German WWI Trench Knife

German First World War trench knife, commonly known as a Nahkampfmesser, meaning close-combat knife. This type of weapon emerged from the practical realities of trench warfare, where long bayonets and rifles could be awkward in narrow trenches, dugouts, communication lines and night raids. A compact knife could be drawn quickly, carried easily and used in confined spaces. Sources identify the German Nahkampfmesser as one of the typical trench knives of the First World War. 

Its design was generally plain and functional. Typical German WWI trench knives had a steel blade around 5 to 6 inches long, either single-edged or double-edged, with wooden or sometimes synthetic grip scales secured by rivets or screws. They were usually carried in metal scabbards, often fitted with a leather retaining strap or belt loop. This construction reflects their purpose: not ceremonial display, but close-combat and field use.  

Historically, these knives were produced in several similar patterns by different German makers. The Imperial War Museums holds an official German army issue trench knife from the First World War manufactured by Clemen & Jung of Solingen, described as one of a number of dagger-like knife patterns produced by German cutlers for military contracts. Solingen’s long-standing reputation as a centre of blade production made it especially significant in this field.  

The German trench knife reflects the brutal practicality of modern war. The First World War was dominated by artillery, machine guns, barbed wire and fortified trench systems, yet much fighting still occurred at very close range. In this environment, short knives, clubs, sharpened tools and improvised weapons became part of the soldier’s equipment. Sources note that early in the war many German and Austrian soldiers carried privately purchased hunting knives, while the German army later issued Nahkampfmesser as standard equipment for both combat and more utilitarian field purposes.  

Collector’s note: German WWI trench knives were not a single rigidly standardised model. Many variations exist, differing in blade profile, grip material, scabbard construction and maker. This variety reflects wartime production needs and the demand for compact weapons suited to close-quarter trench fighting.
