The Camillus 7.5″ Inflame Carbonitride Titanium Folding Knife is one of Camillus’ champions of versatility. Made with 440 Steel, the blade strikes a terrific balance between hardness and corrosion resistance. The blade’s steel is also bonded with Carbonitride Titanium that provides an added layer of resistance to rust and corrosion while making it up to 10x harder than untreated steel.
