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.
