So why are the big power tool companies refusing to use it?
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.
