I have a large quantity (~ 120 lbs) of nice obsidian, both black and mahogany . Looking to trade for a knife or two. The obsidian comes in a couple of sizes, (3 lb -5 lb ) and (1 lb - 2 lb ) .There are no small pieces in the lots. If you knap points or knives, this material is for you. I'm interested in getting a couple of knives.
Willing to hear other propositions.
