Hammerstones are made of granite, quartzite or greenstone. The antler billet is used to thin, shape and sharpen the flint tool. The ideal billet is made from the trunk of a moose antler. However, smaller antlers, such as those from the white tailed deer, can also be used. Pressure flakers were made from the upper tine portion of the antler rack.
Many people use copper pointed tools.
Punches used for indirect percussion can be made from antler, or antler tipped with copper. Abraders are made from quartzite or sandstone. An excellent substitute can be a broken carborundum grinding wheel. These are one of the more important tools, necessary for grinding the edge to make striking platforms. Last but not least important are protective gloves, safety goggles, and leather knee pads .
