I have to ask.... was it FOG? If not, that thing should go into the "Hall of Blades". If it is fog, it is still one of the finest flint blades I have seen. It would definitly compete with any of the Obsidian fog blades being made. Simply AWESOME any way you go about it.
Another question.... I have been seeing a lot of posting with this "River Flint". I would love to get my hands on some. Are you purchasing it, finding it, trading for it?
That thing deserves some kind of special handle. That is one hell of a blade!
