Caveman, my friend Barry did most of the work on that bow, I worked on it a good bit and Pat B carved on it some also. We did it partly as an experiment to try different replica tools made from local rock, but you could make do with simple spalls and flakes. We cut the hickory sapling down with a rhyolite hand axe, cut it to length with a hafted stone celt and hafted quartzite Guilford flaked axe. We split it with an antler wedge, a rhyolite spall, and our hands. A lot of the reduction was done with a rhyolite adze and a big sharp-edged spall of rhyolite. We used a piece of rough sandstone to do some sanding and rasping on it. The nocks were cut in with a sharp flake with serrations pressure-flaked to make it into a mini-saw. We used snapped flakes for scrapers. All in all, it wasn't that much harder than using metal tools. Most of the reduction work was done while it was wet and green.
