If any of you punch a bunch, like me...then I'm sure you have a few punches that are dull and won't punch as cleanly as they did when you first purchased them. To resharpen your punches, all you need to do is grab a few pieces of tin foil and punch punch punch till you feel like your punches are clean. In the photo above, I've used waxed paper and punched until I felt like my circle punch would punch out a clean circle. Voila, it did!
Now go grab your inexpensive tools from your kitchen and clean your punches!
