I am attempting to re-handle a knife for a friend. I glued the handle scales on and was drilling the holes for the pins and on the second hole my drill bit broke. I am sure the reason for this is because the knife is already tempered. Is there a way to dill holes for pins without using up a lot of drill bits or is that just a price you pay for re-handling? I am using 3/32 drill bits and the steel is 1095.
