Stopping a Saw Blade with Electrical Capacitance [video]

These look soo good - I'm really surprised they haven't been licensed out to other saw manufacturers. I saw a demo of the inventor actually sticking his finger into a running saw. I know they're expensive to replace when they trigger - but a lot cheaper then replacing fingers..

I really want one for my home shop when the prices get a bit lower (last I checked, they were a couple of thousand...)

Laser cut edges are conductive, and will trigger a saw-stop.

Do NOT use on material after it has been laser cut. The charred edge will trigger it. (There is a way to turn off the feature, somewhere in your owners manual)
