The ultimate double-blade knife for big game with our patented replacement razor-blade knife on one side, plus gutting blade on the other to open game like a zipper. This is the sharpest, strongest, replacement razor-knife available with blades that change safely and easily at the push of a button. The black-oxide coated blade holder supports the razor-blade for the strength of a standard knife and sharpness of a surgeons scalpel. Our signature gutting blade cuts underneath the skin without cutting hair, or piercing internal organs that can spoil fresh game meat. Both blades open and close independently with one hand and lock securely. The Razor-Pro comes complete with six 3.5 Inch Japanese 420J2 stainless replacement blades and a nylon sheath with pockets to hold both the knife and spare blades. Replacement packs of 6 blades are sold separately.
