I view tapping or using the heel of the frizzen as a field expedient. It works for a few shots but it is more chipping than flaking. Sharpening this way results in blunt edge profile that doesn't last very long. If repeated often enough the striking edge can become nearly round. On the other hand, pressure flaking done correctly removes tiny thin flakes precisely where they are needed and can maintain the original > striking edge and prolong the flints usable life. This is because the applied pressure is directed more inward than downward. Pressure flaking tools can be made from either antler or copper. Steel doesn't get a grip or bite on the flint and doesn't work as well
thank you so much for the video you provided. will a ground deer antler also work as well? it is indeed so simple. I have deer antlers no elk , or moose?
