High quality, extremely collectible handmade knives since the 1800s.
SHOP CASE KNIVESThe Case XX Diamond Series Blue and Purple Corelon Two-Blade Copperhead blends timeless American craftsmanship with bold, modern color. Designed for those who appreciate a fine balance between everyday utility and striking presentation, this knife carries the dependable quality that’s made Case XX a household name for generations. It’s equipped with two mirror-polished Tru-Sharp surgical steel blades—a Wharncliffe and a pen—both precision-ground for superior cutting performance and corrosion resistance. Traditional nail nicks make for smooth, reliable opening, while the Copperhead frame provides a secure, comfortable grip in hand.
The handles are a vibrant mix of blue and purple Corelon, swirled together in a finish that catches the light and draws the eye. Each piece of Corelon is unique, giving every knife its own distinctive look. Brass pins and liners add durability and structural integrity, while the nickel silver bolsters bring a classic touch that ties it all together. Measuring 3.87 inches closed and weighing 3.8 ounces, it’s sized perfectly for pocket carry—ready for daily use yet refined enough for display.
This knife represents the artistry and precision that define Case XX, one of America’s oldest and most respected cutlery makers. Proudly made in the USA, the Diamond Series Copperhead reflects both heritage and innovation in one smooth, reliable package built to last.
