Went to work on a piece of obsidian today. About a 4 inch piece, was tired of trying to fix stuff I had already jacked up..
Ended up pretty decent for me. I might work on it some more later because it’s still pretty big.
About 2 1/8 to 2 1/4 long X 2 inches wide at the base. Took my time more today getting it down pretty thin and then worked on it with my ishi stick and pressure flaker.
Notches stalled out on me so I just quit on it before I broke it..
Also picture of my best 8 pieces so far
