetic and intense, a trimly built man of 49 whose home near Portland, Ore, is a manageable drive from some of his favorite whitewater kayaking runs. He grew up on a horse farm in Eastern Oregon, and was taught woodworking by his father. He earned a doctorate in physics and a law degree, then joined a patent law firm in Portland, but retained his interest in building things.

Gass created an elaborate workshop behind his house. For some reason, while out there on a fall day in 1999 he was struck by a question: Would it be possible to stop a saw blade quickly enough to keep it from slicing off your fingers? After a series of calculations and with parts you could buy at Radio Shack, he showed it could be done.

The invention involves running a weak electrical current through the saw blade. When a person comes in contact with the blade, the body absorbs part of the signal. An electronic sensor detects the change in current and activates a spring. The spring jams an aluminum wedge between the teeth of the blade, which acts as a brake. The blade also drops below the surface of the table. It all happens in so few milliseconds that, unless the hand is moving unusually fast when it hits the blade, the injury typically is minor.

One of the mysteries is why the power tool industry, with its engineering prowess, didn’t invent SawStop before Gass did.  Maybe he was smarter. Or maybe the industry didn’t do it because it didn’t need to.

There were no clear financial or legal incentives. Table saws are a must-have tool for millions of construction workers, cabinet makers and do-it-yourselfers. In the U.S., there are about 9.5 million of them in use, according to industry figures. Of about 500,000 sold each year, 85 percent are supplied by members of the Cleveland-based Power Tool Institute, including such well-known brands as Black & Decker, DeWalt, Makita, Skil, Bosch and Ryobi.

For decades, the companies were shielded from liability by a few unquestioned assumptions: Namely, that table saws were inherently dangerous; that everyone knew this; that accidents typically involved carelessness or failure to follow directions; therefore, when people got hurt it was their own fault. As an industry lawyer told a jury: “This is a table saw. It cuts wood. And if you’re not careful, you can get injured.”

Emotionally and financially, “it’s devastating.”–Adam Thull

Listen to his story:


By Lilly Fowler

Adam Thull was building a checkout counter for a local bookstore when he noticed a wood panel falling off the edge of his table. As he lunged to catch it, his right forearm got caught on the blade of his Ryobi table saw – and the machine quickly cut completely through one of his forearm bones and a nerve.

Thull, 32, who was working at his shop at home in the small community of Crosslake, Minn., was airlifted to a hospital. That was the beginning of a medical odyssey that has included seven surgeries and visits to a specialist at the Mayo Clinic in Rochester, Minn., more than 200 miles away. Read more.

Saw designs are governed by a voluntary standard worked out between an industry-dominated technical committee and Underwriters Laboratories. When SawStop came along, the voluntary standard called for a guard that fit like a hood over the blade. Because a hand can slip under the guard, many thousands of injuries occurred even with the guard in place. Usually, however, the guard wasn’t being used. Because it limited visibility, had to be removed for certain cuts, and took a long time to detach and put on again, most people worked without it. Critics said the guard did more to protect the manufacturers than users.

In a letter to Underwriters Laboratory in April, 1998, an engineer for the CPSC linked the high injury toll to poor design of the guard. Said the engineer, Caroleene Paul:  “Experienced saw users comment that ‘the typical stock guard that comes with many saws is so frustrating to mount, align, adjust, remove and work with, you’re tempted to leave it off permanently.”

Members of the Power Tool Institute insisted there was nothing wrong with the guard. Following a December, 1999 meeting, Paul summarized their position: “Education is the only way to affect the injury hazard patterns seen. Education, not redesigning the guard, is needed to convince the operators to use the blade guard.” The institute pledged to do its bit by making a video.

SawStop wrecked this way of thinking. Saw makers now had the ability to prevent the tragedies they knew were going to happen, that had always happened. For this reason, Gass thought, his invention should be an easy sell.

“I couldn’t imagine that anyone would not want to put this on the saws that they were offering to people,” he said.

He recruited three friends from the law firm, all named David, to put up seed money for the new venture. The industry’s initial reaction was not encouraging. Gass recalled being told by one executive: “The marketing guys say safety doesn’t sell.”

