Making Tools II – Bone

Bone is surprisingly resilient. Once dried and hardened, it is comparable to some types of stone. In order to create stone tools we used a method called abrasion. Once a suitable piece of bone has been selected, a rock with sufficient grain size is selected. Sedimentary rocks from the silica family, like sandstones, work amazingly well for this–think sandpaper.

I created a bone hook and a bone projectile point by abrasion. The point was 7 cm in length and .5cm wide. It took more than 3 hours to abrade it to the designed thickness and to hone an edge.
