Many of you have likely seen this. I saw it for the first time today. If anyone has done this or has such a razor, let me know.
I have. It'll shave if you knap the obsidian carefully. In all honesty, the time and effort used to make it aren't worth the end result, unless you're making them to sell.I remember seeing that a few years back. I always thought it was pretty neat. Would anyone here try it?
I still have a faint scar from my early attempts at knapping obsidian. Those flakes can be so sharp you'll notice the blood well before you relizing you've cut yourself.I've knapped a few knives and razors from obsidian. The edge will not be straight. Will it shave? Yes.
But technology has given us much better.
