I use this to punch a hole in the center of metal bottle caps. The hats fit well. It's taking me longer than I thought to deal with more caps at once. I could use a more expensive tool that doesn't require me to hold a punch, but for crafting it's out of my budget! (I need about 150 bottle caps for the snakes I make.) It's easier on my shoulder than punching a hole with a nail. that works pretty well. I've found that I often have to adjust the bottom or the stamp isn't clean. I love that the cut piece doesn't fly out so I can do it in the living room while watching TV. One thing that drives me nuts is that the tie adjustment tool is not in its allotted place and not secured in the case. It just doesn't fit properly in the recess.
