Looks like a Puma, not marked, though. Wet sanded on it, used some rust removing gel, took all the way to 2000 grit. Got somewhat of a mirror finish, on the flats. Should have took a “before” pic, didn’t think about it. Would like to get a sheath for it. My leather crafting only extends to riveted axe masks and machete sheaths. Not willing to dive deep enough to learn stitching. My first choice would be a horizontal carry (scout) kydex scabbard.
