belt hole puncher. It's a super-simple to use tool that comes with a variety of prong sizes for punching holes. With it, you can add new holes to your belts in a snap and end up with a great fit. Definitely worth every penny! I wouldn’t recommend this for belts that are several sizes too big, because there will be too much length left over.
Here are some tips for using the belt puncher so punching those extra belt holes can be a breeze. Know that the hole puncher does not make clean holes as it doesn’t quite cut through. To solve that use it by holding the lower handle (the one with the striker plate) firmly on a flat surface. With the lower punch handle anchored on the table top, simply press only the upper handle to bring down the revolving punch head. This technique will help you punch holes with less effort! To prolong the sharpness of the punch edges, put a small piece of strong cloth (like denim) under the belt to be punched. This way you aren’t hitting the end of the punch on the back metal plate.
