The Ninja Mass Grave Throwing Target Knives are constructed of stainless steel with half the set having a red heat tempered finish and the other half having a black anodize finish. On each blade there are skulls from a mass grave depicted in either red or black. Several holes are cut out of the handle making each knife lighter, balanced, and aerodynamic. In this set you get a complete set of 12 knives with a nylon sheath.  This sheath has individual pockets for each knife and adjustable straps on the back.  On the end of the sheath is an extra pocket for carrying smaller items like a small sharpening stone for instances.
