I wanted something primitive looking and couldnt find any knapped flint blades,had to get obsidian..Broke one blade before I even got started and found out fast how fragile obsidian is..Heres what can be done with a 1/4" piece of 1095 steel and a small air grinder with a carbide tip..Top knife is made from 1095 steel,bottom knife is obsidian..Top knifes blade was blued,buffed and acid etched and buffed again to give it a obsidian shine..Added a deer antler handle and beat up brass guard
