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 resharpening. However, 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.
