This weekend I spent several hours flintknapping. I focused on making arrowheads. The weather was sunny and hot, but I took dips in the pool often to cool off. Every time I work on this skill I do my best work so it's pretty fun. I worked with several different materials.

The white piece is made from chert. The rock is very hard and takes a lot more pressure to push a flake off. It's pretty easy to mess up so it was nice to finish an arrowhead. The piece is only about 3/4 of an inch wide so it's not ideal for hunting.

The gray piece is dacite also about 3/4 of an inch wide. The black one is made from obsidian. It's a little over an inch thick so I could hunt with it. The last two are made from glass. I was trying to make the big piece into a spear point until I dropped it. I didn't expect it to break so easily.

Material from left to right (penny for size reference, chert, dacite, obsidian, glass bottle bottom, glass slab)

This obsidian is translucent.

I'm still working on my notches. Ideally the notches near the bottom of this piece would be two or three times deeper in.
