The Case Medium Stockman is a part of the Amber Bone CV Family. The Clip and Sheepfoot blade sit on the pocket end while the Pen blade sits on the cap end. The Clip blade is commonly used as a multi-purpose blade and preferred for detail work. The Sheepfoot blade allows for added strength at the point making it great for carving and achieving a clean cut. The Pen blade is great for light work. This knife is constructed with our Chrome Vanadium steel. Some knife lovers will settle for nothing less than Chrome Vanadium blades since this special formula of alloyed steel is the original Case blade steel. Case Chrome Vanadium blades are known for their edge-holding ability and easy re-sharpening they are less resistant to rusting pitting and discoloration than stainless steel. We recommend keeping a thin film of oil on the blade to maintain the finish. This ensures that your knife will be around for future generations to enjoy.
