Trench knives of the First World War


In a second-floor apartment, amidst a crowd, a man lay face down in a pool of blood, wearing only a shirt and patent leather boots with accordion-style tops. A knife protruded from his back, beneath his left shoulder blade, buried deep. I'd never seen a knife like that: a large, oddly shaped, shiny copper handle protruded from his body.
Gilyarovsky V.A., Moscow and Muscovites, 1926




History weapons. In the previous material on the topic of combat knives (Combat knives of the Middle Ages) We were just about to enter the First World War. And it was there, adapting on the fly (as they do today, by the way!), that the army had to arm itself with a weapon never seen before – trench knives. They were needed specifically for fighting in the trenches, where long Lebel-type rifles with long rapier bayonets were completely useless. So today we'll be visiting another exhibition, not of paintings, but of knives of a very specific design and purpose. The exhibition will be illustrated with photographs of exhibits from the collection of the Royal Armouries in Leeds, England.


This is a brass knuckle knife, a 1917 trench knife. It was the first brass knuckle knife adopted by the American Army and was inspired by privately owned combination weapons. It features a thrusting blade and a knuckle for both attack and defense. The lack of a cutting edge and its bulk somewhat limited its usefulness, and it was scheduled for replacement in December 1918. The handle is made of a single piece of walnut with three shallow finger grooves.


The scabbard features a round leather body with a steel tip and hanger, secured with blind rivets. A hollow rod is soldered to the top of the hanger, into which a double hanging loop, similar to that used in US military equipment, is inserted. Length: 250,0 mm.


A trench dagger, model 1916, made in France. This is no ordinary weapon, but one with a "subtext." Some of these daggers bear the inscription "Le Vengeur de 1870," a reference to the fall of Paris and France's defeat in the Franco-Prussian War. Although various daggers were issued to French troops during the war, only this one received an official designation. Length: 190 mm. Royal Armouries, Leeds.

Germany was the first country to produce trench daggers of a special design. Although the daggers were produced by different companies, the blade and handle remained the same, while the guard styles varied. Although the scabbard had a belt loop, soldiers often carried these daggers tucked into their boots.


Trench knife — 1900-1930, Germany, Solingen. The blade is steel, double-edged, with a flattened diamond cross-section. The guard and tang are also steel. The guard is short, oval, and protrudes lower than the knife. The handle consists of two varnished wooden scales, each of which has eight ribs in the central part and is fastened with two nails on each side. The scabbard is made of steel and painted black, inside it is a spring lever that holds the blade in place. A leather strap is riveted twice to the back edge of the scabbard, to which another leather strap is riveted, passing around the handle and secured with a rivet. Length - 152,0 mm. Scabbard - length 226,0 mm. Total length - 285,0 mm. Weight - 193,0 g.


Trench knife - 1910-1925, Germany. Overall length: 270,0 mm. Blade: 140,0 mm. Weight: 216,0 g.

The thrifty Germans decided that having a separate knife and bayonet wasn't very cost-effective. Produced between 1914 and 1918, they developed a shortened bayonet-knife for their Gewehr 98 rifle. This all-metal bayonet-knife was called the "Demag."


Here it is, this bayonet-knife with a scabbard. Total length – 261 mm. Blade – 150 mm. Take it off the rifle and... stab the enemies in the trench to your heart's content!

Interestingly, the British had been using the so-called "boarding cleaver" since 1833. It was an interesting weapon that could easily have been used as a trench knife. The guard was made of copper alloy, rectangular, and the blade was triangular in cross-section. The sheath was iron.


"Boarding cleaver." Overall length: 304 mm. Blade length: 171 mm. Weight: 154,6 g (blade), sheath: 60 g.


It's also with a scabbard. Rear view.


A Bowie trench knife, converted from an M10 Ross rifle bayonet. The bayonet's original flat blade was filed down, transforming the weapon into a Bowie-style fighting knife. Such field modifications were popular across the entire bayonet range, as troops on both sides found themselves embroiled in a war that was very different from what they had expected. Made in Canada, circa 1917. Blade length: 258,0 mm.

The French were the lucky ones with the material for trench knives—the steel for them also needed to be found, and their production itself had to be streamlined. The thing is, they had a huge stockpile of rapier bayonets for the Gras Model 1874 rifles in their warehouses.


And the Lebel rifle of 1886 was equipped with practically the same bayonet.

The French began cutting these bayonets into three pieces, welding the tang to the handle. The T-shaped blade proved very convenient. The knife was very durable, although it came in three sizes: thinner, medium, and thickest (near the bayonet handle). Although this feature didn't affect their combat effectiveness! Then their supplies ran out: the "serious war" began, and the French were forced to make trench knives from garden fence rods...


French "nail knife" 1918


Knuckle knife from Sutherland & Rhoden. OK. 1915

The British Empire didn't produce specialized trench daggers, so cutlery manufacturers offered a wide range for private customers. This compact model was one of the most popular. It served as the prototype for the BC 41 knuckle duster used by British commandos during World War II, until it was superseded by the Fairbairn-Sykes fighting knife.


US Army Model 1918 Knuckle Duster Knife. This World War I-era combat knife features a double-edged diamond-shaped blade ending in a point and a cast brass guard that can be used as a knuckle duster. The knife features a pyramid-shaped pommel that can also be used as a weapon or tool. A leather sheath with a belt loop is included. Length: 285 mm. Blade length: 160 mm. Weight: 492,5 g.


