Our distinctive Gray Bone with extra Pocket Worn ® finishing and easy-sharpening Carbon Steel blades will make these knives feel like familiar old friends that are always willing to lend an extra hand. 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. With a fully locking Wharncliffe blade, this CopperLock ® knife has the cutting power of a lockback, with the look and feel of a traditional Case pocket knife. The Wharncliffe blade is commonly used as a multi-purpose blade that makes this pocket knife great for everyday use. This knife is fitted with high carbon steel blades known for their high tensile strength, wear resistance, and toughness. Many prefer this steel for its edge retention and ease of re-sharpening. Since these are not stainless steel blades, a thin coat of oil applied on them after each use can help maintain their original finish. Comes conveniently packaged in a box. Made in Bradford, PA, USA from domestic and imported materials.
