FirstEdge™ Folding Knives were designed in partnership with U.S. Special Forces and are currently used in training and deployment.  The knives are equipped with the FirstEdge™ TrackLock™ Locking Mechanism (patent pending). The TrackLockTM allows for fast and safe one-handed opening and closing of the folding blade with notable ease.  FirstEdge™ Folding 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.

FirstEdge™ Folding Knives are equipped with a patent pending Locking Mechanism designed for military and outdoor extreme environments and applications. The TrackLock’s™ large steel locking pin passes through the blade and hardened steel liners. This “double-shear” mechanism creates one of the strongest possible locks, having passed the industrial standard for knife-lock failure. The TrackLockTM allows for fast and safe one-handed opening and closing of the folding blade with notable ease.


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.
