This Seahorse Whittler is a part of the Case 6.5 BoneStag Family. The Wharncliffe blade is the blade of choice. This blade is great for cutting and has a finer edge/point for increased control. The pen blade is great for small, detailed uses, especially for everyday use, such as opening envelopes and boxes. The coping blade is similar to a Sheepsfoot blade but with an angled point. It is used for making cuts in tight areas or curved cuts. This blade is popular with carpenters and electricians as it is similar to a coping saw but without the teeth and can be used to scratch lines in wood or other materials. The slip joint pocket knife is constructed with Case Tru-Sharp Stainless Steel, which is a special high-carbon steel that helps the blades hold an edge longer.
