The ESEE Candiru Comes with survival kit that includes: ParaCord, Cord Lock, Large Split Ring, Small Split Ring, Ferro Fire Starting Rod, Emergency Whistle, Plastic Snap Hook, and Clip Plate Kit. Our carbon steel knives are made from 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. We suggest using a dry film rust inhibitor such as TUF-GLIDE or TUF-CLOTH.
