Inventor Demonstrates Safety Saw With His Finger

How strongly do you believe in what you make?

Every inventor offers promises and guarantees to convince people to buy their products, but how many would stick their finger in a table saw? That’s exactly what the inventor of the SawStop did.

This incredible device uses a capacitance sensor to distinguish wood from your finger. Then, a metal brake stops the blade so fast you only get a scratch. Watch the video to see how it works. If you just want to see him put his finger into the table saw, fast forward to around 4:00.
