How you name your knives. I'm not sure about the rest of the line, but EB must stand for Extra Bada$$. I can't wait for the folder. (what could GB mean?)

All the names are a supposed secret of theirs.
I pretty sure the DB is initialed after a certain someone and respected forumite who helped design it and maybe the EB is a step up from the DB (abcdE), because I remember a post where mick was calling it the 'db squared' or something like that.
From my impression of them (though not a bad one), the names can probably get pretty damn twisted.
