Camillus CUDA SARKIS 9" Folding Knife with Cuda Open Technology and 3.5" AUS-8 Steel Blade. The combination of these two materials allows the handle to be rugged and lightweight, while also providing an excellent grip in all conditions. 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. An extremely durable ergonomic handle incorporates the Cuda Open Technology. Lifetime Warranty.
