A rare and genuine early example of the famous ersatz (EB1) Crank Handle bayonet made by Deutsch Maschienenfabrik AG (DEMAG), Duisburg. DEMAG produced these bayonets between 1915 and 1918. The makers mark is stamped on every blade. There are four variations of the markings dependent on the period of production. The “DRGM” stamp on the ricasso of this example, and the “DEMAG. Duisburg” circle on the obverse indicate that it is one of the 1915-1916 production knives. Designed to fit the G98 rifle the bayonet has a very distinctive handle shape, earning it its “Crank Handle” nickname. The 148mm double-edged blade is in great condition, free of rust or pitting and still sharp. The blade is stamped on both sides of the ricasso with the maker’s logo and the spine bears an inspection mark or waffenampt. The blade retains its original leather washer. This is one of the best condition blades that I have come across. The riveted grip retains patches of its original feld grau paint; testament to the trench knife’s working life. The sprung bayonet attachment mechanism works perfectly. The original steel scabbard retains much of its black paint but the leather belt loop is missing. This is a rare and sought after early production model of the iconic German World War One trench knife bayonet. There are many fakes of this sought after knife but only the originals have peened rivets in the grip and are marked on the spine with an inspection stamp. The leather-retaining strap – when present has a “snowflake” style pattern on the press-stud. The snowflake is missing from the press-stud on the fakes. There are other differences between the real and fake models, such as blade and crosspiece thickness but the above pointers are easily spotted without the need for callipers or in-depth knowledge.