Hoping to stir grass-roots interest, Gass and the Davids made their first trip to the woodworkers fair in August, 2000. They were sent to the nosebleed section—a tiny booth in a conference room on the third floor of the Atlanta Convention Center. But as word of the hot dog demonstration spread through the fair, they were soon drawing crowds. SawStop was awarded a top prize for technological advancement.

Saw makers also took notice and issued invitations. Soon Gass and his partners were visiting corporate offices of Emerson Electric; Black & Decker (now Stanley Black & Decker), Ryobi and Bosch. In November, 2000, they briefed members of the Power Tool Institute in Cleveland.

The companies seemed intrigued but wary. SawStop vice president David Fanning recalled being asked at Ryobi and Black & Decker: “Have you been to the CPSC? Our response was: ‘What’s the CPSC? ‘ ” Gass said a Black & Decker executive also warned: “If you guys don’t cooperate with us, the industry is going to get together and squish you.”

Still, the SawStop men were stoked, maybe even cocky. “We think you don’t have any choice here,” Gass said he told an executive of one company: “It’s the right thing to do. And if you don’t do it, you’re going to be liable for the injuries—and there’s a lot of injuries happening.”

Their prospects seemed to rise when CPSC engineers, in July, 2001, announced the results of a technical evaluation. “The SawStop concept is valid and the prototype impressively demonstrates its feasibility.” Ann Brown, then head of the agency, awarded SawStop a Chairman’s Commendation for safety innovation.

Negotiations were held with several companies. Talks with Ryobi advanced farthest, then collapsed under mysterious circumstances.

A leading manufacturer and supplier to Home Depot, Ryobi is based in Anderson, S.C., and is a subsidiary of Techtronics, Inc. of Hong Kong.

In January, 2002, Ryobi sent SawStop a signed licensing agreement. It called for Ryobi to investigate SawStop’s feasibility, and to incorporate it in Ryobi saws within 18 months if it proved feasible.  SawStop would get a royalty equal to 3 percent of the wholesale cost of each saw, with the fee rising as high as 8 percent should the technology be widely adopted.

Gass said a small typo led him to return the contract to Ryobi’s general counsel, who Gass said told him he would immediately fix the mistake and mail the contract back. Days turned into weeks, then months. Gass said he got repeated assurances that Ryobi wanted to proceed, but the contract never came back.

Years later, in the trial of a lawsuit against Ryobi, a company lawyer explained it this way: “Ryobi decided that it did not want to go forward with this project,” he said. Ryobi was going through a corporate acquisition, the SawStop deal took “a back seat”, and “eventually Ryobi lost interest.”

Robert Bugos, the former general counsel Gass said had strung him along, put it another way in a deposition. “There was negotiation back and forth,” Bugos said. “Our position was always that SawStop was asking too much.”

Lawsuit Worries

However, testimony and documents reveal the industry also feared liability exposure should SawStop gain a foothold. According to testimony by David Peot, Ryobi’s former director of advanced technologies: “There certainly was a feeling that if a single company invents or improves a product that could have an effect on product liability, then other manufacturers could be at a disadvantage if they don’t have that on their product.”

“What the industry saw as a problem was not the amputations and injuries occurring on their product, but the advent of a technology that could prevent those injuries. That was the problem we created.”

    – Stephen Gass, inventor of SawStop

Without naming SawStop, an April, 2002 Bosch memo warned of the threat from “competitive technology.”  The “expectation will be that the most severe injuries will be mild to moderate lacerations and that amputations will be virtually eliminated,” it said. This “will create a new and significant liability concern for our corporation because of this enhanced safety performance.”

Or, as minutes of the Power Tool Institute’s product liability committee put it: “Liability exposure has increased based on the product’s introduction at IWF [International Woodworkers Fair].”

Gass recalled being told by Peter Domeny, then chairman of the committee and Bosch’s director of product safety, that SawStop had kept him awake nights wondering how the industry could defend itself in court. Domeny was questioned about this in 2008, when his deposition was taken in the case of a Pennsylvania man who suffered the amputation of four fingers.

