The TOPS Mountain Lion (MTLN-01) is a full-tang, American-made fixed blade knife with a 5.5-inch 1095 carbon steel blade and layered green and black G-10 handles. TOPS designed it with active and retired soldiers of the US Army's 10th Mountain Division.

A Knife for Mountain Soldiers
The 10th Mountain Division was formed during World War II to fight in terrain most armies avoided. Its soldiers trained on skis and climbing ropes at Camp Hale, Colorado, then broke through German defenses in Italy's northern Apennines in 1945. Today the division is headquartered at Fort Drum, New York, and it remains the Army's light infantry specialist for cold weather and rough country. TOPS worked through several rounds of design ideas with 10th Mountain members to build the Mountain Lion, and the result is a blade meant for both hard tactical use and the ordinary chores of life in the field.
TOPS Knives has made its knives in Idaho since 1998, with a design team drawn from the military, law enforcement, and the survival world.
Steel, Grind, and Grip
The blade is quarter-inch 1095 high-carbon steel, hardened to 56-58 HRC and shaped into a recurve drop point with a mid-height saber grind. That grind leaves plenty of steel behind the edge for chopping and prying while still slicing well, and the recurve belly pulls material into the cut. TOPS applies its black traction coating for rust and glare resistance, with a satin swedge on the spine to slim down the tip. A notched thumb ramp and a deep choil give you a forward grip for close, careful cuts.
The exposed full tang is capped by contoured scales of layered green and black G-10, a fiberglass laminate that stays grippy in rain, snow, and sweat. The knife ships in a black ballistic nylon belt sheath with a front accessory pocket, a leg tie, and MOLLE backing.
What It's Good For
The Mountain Lion is built for people who want one serious belt knife on a backcountry trip or at deer camp. The thick spine handles batoning firewood, splitting kindling, and cutting shelter poles, jobs that would snap a thin hunting blade. The recurve edge also makes quick work of rope, tarp cord, and food prep around the fire. One buyer told TOPS he gave his to his daughter as she headed into the Army, and it is a common gift for soldiers, hunters, and anyone assembling a serious survival kit. Keep a light coat of oil on the edge and swedge, since uncoated 1095 will spot with rust if it is put away wet.

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.
