FirstEdge model 5150. Plain edge elite field knife. Includes knife & sheath. New & authentic. Info & specs from FirstEdge:

The FirstEdge 5150 Elite Field Knife was designed in partnership with U.S. Elite Forces and is currently used in training and deployment. This is a very rugged and versatile knife that can be used for multiple applications, from Survival to Everyday Carry. The knives are made with ELMAX Steel, a superior blade steel with extremely high wear resistance, superior corrosion resistance, high compressive strength, and excellent dimensional stability that retains size and form under heavy use. The FirstEdge Elite Field Knife is equipped with a Kydex Tri-Composite Knife Sheath (patent pending).

KYDEX Tri-Composite Sheath:

The FirstEdge Fixed Blade Tri-Composite Knife Sheath (patent pending) is constructed of precision-formed KYDEX panels, with two hardened stainless steel liners in between. This design allows for disassembly, cleaning, and reassembly in minutes. The panels are fastened with hard-coated stainless steel Hex fasteners. Compartments and drain holes ensure moisture absorbance and sand grit retention is minimal. Knives snap securely into the KYDEX Sheath and are removed with positive thumb pressure, ensuring safe carry and rapid and safe deployment. The sheaths withstand hard conditions in the field.

FirstEdge is proud to offer ELMAX Steel in our premium knife products. Produced by Bohler-Uddenholm of Sweden, ELMAX is “High Chromium-Vanadium-Molybdenum” alloyed steel, made of 18% Chromium, 3% Vanadium, 1.7% Carbon, 1% Molybdenum, 0.8%Silicon, and 0.3% Manganese. This composition of metals results in a superior stainless steel alloy with high wear resistance, superior corrosion resistance, and high compressive strength. The ELMAX advance powder metallurgy technology allows for these rare performance capabilities. The steel is hardened to 60-61 HRC, resulting in excellent edge retention and high impact resistance. It is easily sharpened and holds an edge as well as carbon steel alloy.

Comparative testing of ELMAX versus other stainless steels show superior performance by ELMAX. Other steels may perform in one aspect, but are weaker in others: tough but difficult to sharpen; sharp but prone to corrosion and rust; rust-resistant but a softer blade. ELMAX performs without trade-offs. Using the industry standard, CATRA (Cutlery Allied Trades Research Association), Edge Retention Test, ELMAX scored higher than other stainless steels at 62 HRC. In the TCC (Total Cards Cut) Test that measures the number of silica impregnated cards that a knife can cut at one time, ELMAX placed second with 930.7. ELMAX steel at 61 HRC performed better than other stainless blade steels, even those at 57 HRC, despite the fact that a lower HRC has been viewed as stronger.

ELMAX steel is ideal for Survival, Outdoor and Underwater applications where high durability, toughness, and corrosion resistance are critical. ELMAX knives withstand extended exposure to moisture, extreme temperature change, and constant heavy use. Other applications include Hunting, Fishing, and Food Service where sharpness and ease of sharpening and robustness are critical features.
