16 obsidian Preforms, bifaces for flint knapping.
16 mixed type Obsidian Bifaces for flint knapping arrowheads, knives or spears. Types of obsidian include mohagany, triflow, snowflake, silver, banded, rainbow, lizard skin and more.
These would be great for anyone wanting to work with obsidian. They are left a little thick so percussion knapping will be needed.
