During the Second World War, the production of copies of the M-1937 / II slings was organized in England to arm the personnel of reconnaissance and sabotage units. The training program for hand-to-hand combat of the special forces of England during the war included training in the conduct of combat with the English analogue of a knife, including the use of a pile-awl for silently removing sentries. English sling cutters differed from the German version only in nickel-plated metal parts and black plastic linings made of bexoid. The first batch of these knives in the amount of 500 pieces. was manufactured at the enterprises of the company "George Ibberson & Co", Sheffield (in total, over 3 thousand of these knives were made during the war). Almost the entire batch of these knives was subsequently drowned in the North Sea and a few items have survived to this day.  * [Additional screenshots](http://www.artstation.com/artwork/q9gwVP) Source: Objaverse 1.0 / Sketchfab
