The ESEE-4 is a top notch survival craft and tactical knife. Durable and dependable, exactly what you need in a good fixed blade knife. Carrying this knife will give you total confidence in your ability to handle any situation. 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 the cutting edge and around the laser engraving. It is the user's responsibility to keep the blades properly lubricated and cleaned.As part of ESSE's continuing commitment to training and outdoor education, the box includes survival, navigation and emergency signaling information printed on the box sleeve.
