These amazing ESEE knives are made from high carbon 1095 steel. And while 1095 is a top choice for professional cutlery designed for hard use, it will rust and stain if not properly cared for, especially on the cutting edge and around the laser engraving. It is the user's responsibility to keep the blades properly lubricated and cleaned. ESEE Knives suggest using a dry film rust inhibitor such as TUF-GLIDE or TUF-CLOTH. The ESEE-3P-MB-DE includes a black molded sheath, boot clip, paracord, cord lock and Cordura MOLLE back. The ESEE-3P-MB-DE fixed blade knife features a dark earth finished 1095 steel blade with a plain cutting edge, Micarta scales and a standard breaker pommel. Made in U.S.A
