This is a hard question. But on saturday I was thinking about it in the basement. And I saw my dads table saw and I thought “hmmm wouldn’t be nice if I could use that safely?” Yes it would.
So I thought about it a little bit and I think it would be a cool invention if someone makes a table saw and when it is close to your finger it stops and won’t go until you move your finger.
