Keith, the medals that they send out for the New England Homebrew Competition are engraved wood. Pretty sure one of the guys in Brew Free or Die (the ORIGINAL CLUB not the micro-brewery founded years later) have a machine that does it.
I'll get a pic posted in the next few days to show you.
They are really nice work and you might want to use something like this for your tap handles, if I talk to the right guy it might come pretty cheap too.
Love that label, not as hard on the eyes as some of the other ones yet its still an attention gettah
