I was thinking this afternoon that Halloween is coming up. In past years my keyhole saw has suffered rust from pumpkin guts, and a couple of years ago one of my kid's friends nicked his hands with it.
I don't happen to have a pumpkin handy for testing, but it seems like this should do the job with less risk to small fingers. It might do curves better if the blade was narrower, but that remains to be seen.
When the time comes, I'll have to print a copy of sliptonic's Jack (0-lantern) knife (http://www.thingiverse.com/thing:4413) for scooping punkin guts too!
