PANOVOS 2Pcs Precision Pin Vise Model Hand Drill Tools Set

I bought this to hold and sharpen tungsten electrodes. Smaller then I thought, and does loosen up so when I try to sharpen shorter tungsten electrodes it loses its grip and do to it not being thick enough its cramps up my hand a bit after a short while.

I use these almost everyday, i will be buying more soon. it would be nice to take the top knobby-thing off so it fits in the drill press though...

I bought a couple of pin vibe from here and these are awesome very easy to use very comfortable in your hand in the future I will buy some more
