This knife falls into a whole different category. It is personlized with all the owners battles and engagements. Some engravings are war time done and some were post war done. The knife names his paratrooper unit of the first dvision A.R.1. Every square inch has been engraved and he engravings from Russia to Italy to Poland and to Normandy. He was named Erwin Forkel. The grip has slashes on the wood but I am not sure if they are for kills or jumps, five notches in total. The marlin spike is waffen proofed the spring is tight. This is a truely rare piece for the para collector or the edged weapons collector. This is truly a work of art and unique piece.
