Heckler & Koch FX01

'The Heckler & Koch FX01 is a medium‑size, all‑steel knife with a skeletonized design that delivers uncompromising durability and a low profile without sacrificing functionality. It can be carried openly (for example on a MOLLE harness) or concealed, and won’t impede everyday movements in civilian or law‑enforcement situations. The tanto blade is made from high‑wear‑resistant D2 steel for cutting and scraping, and a black titanium coating minimizes reflections. The flat, moisture‑resistant Kydex sheath can be mounted on a harness, carried in a pocket, or worn on the inner waistband with the supplied spring‑steel clip; its eyelets also accept common mounting adapters like Tek‑Lok and IWB belt loops.'
