A Bomb Tech's Knife, Born From the M9 Bayonet
The M11 was developed for the US Army's explosive ordnance disposal teams, the soldiers who render safe roadside bombs, mines, and unexploded munitions. It shares its blade with the M9 bayonet but is not a bayonet itself, since it has no rifle mounting catch or muzzle ring. In place of those, it adds a hammer pommel and is built as a working tool for EOD techs, and it is catalogued as part of the military's explosive ordnance disposal tool kit under NSN 1095-01-577-6043. Ontario, founded in 1889 in Franklinville, New York, has been one of the main contractors producing both the M9 and the M11 for the US military.
Blade, Handle & Construction
The blade is roughly 0.28" thick, far heavier than a typical field knife, giving it the strength to pry, scrape, and dig without snapping. It is 420 modified stainless hardened to 53 to 57 HRC, a softer steel than premium knife alloys, chosen because it resists rust and corrosion, flexes rather than chips under abuse, and is quick to resharpen in the field. The black powder coat cuts glare, and the milled sawteeth along the spine handle notching wood, scoring material, and cutting through rope or cordage the edge struggles with. The tan Kraton handle is grooved and textured for a secure grip with wet or gloved hands, the steel guard protects the hand, and the steel pommel works as a hammer.
Beyond the EOD Kit
Off the base, the M11 makes sense for anyone who wants a heavy, nearly indestructible utility knife that can also pound and saw. Overlanders and off-roaders keep knives like this in the vehicle for cutting straps, clearing brush, and breaking through materials in a pinch. Its thick spine and hammer pommel suit campsite jobs like driving tent stakes, splitting kindling, and notching poles. For collectors of modern US military gear, it rounds out an M9 collection with its more specialized EOD sibling.

Curious About Sizing?
Given the massive variety of clothing we carry, a standard sizing guide is incredibly helpful for customers seeking the best fit.
Please understand that surplus varies widely in fit and cut and this sizing chart is general advice rather than tailor-level fitting.
Nearly every military has different sizing charts and schemes, which is why we've taken the time to put together this brief tutorial.
Jacket & Shirt Sizing
In absence of an established military size chart, we measure each jacket or shirt from armpit to armpit to get a rough idea of how it fits. If a garment is between sizes, we mark it one size down. For example, if a shirt measures 19.75" from pit to pit, it is marked as a small rather than medium.
To measure pit to pit, close up your shirt or jacket and measure from armpit to armpit.
This is our measurement guide that we use to measure garments without an existing military size chart:
14"-15" PtP = XXS
16-17" PtP = Extra Small
18"-19" PtP = Small
20-21" PtP = Medium
22-23" PtP = Large
24-25" PtP = Extra Large
26-27" PtP = XXL
28-29" PtP = 3XL
Pant Sizing
We typically convert pants to US waist and inseam sizes. If a pair of pants is between sizes, we mark it one size down. For example, if a pair of pants measures as a 33 waist, it is marked as a 32 waist.
To take these measurements we lay a pair of pants flat on the ground. We then measure across the waist and double the measurement. For example, if a pair of pants measures 16" across the waist it will fit a US 32 waist.
To determine inseam we measure from the crotch seam to the bottom of the cuff. For example, it a pair of pants measures 30" from the crotch seam to the bottom of the cuff we will list it as a 30 inseam or 30L.
