I have a speical tool that I believe is for straightening wire wrap pins - it's a Xcelite X100 screwdriver that has been provessionally modified - the phillips end is cut off and there is a hole drilled in the center of the shaft - it is stamped MT2824-gm
It would also be useful for making bends in spring wire, etc Hole diameter is 40 or 50 thousandths (I'll trade this for some gauge wires so I can measure things like this accurately)
If you want it, $3.50 will cover shipping and buy my wife half a cup of coffee as a reward for walking it to the post office.
