Went to local Ace hardware store to get some brass rivets for a sheath I made(like the looks), anyway bought a bunch of them thinking that all you did was put them on a hard surface and peen the bottom to flatten out, well that didnt work so can anyone tell me if there is a special tool or a different way to do it. They had some split rivets but the heads on them were too big to look good on my small sheath....Thanks, Dean-- If you have a pic of the tool if there is one could you post a pic of it..??
