Not quite sure where to post this. I was browsing Lumberjocks and came across this novel push stick idea:
I think I'd like to make one of these when I've got some time. Hit it with some red stain (so it penetrates) then spray it with peach/white/caucasian colored spray paint. If it ever gets nicked (and I have some nicks on a few push sticks) it will show red, just like a finger. Good reminder.
