Ok ladies - go and do a search on the forum for Bottlecap Hole punch tool -- I hav eone - and LOVE it!!!!! It is used for jewelry making and has a beveled edge!!!! I love it! I can whip through hundreds of caps easily!!! My 3 year old is out of patience, http://www.cooltools.us/Hole-Punch-P...-p/plr-100.htm
this is the exact one I have - it comes with a replacement beveled edge - hole is totally fine and fits a split ring beautifully!!!
