A very useful tool for any flintknapper. This hand-held knapping block helps you hold your point as you pressure flake. Its sanded wood base is perfectly sized to slide into your palm, while the rubber pad on the top holds the flint (or glass) firmly in place. The 3/4" thick rubber pad has a groove running through the middle allowing unobstructed flake travel when pressure flaking. Dimensions 3½" x 2¼".
