423. Bright Idea: the SawStop August 5, 2007

How about this for a Bright Idea: keeping your fingers from getting chopped off. Watch this amazing 1- minute video of a circular saw blade instantly retracting when in contact with flesh (this demo uses a hot dog). The inventor was a woodworking physicist who developed and sold the product himself after a hardware company turned him down. Check out his website HERE; via The Big Idea.

Can you guess how the blade distinguishes wood from flesh? Click on for the answer…

The inventor made his prototype in one day by utilizing the same device used on touch lamps. The metal of the blade detects the slight electrical charge of the finger. Brilliant.

I saw this on the Big Idea as well. It’s a genius concept. It’s crazy that this guy got turned down by a hardware company–guess he’s laughing all the way to the bank not to mention saving countless people’s hands.
