I've got one of those Voos jacks, with quite a bit more life on it. Had a pin missing, Bob Picklesimer took care of that and cleaned it up (don't scowl, I bought it for dirt cheap and already have put my own patina on it
).
He also took my old Remington barlow down from a one and a 1/8 blade (just a nubbin on the pen blade). I've been carrying the Tom Sawyer two blade barlow with the 2012 forum knife. Redundant, yeah, but I think I might leave the forum knife at home in favor of trying the Voos jack with the barlow.
