The North Mountain Blade CHOP 4 (2412-WHCF) represents the perfect fusion of Japanese blade heritage and modern front flipper design. Built with premium SLD San Mai steel, this folding knife delivers exceptional edge retention, toughness, and cutting power—ideal for enthusiasts, collectors, and everyday carriers alike.
The 3.5-inch Japanese-style tanto blade excels at piercing and controlled slicing. Crafted from SLD San Mai steel, it features a distinct hamon line that showcases the layered construction. The blade’s clean grind lines and traditional profile give it both visual appeal and practical versatility.
The handle is made from white ceramic carbon fiber, providing an ultra-lightweight yet rigid structure with striking aesthetics. The smooth contours and front flipper mechanism offer a fast, clean deployment that feels as refined as it looks. A ceramic ball bearing pivot ensures buttery-smooth action, while the secure liner lock keeps the blade firmly in place during use.
Compact, elegant, and performance-driven, the CHOP 4 is a standout piece in the North Mountain Blade lineup—blending traditional Japanese blade influence with modern tactical precision.
