It's odd the blade doesn't look rusty at all, just black, though I expect that is rust. I wondered about the handle and blade matching but didnt really know why. There is an etch but it's barely visible, if I clean it up a bit it may become more visible - danger is, I guess, that it may disappear altogether. The teeth arent overly sharp and appear to have mnimal if any set to them. So that needs to be addressed. Alf, 5ppi by my count. Altogether quite a large and heavy thing and the handle while comfortable is a bit bulky but then I have small hands. Chap selling claimed it was quite rare, hopefully not so rare that my attempts to clean and sharpen ruin it. But then if it's not in service it might as well not exist as far as I'm concerned so that doesn't matter too much I spose. Oh, forgot to mention that it appears to have a slight "belly" to the cutting edge. Does that mean its been reshaped / recut at some point or is that a design "feature"?
