Hi all! I recently acquired a number of items from the estate of a gentleman who served in the US Army during WW11, among the items was a Puma Boot Knife that had several tools in the handle including a corkscrew, awl, can opener and lastly a tool marked Patronenheber MG 34 that apparently is a broken shell extractor. It has wood grips and due to condition appears to never have been used or resharpened. I have found numerous examples on the web of similar puma knives with tools but not finding any examples with the shell extractor. Might keep it for now, just wondering how rare this is and it’s approximate value. Will try to post some pictures of it, once I figure out how to do it. Thanks
