Yeah,the Native Americans made them out of flint with bone handles,antler, etc. The closest thing to one I ever found was a stone-age multi-purpose tool. It could true arrow shafts,cut sinue,skin small animals & the like. Fire stones,arrowheads,etc. The fire stones are well used too. But a flint knife would be cool. I've seen pics of flint swords,but only ever found the chips from them. I remember a story once where the natives called them buffalo knives. Musta took guts to sneak up & pig-stick a grown bull. I saw a mounted head from one once that was as big as me!
