What Jig, if any, do I need to sharpen a pocket knife or one of those Leetherman multi knife ?
There is no specific Tormek jig for very small jigs. However, Ionut and I have both made suggestions for modified jigs on this forum. Ionut actually made a unit and posted photographs. Another option would be carefully hand holding the tool resting on the universal support bar. Have your grindstone graded fine and use a light and patient touch or you will end up with a microknife.
Search the member list for us and bring up the older postings. There were several. I don't remember the exact time frame, but it was most of a year ago.
