Caring for your Camillus Knife Thank you for purchasing a Camillus Knife. Our knives are made of the finest cutlery-grade steels and are through-hardened to hold an edge. With proper care, this knife will continue to provide quality cutting performance for an extended period of time. After each use, clean thoroughly with soap and water and immediately towel dry. When knife is fully dry, oil the blade with steel lubricant to prevent rust. Use glass cleaner to clean the knife handle.
