Case's combination of Dark Red Bone grips with carbon steel blades has been essential to the Case line for years. This new series features their Peach Seed jigged handle style; a new twist to an ageless favorite. The Medium Jackknife is a pattern where the blade or blades open from one end of the knife. This knife features two blades, the Clip and Pen blades. The Clip blade is commonly used as a multi-purpose blade and is preferred for detail work. The Pen blade is great for small detailed uses, especially for everyday use such as opening envelopes and boxes. This knife is constructed with Case's Chrome Vanadium (CV) 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. However, they are less resistant to rusting, pitting, and discoloration than stainless steel.
