I recently came across a post in another section where someone mentioned drilling out the handle of his Leatherman Supertool and grinding down a couple of the blades to lighten the weight. Sounds like this should work, but before I end up with a pocket full of scrap metal -given my machine shop skills! - I would like to hear from anyone else who has tried this. Any particular recomendations? How much can you take off before seriously weakening the handle? What size holes have you drilled? Any help most appreciated!
