Hope this is not terribly off topic, but I just saw a story on MSNBC about a 3 year old boy who may have saved his dad's life by making a 911 call. His dad had accidentally (no suicide attempt) severed an artery with a wood chisel and apparently was in a lot of trouble.
I think one big advantage hand tools have over power tools is safety. I can stop when I see blood before much damage (maybe a few stitches but not much more). I guess we'd better watch out for where the business end of our chisels might go.
