The ESEE-5 was designed by military SERE instructors as a hard-use downed pilot's survival knife. Quality and durability is unquestionable with this fixed blade knife. A canvas Micarta handle ensures a comfortable, sure grip. The textured powder coat finish adds to the durability of this tool. A glass breaker is featured on the handle as well.The carbon steel knives are made from 1095 steel. And while this 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 users 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.
