I'll be making composite antler/microblade atlatl projectiles for a test coming up soon and figured I should get a little practice in. I also wanted to test the damage created by microblade points against that of a normal old biface so we could see some of the trade offs/benefits/weaknesses attached to each. This gave us a test to see tissue damage and breakage rates between the two very different approaches to finding dinner.

I selected a simple flake that I made while thinning another point a while back. Pueblo type points were made on biface thinning flakes all the time and it's quite common to see a little of the original flake scar on finished points. A quick brushing along the margins with sandstone strengthens the working edge and supplies the first rough outline. Here you're just getting an angle so you can start your first little flake pass. Next I took a few small overpass flakes across the bulb of percussion left from the original flake removal. It wasn't a big task, antler tools typically leave relatively diffuse bulb under the platform. So you don't get a curved point you need to tailor the distal end of the flake back to keep things nice and flat. A curved point will snap in a heartbeat and works about as well as a flying spork.
A few flake passes later and we have our finished preform. Notching on these points wasn't too fancy, just simple shallow notched coming in from the side. Oh! and one last thing, you'll find that a lot of folks oriented the preform so that the base of the point would be along the distal end of the original flake. This means that they used the thinnest part of the original flake for the hafting element, why make a job harder!
The point worked out well and I matched the original illustration in a decent manner. The weapon flew great too...more on that coming soon!
Also, here's a quick look at how the microblade stuff turned out. I did a few things right, a few things wrong and learned a ton. The point in the image has been inset with "microliths", tiny little triangular-shaped blades. The actual microblades are to the side of the point and ended up being absolutely brutal.
COMING UP NEXT ON GETTING TO THE POINT!
