Camillus 8" Shatter Folding Knife with Glass Filled Nylon Handle and AUS-8 Steel. AUS-8 offers exceptional balance between toughness, edge sharpness, and corrosion resistance. The steel is bonded with Carbonitride Titanium that resists rust and corrosion and is up to 10x harder than untreated steel so the blade stays sharper, longer. The handle is Glass Filled Nylon, a material that is used in many of our knives. We add glass-filled materials to polypropylene, ABS and other substrates in order to provide the strongest, most rigid handles. Liner Lock & Pocket Clip. Lifetime Warranty.
