Ever been intimidated, even just a little, when having to use a table saw or chop saw or other high speed dangerous device in the shop? This new technology should help rid any fears you might have of not being able to find 2 or 3 fingers before you have to rush off to the hospital due to blood loss. You couldn't cut your fingers off with one of these saws even if you tried!
SawStop <--- go and watch those videos. Impressive.
I still have all my digits, but here 'n there over the years I've had a few blades kick, snag or bind up on me with my hand way too close for comfort. Had it been installed, this technology wouldn't have changed any those incidents, but just knowing it was there may have put me a little more at ease.
