Manufacturers of power saws are facing a growing number of lawsuits after deciding not to adopt technology that will stop a saw from slicing off fingers, NPR reports.
Every year, 3,000 Americans lose fingers and thumbs to saws, and another 30,000 make trips to the emergency room for related accidents. But a safety device called the SawStop can prevent the injuries by automatically shutting off the blade of a saw when it gets too close to fingers:
The SawStop saw induces a very slight electrical current on the blade that is monitored by a computer chip inside the saw. Wood does not conduct electricity — but your finger does. The saw can sense the difference between the two and trigger a safety brake.
When the safety brake is triggered, the blade slams down into the table and away from the person’s hand.
Steve Gass, an entrepreneur and patent attorney, invented the device about 10 years ago, but has been unable to convince big power tool manufacturers to use the technology.
“They came back and said, ‘Well, we’ve looked at it, but we’re not interested because safety doesn’t sell,’ ” Gass told NPR. “What a crazy attitude.”
Now, lawyers at a high-powered firm called Boies, Schiller & Flexner LLP are suing manufacturers on behalf of people who have injured themselves on power saws, claiming companies have been negligent because they have not adopted safety products like the SawStop. The firm has already won a $1.5 million case against power tool company Ryobi.
For its part, the industry said it is committed to improving the safety of its products.
“The members of the Power Tool Institute continue to devote substantial time and resources in the research, development, testing and implementation of improved table saw guard designs and other safety measures,” the group’s spokesperson said in a statement.
But this may not be enough for federal regulators. The chairman of the Consumer Product Safety Commission had hoped the safety device would be voluntarily adopted by the industry, and may take action if it is not.
“I believe that if we don’t see a voluntary standard soon, that we should look at making this product a part of our rule making so we can build that in as part of a mandatory standard,” Inez Tenenbaum told NPR. “If we have something that can prevent injury, we need to act upon it now.”


I applaud the invention, but this article seems more than a little one-sided. One unmentioned fact is that Gass, who appears to only be looking out for the poor consumer in this interview, holds the patent on it and stands to gain MILLIONS if it is mandated. The additional cost to manufacturers to implement this technology is estimated to be between $150-$200 per product, an amount that will be passed on to the consumer.
Having failed to charge significant licensing fees to the manufacturers for the technology it now seems the only way to bring it to market is to pursue legislation.
Here’s the problem – SawStop is making a claim that its technology keeps the user safe, even when they come into contact with the blade (ie use the saw INCORRECTLY and in an UNSAFE manner). A regular table saw makes no such claim ad insists you follow good practices.
Now, fast forward to the day the system fails – for whatever reason. The potential for a lawsuit is DRAMATICALLY raised. Basically, no table saw accident should happen for any reason.
But ruling that a product should have a feature for which it was not designed means, presumably, that every car accident victim in America should now be able to retroactively sue for any vehicle not in possession of anti-lock brakes. It’s ludicrous and will eliminate entry level table saws in America as we know them.
Table saws would become a high-end product and the elimination of entry level models (now available as low as $99) would mean greater danger for those who would substitute the wrong tool for jobs that require it.
Also, Why stop at table saws? Every tool manufactured with a blade must now have this new technology or face being labeled in the future as “unsafe” and “defective”.
Where does it end? Where does personal responsibility start?

To avoid the accidents, it is very important to read the instructions given in the chainsaw manual. Also take the necessary precautions when they use.