“We had discussions as far as the liability implication, but not in that form as he [Gass] quotes it,” Domeny replied. “I don’t think I have discussed my sleep patterns with Mr. Gass.” Domeny declined to be interviewed.

Gass said he came to realize the threat his invention posed. “What the industry saw as a problem was not the amputations and injuries occurring on their product,” he said, “but the advent of a technology that could prevent those injuries. That was the problem we created.”

Early on, Gass and two of the Davids had quit the law firm to give full time to SawStop. Having failed to license the technology, they faced a stark choice: Either go back to patent law and let the invention die, or find the capital to make their own saws. They chose the latter, Gass said, and raised $3 million from about 30 investors.

The industry response was unprecedented. Five companies, including Black & Decker, Bosch and Ryobi, formed a joint venture to develop their own injury reduction system. To head off possible anti-trust problems, they told the Justice Department and Federal Trade Commission what they were doing. Their notice said they would pursue “research and development of technology for power saw blade contact injury avoidance, including skin sensing systems, blade braking systems, and/or blade guarding systems.”

Years later, Peot, the former Ryobi executive, still seemed stunned by the move. “The people who belong to the Power Tool Institute are very fierce competitors,” he testified. “Never before in my 30, 35 years of working with the Power Tool Institute had I ever been exposed to something where they said let’s get together and jointly develop something.”

The joint venture ended in 2009, when members said they had developed a system superior to SawStop. It has yet to be incorporated into a single saw.

Their system is designed to retract the blade into the table immediately on skin contact. Unlike SawStop, it does not use a brake, which can damage the blade. Representatives of Ryobi, Black & Decker and Bosch did not return calls about when, or if, the technology will be used. Industry comments filed with the CPSC asserted that SawStop’s patents were holding them back–potentially forcing them to pay royalties or engage in expensive patent litigation to introduce their system.

SawStop, for its part, put its first saws on the market in 2004 and has sold about 40,000 since. Along with flesh-detection technology, the company’s saws came with an important safety device called a riving knife that had been mostly limited to models sold in Europe. A riving knife is a curved steel blade that cuts the risk of “kickback”, which occurs when a piece of wood suddenly jerks while being cut, sometimes pulling the operator’s hand into the blade.

Gerald Wheeler, who had been wowed by the hot dog show, got two of the first saws. In March, 2006, Carl Seymour, a foreman at his shop, accidentally touched a whirring blade. A photo on SawStop’s website shows Seymour beaming in triumph as he lifts the wounded thumb, which looks like it has a paper cut.

“You couldn’t wipe the smile off him (Seymour) after this,” Wheeler told FairWarning, saying he, too, was “totally ecstatic.” All saws should have this technology, Wheeler said. “I mean, we’re dealing with human beings.”

Shot Across the Bow

No longer having anything to lose, SawStop fired another shot. It organized a petition signed by more than 300 woodworkers, shop teachers and others, asking the CPSC to regulate. Filed in April, 2003, it called for a performance standard that would most likely require SawStop or something like it.

Gass told Fairwarning the idea came from Caroleene Paul, the CPSC engineer. Given the commission’s limited resources, Gass said Paul told him, the agency would be more likely to investigate the issue if petitioned to do so. (A commission spokesman confirmed this account.)

“There can be little question that Mr. Gass and the SawStop company primarily are motivated by their own monetary gain, rather than purely to improve public safety.”

    – Power Tool Institute, in comments filed with the Consumer Product Safety Commission

In July, 2006, commissioners voted 2-1 to instruct their staff to draft a document starting the rulemaking process. Called an Advanced Notice of Proposed Rulemaking, it would have been published in the Federal Register with a request for public comments.

Then things took a bizarre turn. Within days of the vote, commission Chairman Hal Stratton, who had voted yes, resigned to join a law firm. The resulting 1-1 stalemate meant the rulemaking notice could not be approved. This was during the Bush administration, which was stridently anti-regulation. The commission would go three years before getting a third commissioner and again having a quorum.

Battling in the Courts

Even as the threat of regulation eased, the industry faced trouble in the courts.

Carlos Osorio was a computer technician from Colombia who moved to the Boston area in 2003 to be near his girlfriend. Unable to find work in his field, he took a job as a flooring installer and learned to use a table saw.

