Blue bone knives have stainless steel blades that get the job done and their classic blue handles look even better the longer you carry them. The CopperLock® knife is an original design by W.R. CASE that combines elements from the Trapper and Copperhead to make a new lockback knife. The mini CopperLock® is smaller than the traditional CopperLock® without compromising durability. With a fully locking clip blade, this mini CopperLock® knife has the cutting power of a lockback, with the look and feel of a traditional CASE pocket knife. The clip blade is commonly used as a multi-purpose blade that makes this pocket knife great for everyday use. This knife is constructed with CASE Tru-Sharp™ stainless steel which is a special high-carbon steel that helps the blades hold an edge longer than conventional steel. It also offers extraordinary blade strength and corrosion resistance.
