Hi Everybody. I am a little new to this. So I bought the Tandy Mini and Maxi Punch Set for setting holes. But when I got them out and tried them, they were all unsharp and dull and didn't punch through anything. And I don't like the rotary kinds either. So I've decided that getting individual hole punches would be better. I want to use the hole punches for standard holes like i.e. belts, holes for putting in snaps, rivets, etc. There are so many hole sizes, so I was wondering what are the standard hole sizes for those things? Thanks!
