Each knife is constructed of a single piece of steel and protected with a black anodized finish. The edges of these blades have been heat treated to create the unique colors you see here. Weight reducing cutouts run the length of the blade and handle to balance each piece. A decorative cord to match each blade is weaved in a fun pattern on the handles. Well balance and ready for fun this set can’t be beat. Included to transport your knives is a black nylon sheath with belt loop.
