I started by playing with some clear glass. I made a biface, and took a few flakes off. Once I was convinced I was somewhat competent again I got to work on a beer bottle bottom. I was almost done a small "bird point" when I got greedy while thinning it and snapped it in half.
The next bottle bottom was less concave, and turned out nicely. I didn't thin it as much as I could have, as I was worried about breaking it again. I tried a new style of notching, and I am pretty happy with it. It eliminates the grooves cut into the cutting edges of the head. I always felt that those must impede penetration.
The head is only slightly longer than it is wide, so it has a lower mechanical advantage than a longer head. I am confident that it would bring down a deer, but I would prefer a longer head for that. I think this head would excel on raccoon sized animals. If anyone's curious the head weighs 70 grains. Glue and hafting material would add to the overall weight at the business end of the arrow. Anyway, here are some pictures of the finished product.

Very cool! Any plans to see what variations you can successfully produce?
ReplyDeleteI have already done a few variations. I started with a triangle that just had two little notches along the sides. Then I tried corner notching, but I had trouble attaching those to arrow shafts. This was the third variation.
DeleteThe next variation will likely be this but with notches along the sides as well as the concave bottom.
