The North Mountain Blade 2412-Bone CHOP 4 is a refined blend of traditional Japanese blade artistry and modern front flipper design. This model is part of the flagship 2412 series — the knife that helped spark the front flipper movement while staying true to minimalistic, functional design principles.
At its core is a handcrafted Japanese-style tanto blade made from SLD-Magic San Mai steel. Forged in a three-layer construction with a hardened core (60–61 HRC), the blade offers exceptional edge retention, strength, and signature wave-like lamination lines inherent to true San Mai steelwork.
The smooth bone handle provides a natural, elegant feel with a clean and unembellished profile. Paired with a liner lockand front flipper deployment, the 2412-Bone CHOP 4 delivers smooth action, secure lockup, and a timeless aesthetic that’s both collectible and functional.
