This is the most sharp and strongest replacement razor knife available, with blades that change easily and safely by pressing a button. The black oxide coated blade holder supports the razor blade for the strength of a standard knife and the sharpness of a surgeon scalpel. The 3.5" Japanese 420J2 stainless steel razor blades are heat-treated with precision and hand-finished. TPR rubber grips are mounted on robust stainless steel linings for unmatched resistance and anti-slip grip even when wet. Available with a black handle and black nylon case or a bright orange handle with Mossy Oak® camouflage case. The bright orange handle is easy to spot on the ground, which saves valuable time on the ground while avoiding losses. Complete supplied with six spare blades. Replacement packages of 6 blades are sold separately.
