The Heckler & Koch FX01 is designed as an uncompromising all-steel knife of medium size in skeletonized construction. The design allows full functionality with unrivaled robustness and flatness at the same time. In this way, the knife can be carried openly, for example on a Molle harness, or concealed and does not interfere with everyday movements in civilian or law enforcement situations. The tanto blade made of edge-retention D2 steel enables a wide range of applications such as cutting and scraping. A black titanium coating protects against reflection. The flat, moisture-resistant Kydex sheath can be carried on the harness, in one's clothing pocket or in the inner waistband using the spring steel clip included in the scope of delivery. The eyelets also allow other common attachment adapters (Tek-Lok, IWB belt loop etc.) to be fitted.
