. . . . NEVER set you knife down where it cannot be seen from ten feet away.
I'll add unless you are working at a table or bench
and set it directly in front of you for the briefest
of moments.
I've known several who set a knife down, and
when they realized it was gone, they didn't have
the first clue of where they left it at.
Any folder I'm using gets pocketed immediately
or wiped off before returning to the pocket if
needed.
