These Larger 1-1/2 inch copper boppers are a great thing to have if you have to do some mild spalling. They aren’t made for spalling large nodules for hours on end, but they are just right if you have some bigger pieces and your smaller bifacing boppers just aren’t removing large enough flakes. I personally love this size for taking into the field to test some rock before I load it up to bring home to make points. The 1.5 inch heads are loaded with lead for a solid smack, and the handle is solid hardwood. These aren’t necessarily needed for normal arrowhead making, but a great addition to your knapping kit if you plan on growing as a knapper.
