Intruder; a fast, long and lean fighting knife. This model Intruder features a satin finish blade and multi-layer blue/black grip. The name of the knife says a lot about it. Kizlyar Supreme has managed to combine aggressiveness, grace and great work properties into this knife. The handle fits the hand well, giving a good grip with the palm. The lower guard does not allow fingers to slip onto the cutting edge even during serious work loads. The flat ground and well-balanced 440C stainless steel blade make this knife reliable in the field with a low maintenance requirement. Light and durable MOLLE compatible Kydex sheath features a highly versatile multi-position platform with a rotatable clip, allowing a variety of carry options; horizontal, vertical and several angled positions are possible.
