Hi all... Hope I have the right forum, if not, excuse me... Maybe someone can give me an idea what this is. I ran across this very unusual little folding knife/tool recently. The base of the blade is marked... 'DENVER HARDWARE CO. WARRANTED' The other side is marked... 'GERMANY' Overall length closed is about 2", about 3-1/2" open. Mother of Pearl slabs. The blade locks in place and is released by pushing the rear 'circlip' down. It looks like it is designed to cut a small diameter line or cord(?). What makes this unusual is that the cutting 'blade' is angled into a V shape instead of a straight edge... no idea why. Very interesting!
