Gerber LMF II Infantry Knife 1629
Description
The Gerber LMF II Infantry is an American-made survival knife with a 4.88" black, partially serrated 420HC stainless blade, an insulated nylon handle, and a MOLLE-compatible sheath. It grew out of the U.S. Army's search for an aircrew survival and egress knife. The civilian version has since become a standard in vehicle kits, bug-out bags, and camp gear. This is a new knife from Gerber, not issued surplus.

The LMF II and the Aircrew Survival Egress Knife
Gerber was founded in Portland, Oregon in 1939 and calls itself the largest maker of knives and multi-tools for the U.S. armed forces. The LMF II was engineered under former military man Jeff Freeman to free aircrew from a downed aircraft by cutting through fuselage skin, seat belts, and helicopter Plexiglas. When the Army evaluated knives against its Aircrew Survival Egress Knife (ASEK) standard, Gerber's design met every requirement and outperformed the competing Ontario model on electrical insulation. The ASEK version was approved for military purchase. The LMF II Infantry is its field-tested sibling, built for soldiers and civilians who want the same knife without the aircrew-specific kit.
Blade, Handle, and Sheath Construction
The drop point blade is 420HC stainless steel with a saber grind and a non-reflective black finish. Serrations near the handle saw through webbing and rope, while the plain edge toward the tip handles carving and general cutting. 420HC is not a premium steel, but it resists corrosion and takes an edge quickly in the field. The handle is glass-filled nylon with a high-traction TPV rubber overmold that limits blisters during long work. The tang stops short of the stainless steel butt cap, so the handle insulates against stray live wires and absorbs shock when you use the pommel as a hammer or glass breaker.
Lashing holes in the guard let you bind the knife to a pole as an improvised spear. The ballistic nylon sheath has a fire-retardant coating and a built-in sharpener. It mounts to a belt or MOLLE vest, or straps to your thigh for leg carry.
Truck, Boat, and Campsite
Many owners keep the LMF II in a truck, boat, or 72-hour emergency kit, where the glass-breaking pommel and seat-belt-cutting serrations matter most. Campers use it to split small logs, shave kindling, and build shelters, and owners who carry it around saltwater report very little rust. Two honest notes: the knife weighs about 12 ounces, which is heavy for everyday belt carry, and the sheath grips tightly until it breaks in. Reviewers regularly call it one of the best values among American-made survival knives.

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.