He was working at a home in Lexington, Mass., in April, 2005 when a piece of flooring got stuck in the Ryobi saw and Osorio’s hand slid into the blade. “There was blood on my face, my body. It was everywhere,” Osorio testified. “I was able to see my tendons.”

Screaming in pain, Osorio and a co-worker ran into the street and flagged down a motorist, who called 911. The first of five surgeries lasted 12 hours and reattached Osorio’s pinky finger. Another transferred tendons from a toe to his hand in an attempt to restore movement. Osorio said he endured so much pain that one doctor suggested he have two of the injured fingers surgically amputated. Osoriio had 95 physical therapy sessions. His medical bills topped $384,000. Now living in Florida, he still has limited use of his left hand. “The damage that was done to my hand, it’s something that stays with you for the rest of your life,” he said in an interview. “I think the manufacturers should think less about cost, but more about people who are using the saws.”

During the trial of his lawsuit in February, 2010, in federal court in Boston, Osorio admitted he was working without a saw guard, and said guards were not used by others on his crew.

Before SawStop, this fact alone would have made a successful lawsuit unthinkable. But Gass testified about his efforts to license SawStop to Ryobi and others. He said that Osorio almost certainly would have escaped serious injury had SawStop or another skin-detection system been in use. The jury awarded damages of $1.5 million.

SawStop was a “game changer,” said Osorio’s attorney Richard Sullivan, whose Wellesley, Mass., firm has been involved in most of the recent cases. The industry position was “ ‘Hey, don’t blame us,’ ” Sullivan said. “Now with Saw Stop it was ‘Oops, we actually can prevent these accidents from taking place.’”

About 70 of the roughly 150 cases have been settled, said Sullivan. Only two, besides Osorio, have been tried. A Los Angeles case last year ended in a hung jury, then was settled. In the other, tried last July in Chicago, Ryobi was victorious.

The plaintiff was Brandon Stollings, who suffered the amputation of two fingers while installing flooring at his mother’s house in Wisconsin in May, 2007. Stollings, then 23, had been captain of his high school basketball team, and had passed on college to pursue his goal of becoming a homebuilder. He testified that after the blade sliced into his hand, he began running around in circles in his mother’s yard, screaming in pain and terror about what had just happened.

“ ‘Am I ever going to be able to do carpentry?’ “ he remembered thinking. “ ‘If I cut off my ring finger, who’s going to want to marry me if I can’t even put a ring on my finger? ‘ ” Lying in the ambulance, he told his mother: “ ‘Just let me die’…because I thought my life was over.”

After nine hours of surgery the ring finger was reattached, but Stollings lost the index finger. Though five years had passed between the accident and his court appearance, Stollings said he remained self-conscious about his hand. “If I’m meeting new people, my hands will be in my pocket,” he said. “I never had this hand really out in the open.”

Stollings, who had years of experience with table saws, testified that he was not using a guard and never did because it got in the way. Gass testified that Stollings would have escaped serious injury if the saw had skin-sensing technology.

“If the manufacturers had to pay the cost of those injuries,” Gass said, “they would have adopted technology like this within months of the time they heard about it instead of looking for excuse after excuse to delay for year after year.”

This time, however, Ryobi’s lawyers shifted the focus from the maiming of a young man to a purported conspiracy between plaintiffs attorneys and Gass—designed to bleed the industry by, in the case of the lawyers, filing lawsuits; and in the case of Gass, forcing manufacturers to adopt SawStop. The jury found Ryobi not liable.

Wall of Patents

SawStop’s headquarters is in the back of a business park in the Portland suburb of Tualatin, next to a marshy field favored by egrets and geese. About 40 employees occupy the hive of offices, workbenches and warehouse space. Saws aren’t actually manufactured here; as with nearly all others sold in the U.S., SawStop’s models are made to its specifications in Taiwan.

Rows of gleaming patents for saw components cover entire walls. Those patents have become an obsession of the industry as it fights to keep the CPSC off its back.

