We developed the M311 SPELTER knife in co-operation with members of forward air observation units, close protection teams and special air operations. Other members of the military and security community also contributed to its design. During the knife’s development, we focused on making use of their experience and requirements. Thanks to this unique co-operation, we had the chance to genuinely verify the quality of the chosen materials, design and general construction of the product. The knife was tested over a long period in extreme environments and various climates, including hot, dry and humid parts of Asia, as well as freezing areas beyond the polar circle.
We manufacture its blade from one of the best steels in the world, the Swedish Elmax. This top-quality steel runs throughout the whole body of the knife to the base of the handle, which has a point for breaking glass. The blade has an extremely durable DLC (Diamond-like Carbon) surface finish that minimises reflections, prevents corrosion and gives the steel’s surface great sliding properties. We produce the handle using 3D machining from Micarta, which, thanks to its shape and grooving, sits easily in the hand and gives the knife a sure grip in every situation. The knife is equipped with a safety paracord loop that stops it falling out of your hand when you are cutting. The whole structure is held together by a combination of solid threaded sleeves and four M5 screws, also with a DLC finish. Easy, reliable and safe carrying of the knife is ensured by a self-locking Kydex sheath, which has openings for fixing to a blade-tech system, enabling carrying on both molle and pals tactical webbing. A generous flow opening enables easy and fast maintenance of the sheath. Together with the Kydex sheath, we supply a hanger for easy carrying on the belt.
