The Trapperlock is born from the legendary Trapper but with one blade and one-hand opening performance incorporated by a thumb stud. The engraved thumb stud is fixed by a torque screw allowing for better control and the liner lock enables the one-hand opening performance. The Trapperlock holds a clip blade which is commonly used as a multi-purpose blade and preferred for detail work. This knife is constructed with our 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 resharpening. However, they are less resistant to rusting, pitting and discoloration than stainless steel.
