DPx Gear knows a thing or two about making a badass knife. The brand reshaped what a survival knife can be with its designs called HEST (Hostile Environment Survival Tools).
Our latest Badass Knife of the Week takes the HEST idea to the next level. Meet the HEFT 4 Assault.
The DPx Gear HEFT 4 Assault upgrades the HEST concept and makes the knife bigger, harder, and more versatile. The HEFT, which stands for Hostile Field Environment Field Tool, boasts a truly badass design.
The HEFT 4 Assault features a 3.94-inch blade made from high-performance Lohmann Niolox steel. If you’re unfamiliar with this largely German steel, Niolox is known for its excellent stain-resistance, superb edge retention, and overall durability.

The blade is coated with black satin Titanium Carbo-Nitride (TiCN) PVD coating to remove the blade’s reflective properties. Its blade profile is an understated yet versatile drop point.











Such a simple change as adding a G-10 scale doesn’t seem like much, but it completely transforms the look and feel of the knife. Unlike the full stainless steel handle of the original, the front scale on this model provides a sure grip when wielding the knife.
