What bone head gave you that advice?

In rea life, if you show up to look at a boat for sale, and want to use

a hammer to "sound" the decks, the owner (or his rep) would yank it
away
from you and smack you with it.

Doug...do you EVER work with a surveyor? Do you have a clue as to what
KIND of hammer is used? Here's a hint...it's small and not heavy! Ever
hear of a phenolic hammer?
Doug, I used to think you knew something and now it looks like you're
full of crap like Loco.