Legislation passed by Congress in 2008 had resuscitated the agency, adding funding and expanding it to five commissioners. Yet the table saw issue stalled. In November, 2010, —the National Consumers League fired off a protest letter to commission chairman Inez Tenenbaum.

“While this…languishes before the Commission, with no action taken by previous CPSC officials, every day ten new amputations associated with the use of table saws occur,” the letter said. “The hazards posed by table saws are unacceptable, especially when we have the means to prevent these accidents.”

The thrust of the letter, said the league’s executive director Sally Greenberg, was “what the heck have you guys been doing over there?”

The league arranged for several injury victims to meet with commissioners. In October, 2011, they voted 5-0 to publish an Advanced Notice of Proposed Rulemaking–the step nearly taken five years earlier.

In the notice, the CPSC pegged the average cost of a table saw injury at $35,000—for a total cost to society of $2.36 billion for the estimated 67,300 injuries per year.

The Power Tool Institute disputed the estimate as highly exaggerated. And in comments with the commission in March, 2012, it said a federal regulation would grant a “monopolistic advantage’’ to SawStop, whose patents might shut out rival safety systems, such as the one developed by the joint venture.

“There can be little question that Mr. Gass and the SawStop company primarily are motivated by their own monetary gain,” the institute declared, “rather than purely to improve public safety.”

Further, the industry reminded the commission of a legal constraint that could block regulation. By law, the commission must defer to voluntary standards that could adequately improve safety. As a result, by revising a voluntary standard, or by simply working on revisions, an industry might be able to forestall regulation indefinitely.

The industry had, in fact, made a couple of changes to its voluntary standard. A 2005 revision provided for use of a riving knife; another in 2007 called for an improved blade guard.

Since late 2007, hundreds of thousands of saws with the new guard had come into the market. Therefore, the industry said, before adopting a regulation the CPSC must investigate the impact of the changes. The agency has agreed to study consumer usage of the new guards.

“This is a serious hazard which has greatly impacted far too many lives,” commission spokesman Scott Wolfson told FairWarning. “This is a rulemaking that can make a difference…if we can reach the final rulemaking stage.”

Ann Brown, who left the chairmanship soon after giving the commendation to SawStop in 2001, told FairWarning she was “shocked” that the issue remains unresolved. “The industry has managed to delay every step of the way.”

Hal Stratton, chairman until 2006, said he was not shocked. “How could I be, after being there and experiencing working at the agency?” he asked. “The way the law is written, there’s a lot of hurdles to get over to get a regulation passed.”

Expecting little from the CPSC, SawStop tried another way to force the issue. Last year, it lobbied the California legislature to pass a bill requiring injury reduction technology for table saws sold in the state. California is such a huge market that companies forced to meet its standard sometimes apply the changes across whole product lines. The bill was defeated, however.

SawStop could make plenty of money if a table saw standard were adopted, but is profitable just selling its saws, according to Gass.

“I feel like I’m doing a good thing,” he said, adding that he would not take “a lot of moral credit.  I’m doing what I also think is in my financial interest.”

    The PTI objects to the licensing necessary due to the “more than 50 patents” related to SawStop’s braking system;[10] such costs “would destroy the market for the cheapest, most popular saws, adding $100 or more to the price of consumer models that typically sell for less than $200.”[8] In response, their members developed “new plastic guards to shield table saw users from the dangers of a spinning blade” and began selling models with that feature in 2007; as of May 2011, PTI says “its member companies have received no reports of injuries on [the 750,000] table saws with the new guard design.”[9]

    hi!

    you left me hanging there?

    so…were the new guard changes successful in reducing injuries the past few years for top-brand saws?

    i think i read somewhere that new guards/etc. have made an incredible difference.

    but, i could be wrong.

    any ideas/facts on this?

    In response to some comments. Read the definition of accident . If one happens to you or your children, you will be singing a different tune.

