(July 3, 2020)—This project involved flintknapping, whittling, and drilling.

I started with a roughly circular piece of rhyolite I’d gathered in Mule Creek, New Mexico. I flaked it into a biface, then thinned it so that it would be easier to drill (here’s a video showing how to flake and thin bifaces).

After about 30 minutes, I had thinned the biface from 18 mm thick to 7 mm.

Drilling was the most difficult part of the project. I used stone drills hafted with pitch. I wore out 30 drill bits! And it took 6 hours to complete the perforation. I had to don gloves after about an hour—my poor hands! I did spread the process out over three days, though.

Next, I cut out the forked handle.

Next, I carved a small stick to fit through the hole I’d drilled. I made sure the stick was long enough to go through the forked part of the handle. I drilled holes through the forked tines to run the dowel through. Getting it all to fit properly was a little tricky. This part of the project took about 45 minutes.

I pushed the dowel through the disc and into the other side of the forked handle. I cut two thin leather strips and ran a bead of adhesive down one side. I wrapped these on either side of the disc to serve as washers.

I used a bit of adhesive to hold the dowel into the handle, as well. Now the cutter was ready to go!
