This week for my Cool Tools review I’m going to show you a fancy automatic center hole punch, great for marking and starting drill holes in metal and wood. I’ve got an Amazon link for this in the show notes, and if you pick one up you help to support my videos and the Cool Tools blog.

These are Knipex High Leverage Cutters (Amazon link). They cost around $35-40 on Amazon, which isn’t cheap for a pair of clippers, but they seem indestructible. They’re drop forged, so they’re extremely tough. They’re rated for cutting through Piano Wire, which is essentially tempered spring steel and easily damages most cutters.