    I fail to understand this continual push towards the lack of any personal responsibility using products of any sort that may cause personal injury due to a user’s stupidity. Show me an instance where it is not the user’s neglect that caused their injury. Can’t do it can you? Guards are removed, read a comment somewhere else that someone was wearing gloves, etc… The stories shown in this article relating to the injuries ultimately show the lack of regard for ones personal safety, or any respect for the tools involved. If the guard was in place, Adam Thull wouldn’t have been injured. If he had support in place on the piece of wood he was cutting, he wouldn’t have been injured. Tom Corbett claims to be experienced and safety conscious, yet his wood “jams” and his hand is “thrown” into the blade. THAT DOESN’T HAPPEN. Unless of course, you are pushing extremely hard on the wood, and NOT USING A PUSH STICK, something my junior high shop teacher would have lambasted us for and sent to the principle’s office if anyone was caught not using one. One more offense and you would be kicked out of shop class. A bandsaw is far more dangerous than a table saw, due to the proximity of your hand and fingers to the blade, but people are far more careful I guess, since we don’t seem to have tons of lawsuits regarding them. Using common sense, and accepting the shame of personal responsibility for stupid actions has been abrogated by the industry of personal injury lawyers who are more than happy to enrich themselves by showing the world that a lack of intelligence isn’t a barrier to financial success, all you have to do is prove your stupidity by causing bodily injury to yourself or others, and get a jury to blame someone else. That is really sad.

  6. Mike Cambra

    What ever happened to a little personal responsibility? I’ve been using a table saw for years and still have all of my digits. I’ve shown my son what the table saw is capable of also. A healthy fear of the blade is required to use it.

    I don’t blame the industry for not implementing it. If you want to have the device then go buy a saw with it installed and leave the rest of us and our tools alone.

  7. Skip Couture

    Nowhere in this article did I read what it would cost to install saw stop. What is the cost for a manufacturer to have saw stop on it’s saws???? I somehow cannot believe it would be that expensive. Is there damage to the saw when and if this system activates???? If damage does happen, what is the cost to repair the saw????
    Why are these and I am sure many others not answered or even brought up????

    Many thanks to Myron Levin and Lilly Fowler and FairWarning for this insightful piece on the SawStop saw, and it’s safety features. I had the good fortune of using a SawStop cabinet saw for the last several years in our university wood shop, thanks to an insightful engineer friend in management who had seen a demonstration of the saw, and thought that an aging long-term employee deserved good equipment. The SawStop saw was easily the best built table saw in our large shop, and the only time I used the larger Delta saws (5hp), was to break down sheet goods, or to do repetitive rips of hardwoods using an automated feeder. The saw works as advertised, and when I look at my friends in the business with serious hand injuries, and months of missed work, I am amazed that this saw is not in nearly universal use.

    The MAJOR reason why SawStop is not more widely used is the cost of the equipment. A SawStop contractor saw costs at LEAST twice as much as higher quality table saw. A trigger of the quick stop is a one time only event without a cartridge replacement which is very expensive just by itself.
    No company wants to license the thing as it has been priced way out of line with what people are willing to pay. Besides, there are plenty of great saw guards and kickback devices available but a are quickly removed by most users. Safety equipment does no good if it is not there!
    If Mr. Gass would let other companies cheaply license then improve and cheapen the technology, I am sure it would be a more widely used.

    This is a powerful example of a pattern in behavior among manufacturers of inherently hazardous products: resist safety technology for a number of dubious reasons while minimizing the horrendous injuries that the products can cause. Blame-the-user is part of that pattern, as are the “safety costs too much” and “regulation is bad” arguments.

    This is historically the case for a range of products that depend on the use of energy, speed and proximity to human users for their performance – motor vehicles, motor boat propellers, table saws, guns, etc. It takes effective legal and/or marketplace compulsion to achieve adoption of safety-technology countermeasures that will reduce injuries caused by such products. The same inventiveness that brought these products into being in the first place can and should be applied to limiting their potential for harm. It’s the behavior of manufacturers and marketers, not users, that requires changing as the first line of product injury prevention.

    W appreciate the honorable mention of Whirlwind here. Your recounting of Steve Gass & SawStop’s long experience with industry reminds me that we at Whirlwind are now experiencing a “deja vu all over again.” Currently I’m considering marketing our “Black Box” device as a build-it-yourself kit for those users wishing to retrofit their current table saw or similar machine. We have product requests pouring in but lack the resources to respond with a finished product. Best of luck to all working this safety problem.
