It's rare. It's very traditional and easy to forge. It has a grain much like Damascus and if ground correctly, the grain shows through very nicely.
On this, I wanted it because this was old and I wanted the thing to look like it's been buried for a hundred years. I even went back beyond the weld and forged in some cold shuts to etch into grooves.
I will age the handle and furniture also.
Who knows, maybe Wallace Gussler will see it, think it was made in Colonial Va, and put me in his next book (private joke)
