The North Mountain Blade CHOP 4 (2412-ORCF) is part of the brand’s flagship front-flipper lineup — the series that helped spark the front flipper trend in Asia, with over 50,000 units sold. Designed with a pure, functional aesthetic, the CHOP 4 blends Japanese blade craftsmanship with modern precision machining.
At the core is a 3.5" Japanese-style tanto blade, forged from SLD-Magic Japanese steel in a beautiful three-layer San Mai construction. The visible hamon wave line showcases traditional forging methods while delivering outstanding edge retention (60–61 HRC), toughness, and cutting performance.
The Orange Ceramic Carbon Fiber handle adds a bold, high-visibility aesthetic without sacrificing strength or lightness. Combined with a front flipper mechanism on ceramic bearings, deployment is crisp, controlled, and fast — making it ideal for enthusiasts who value refined action.
The 2412-ORCF is a statement piece: elegant, vibrant, and built for performance. Whether you’re a collector or an EDC aficionado, this knife offers a unique blend of heritage steel and modern design.
