Description

HK124503: FX03 Fixed Blade

HK Knives

The Heckler & Koch FX03 is a sub-compact fixed blade knife, engineered to meet the demands of modern military and law-enforcement users, built from premium, purpose-driven materials. Its strong yet highly effective tanto blade is forged from powder-metallurgical MagnaCut, which is a steel that balances edge retention, toughness, and corrosion resistance by dissolving a carefully calculated ~10% chromium into a fine microstructure and then finished with a black coating to eliminate reflection. An offset handle and pronounced thumb guard channel power and control to the cutting edge while maximizing user safety during hard use.

Every ergonomic detail supports duty-ready reliability: bolted handle scales of tough fiber-reinforced nylon (FRN) carry HK’s textured pattern for secure purchase, and the flat, slim, one-piece folded Kydex sheath provides a secure, low-profile carry with rapid access (no extra lock required). A spring-steel clip lets you mount the sheath on harnesses, clothing pockets, or the inner waistband, and multiple eyelets accept common attachment adapters (Tek-Lok, IWB belt loop, etc.), making the FX03 a compact, tough, and versatile tool for operational carry.

Perfect size for EDC pocket carry
This German made magnacut Boker is my new favorite EDC pocket carry. Not to mention HK put their stamp of approval on it. So this is the perfect compliment to my CC9 or VPSK EDC. The full tang magnacut blade and finish has held up well to everyday real life tasks of breaking down boxes and opening packages and what not. I've even used the front part of the tanto blade to scrape some caulking out of a tub surround! I'm not at all concerned about blade durability. The handle is a little small but fits my large glove sized hands perfectly fine. The pocket clip is adjustable so you can go with a high carry for more handle grip when drawing or a deep carry for more concealability. The clip has firmly held in pockets of both jeans and carhartt work pants. The sheath has a flared entry for easy sheathing. And since the flare is on the spine side of the knife, I've found it useful to place my thumb on the it when drawing the knife. My only complaint would be the material of the handles themselves. But that's more of a preference than a flaw. Especially at this price point. All in all good buy for the money!
