FWIW- the unit I have, a Marking Methods 300k (shown in my crappy little video that zaph posted above :foot

is WAY overkill for most knifemakers, myself included.
Back when I got mine, it was pretty much the standard among all the knife makers I could find to ask, and I got a really good deal on it from a knife maker that switched to a stamp.
If you were to buy one now, new, I think they're like $700-800!

It's made for production marking--- like, for instance, marking 1,000 golf clubs a day.

It's certainly worked very well for me, but it is overkill.
Sounds to me like zaph's unit would work great, and the PP seems to get a lot of votes as well. I put my etcher on "#3" (on a #1-5 variable dial) and haven't moved it in about 10 years.
BTW- Adam--- Love your mark, that's very good looking!
