Hang in there on the riviting tool. I bought one from Historic Enterprises for dome-head rivited mail, and it just doesn't work with the IceFalcon mail - different size dome, or something. I bought the IceFalcon pliers, and they work fantastic. I suspect the HE dome heads are slightly larger than the IceFalcon ones, which I would have never guessed is the case before. If you have GDFB rings, get the GDFB pliers; if you have IceFalcon rings, get the IceFalcon pliers; etc.
