Why buy an M3 Trench Knife?

The M3 Trench knife was developed during the opening stages of WWII with the design being accepted and put into production in 1943. The knife was a replacement for the woefully inadequate 1918 Mk 1 trench knife which was developed in the closing stages of WWI (the old brass knuckled trench knife) Soldiers who had carried the Mk I found it difficult to use due to the brass knuckle grip which was slippery when wet, cold in the winter and prone to freezing to the scabbard. It also sucked for any other use than punching and short thrusts. It was very difficult to fight with and could be used for little if anything else. Thus, a simplified less slippery grip was developed and a more utilitarian blade design was developed.

The new knife, however, was to remain a chiefly a fighting/thrusting knife, with its chief purpose to be a bayonet substitute for soldiers who did not get issued a bayonet. Thus it was issued to BAR gunners, Tommy gunners, and soldiers manning crew served weapons for hand to hand fighting, not for cutting down brush or opening K-Ration boxes. The M3 was later modified and became the M4 bayonet and issued alongside the M1 Carbine. The basic blade design of the M3 knife was used on subsequent bayonets used for the M14 and M16 Rifle.

While not a revolutionary design, the knife was functional and got the job done. The fact that its basic design was carried on in subsequent military issued bayonets says something about the knife (or the military’s love affair with the M8 scabbard!)

The M3 was initially issued with the M6 leather sheath which was not well received by the soldiers. It’s simple riveted design and poor water proofing left it prone to rotting and falling apart. The solution was the adoption of the M8 and later M8A1 scabbard designed with a fiberglass body and steel throat. The scabbard was also used with the M4 Bayonet and several subsequent bayonets.

A small snippet of information: While the Fairbairn-Sykes Fighting Knife (Commando Dagger) may have been the most famous fighting knife produced by the British during WWII, the British SAS quickly adopted the American made M3 trench knife as their EDC fighter because it was a much better quality and more robust fighting knife. (They used the M3 Trench Knife in Italy and later in North West Europe, not during the desert campaign. They also adopted the M1 Carbine at this time. The knife also saw use in the Malayan Uprising)

As for purchasing the Ontario or Boker version, I’d lean toward the Ontario but would pick up a US issued M8 scabbard. Another option is to pick up an original issue on eBay that was manufactured by any of these companies: Aerial (Aerial Cutlery Mfg. Co.), Boker (H. Boker & Co.), (Camillus Cutlery Co.), Case (W.R. Case & Sons), Imperial (Imperial Knife Co.), Kinfolks (Kinfolks Inc.), Pal (Pal Blade & Tool Co.), Robeson (Robeson Cutlery Co.), Utica (Utica Cutlery Co.)

Is there a better fighting knife out there? I’d say there is always a better fighting knife. But were these other fighting knives issued to the U.S military and our allies during World War II? With the exception of the M2 Fighting Knife (Marine Corp Ka-Bar), I can’t think of better Government issued fighter from WWII.

That's my two cents.
 
The M3 is an attractive knife and I admire it greatly for its looks. Makes a pretty decent 'stabber' but it will not take and/ or keep an edge. It simply cannot, based on the design. So not much of a slasher knife, not much for digging a foxhole. The first ones with the stamped Model, date, maker's name stamped onto the blade, tended to break there. Will todays Ontario and Boker do the same?

The US military did use the blade design for a long, long time, all the way up to M7 bayonets; was that because of decisions made by economics? I dunno. But honestly, as I pointed out in another recent thread about this knife, the technology is 60 freaking years old. There are so many better designs out there today.

On a good, nice looking reproduction: Find one of the Camillus repros. Unlike Ontario, Camillus actually made one during the war. Their repro was so good they added a little detail so collectors can tell the originals from the repros.

Here is an example of what a person can do to put together their own M3, starting out with an M5/M6/M7 blade, some leather washers and scrap metal for the guard and a brass fitting shaped into a pommel.

Yes, there are definitely better blades on the market but if an M3 or similar style bayonet (M7) is all you have you can certainly make do. They don't come with much of an edge but with a little elbow grease you can get those things hair poppin.

I have an old M6 bayonet that shaves hair off my arm and is very solid. I have split wood, carved and just generally used for mundane things. Holds its edge reasonably well for 1095 and takes alot of stress. Its more about the person using it than anything else.
 
Looks like a competent combat knife. I want a fighter with a knuckleduster grip. Never know when you gotta regulate on a #ucka.
 
Toby G and OldKnife, thank you for the fascinating details.

Out of curiosity, could you recommend some sources that descibe soldier's reactions to the utility of WW II knives? The stuff I read generally describes how knives were made, by whom, and how and when they were issued. There is little on how they actually fared in te field or what the infantry thought of them. Any volumes I should look at.? My thanks in advance.

By the way, I found this to be true for firearms as well, all the way up to tanks and artillery.
 
Charlie Mike,

I got yer Knuck knife right here. A Swiss type 57 stainless steel blade of 9 1/2", just under 1/4" thick, mated to a repro US 1917 trench knife guard, making the weapon 14 3/4" long overall. Heavy brass pommel, blued, primed, painted like the guard. Weight is 15.8 oz, the balance point is right on the index finger when held in a fencing grip.

Practical in combat? Depends. What trooper wants to carry an extra pound of steel (one in a thouand chance he will use it in combat) when he could tote long distance fighting ammo or addtional food / water instead? But in the hands of a berserker engaging in a WW1 trench raid?

Any thoughts on the Boker M3? I'm considering getting one.

I have had the Boker M3 for awhile now.I have stabbed it into the bottom of aluminium beverage cans,and into coffee tins without any damage. Many have said before that it's a great buy for the money.The blade is made of Chinese SK-5 which is a tough steel which takes and holds a razor sharp edge.The sheath is made in Germany,looks good but authentic ??? While,I don't have the Ontario M3,I do know it made of 1095 steel.
 
If you want one get a camillus. They make reproductions of the original out of carbon steel. I like mine.