A very original knife, the HALADIE KNIFE, circa 1900-1999, features three blades. It consists of two straight, double-edged blades with a flat diamond cross-section, sharing a common tang and facing in opposite directions. The handle consists of two wooden plates, secured on either side of the tang with five rivets. It has a bow sharpened along the outer edge. Its prototype was most likely the Indian kuttar dagger, some examples of which had three blades protruding in different directions. In this case, the middle blade was replaced with a sharpened crescent blade.


British combination knuckle-knife model 1939. Used until 1945.

So, there were a vast number of combat knives that emerged during the First World War. Almost as many as trench batons. However, those fell into oblivion after the war, were never developed, and weren't used during the Second World War. Trench knives, however, survived. And not only survived, but spawned numerous offspring. So today, there are a vast number of them. But that will be the topic of a future article...

    Were our Russian stabbing and cutting weapons used? I've heard of bebut daggers being the standard issue weapon of artillery crews and scouts.
    For example, Siberian rifle units and Cossacks used knives common in their areas of residence in everyday life and in combat...

    In E.M. Remarque's novel "All Quiet on the Western Front," he describes how to use a small infantry shovel in combat.

    I wonder about Arthur's bayonet knife?
    Was the device patented by Lieutenant Pritchard of the 3rd Royal Berkshire Regiment in 1916 for attachment to a Webley-Scott Mark VI revolver actually used in combat? As the saying goes: act decisively, with bayonet and butt!

    "A crude age, crude morals, no romanticism! They don't allow a person to live in peace!"

    greetings to all hi With the development of modern weaponry, hand-to-hand combat is becoming a thing of the past, with rare exceptions. For a modern fighter, a knife is more of a household item than a combat weapon. Nevertheless, history must be known and remembered, and bladed weapons are part of that history! The sheer number of different "picking devices" humans have devised to kill their fellow humans is astounding. fellow Trench knives are part of this history! One can endlessly debate which is better, the American trench knife or the Russian entrenching shovel. Both have taken countless lives. It's clear that trench knives are a dead-end branch of edged weapon development, practically unheard of even by WWII. Modern versions appear periodically, but they aren't particularly popular; in fact, they don't quite fit into the concept of modern knife combat (just as knife combat itself doesn't fit into modern warfare).
    The topic is very broad, thanks to Vyacheslav for the article with excellent illustrations. good

      Yes, the actual goal is to prevent this from happening and to neutralize the enemy earlier and today with increasing success.

        The lines by Yulia Drunina best describe hand-to-hand combat:
        "I've only seen hand-to-hand combat once, once in reality. And a thousand times in my dreams. Whoever says war isn't scary knows nothing about war."

      It is clear that trench knives are a dead-end branch of the development of bladed weapons, which were practically no longer encountered during WWII.

      The widespread introduction of submachine guns into the ranks eliminated them. "Trench broom." A couple of men jumped into a trench, stood back to back, and in three seconds cleared an entire straight section of the trench of the enemy. Knives, forget about them...

    Of the modern knives, I liked the Shokurov Claw, the Silent Soldiers, and the Wagner knife. They shouldn't slip in your hand when someone else's blood is on them, as the first two have rings in the handles, and the last one has rope braiding like Japanese swords.

      This is amazing. My kukri has a proper horn handle, smooth and ringed with just three small hoops. But... even covered in blood, it somehow doesn't slip in my hands. Blood... from butchered meat, by the way...

        I'm simply playing out the scenario of a duel with a Yakut knife, where the blade is intercepted (even though it's double-edged, which doesn't matter if the opponent is wearing a glove) and the knife slips out of the hand due to the smooth handle, likely slippery from blood, ending up in the enemy's hands. The kukri has a widened back like a yataghan, so it won't slip under any circumstances, but traditional knives with simple wooden handles run the risk of losing their grip when intercepted. I just looked at a picture of the new Wagner knife, and it already has a ring near the blade. This is also a controversial design, as it can cut off a finger with a strong blow. A friend of mine lost a finger when he jumped on the side of a truck and his wedding ring cut it off.

            Sorry, I messed up :( I wanted to choose a different word, because the knife is sharp on both sides, i.e. you can cut yourself on the top and bottom if you grab the blade. Maybe it’s double-edged?

          The rings on the handle also have a disadvantage when the blade is intercepted by the enemy.
          My arm is slightly twisted and locked, and the pain is excruciating. Such rings are a controversial decision, and by the way, this was back in WWI.

        The handle could be wrapped with some kind of cord, and the lower part could be bent back, at least for a hand rest—the price would be practically negligible, and the convenience is undeniable. But with such a "weapon," you're more likely to cut your finger tendons than kill an enemy in a greatcoat—your hand would slip on your own blade. Bend your fingers like a prisoner, of course, and it's convenient later, but on the front lines, it seems, the challenges are different.

          Well, they probably did wrap it, they weren't stupid, after all. They did wrap rifle bolts with rags... It's a museum piece, after all. The cords are frayed...

    Hmm, on all the knuckle-duster knives pictured in the photo, the sharpening is directed toward the wrist of the knife-wielder, not the direction of the knuckle-duster's strike. Sideways cutting strikes are impossible, as if the sharpening were directed toward the "leading" edge of the blade. Apparently, the primary focus was on upward strikes at stomach level. I wonder if soldiers were trained in fighting techniques with such knives—if they even had one.

    As a seasoned digger with quite a bit of experience, I can say that trench knives are quite rare to find in positions or anywhere else in combat, unlike bayonets for the K-98 or the Moska. Knuckle-duster knives are a real find. You can buy anything, but again, there's no guarantee you won't be sold a knockoff. Of course, buying one and making one yourself are, as they say in Odessa, "two very different things."
