I picked this one up on a chat forum, and I love it. Take a broken flex-head torch, cut the barrel and neck off, leaving the head (no cup). Use a rooster-tail, and the collet and body appropriate for the tungsten you're sharpening, and you have a long-handled "pin vise" with a large, easy to control grip. This beats every other manual sharpening method I've ever used.
I prefer simply clamping a 4 1/2" grinder with a 120 grit flap-disc to a pipe stand, locking it "on", and sharpening several at a time.
