Hi James

I've got something similar at around the same size as well, no maker mark on mine but it is double etched. Don't know what mine is for either.

It seems a little cumbersome for carving, mine shows no sharpening and is a plated blade, with the two blood grooves to the bottom edge I had supposed it was some kind of hunting knife, this thing could stick a boar easily, the weight is substantial.

Nice to see another

Cheers

Gary
