Well the obsidian is easy, couple rainbow and midnight lace. The chalky, gritty stuff is my creek burlington. There are 2 made from Kentucky black and the big blade out of Tx perds. The 2 tone laying on the rock is high ridge burlington. That stuff is just amazing to work! The middle knife with the red paduak cap has an Agate blade (maybe Paiute agate) that came from Joe.
Thanks for looking!
