The triangle point on the left is a form of obsidian that I`ve never seen before, don`t know for sure who sent it to me in a package of rock to try out but it shows a kinda purple when backlit... Middle preform/blade is keokuck , & the glass is from a broken display case, gotta save the "brokes" if possible... repointing , rebasing, or repurposing all work in their own ways... Hope you like `em.
