Incredibly cool new safety feature for power tools, it’s a system that can detect when a saw blade is cutting through something that isn’t wood, such as say, the very digits you are using to push the wood through the saw. You get away with a nick instead of a stump. Check out the videos of this thing in action, it’s awesome. They even have slow motion videos. The future products also look as impressive.

It’s proof that we really need more geek woodworkers out there to think of these things, it’s a brilliant use of simple technology to save important fingers (not that there are any unimportant ones).

High School Shop teachers will give this one-and-a-half thumbs up for sure. But really, the big winners here are the hot dogs used to test this thing.
