From my collection. A relatively rare SG 42 assault knife with multi-functional tools, which was later to replace the classic S 84/98 pattern bayonet used on K 98k rifles. It is the second type that differs in details from the first type. The manufacturer is the Carl Eickhorn company in Solingen, and the internal tools were made by the Robert Klaas company, also from Solingen. According to the traces, the knife was actively used and deployed in combat. After the war, it remained as war booty after the retreat of German troops in Central Europe.
