The North Mountain Blade CHOP 4 (2412-BLCF) represents the pinnacle of the brand’s folding knife design. As the flagship model that helped ignite the front flipper trend, the CHOP 4 has achieved legendary status in Asia — with over 50,000 units sold — and is now gaining traction among enthusiasts worldwide.
The star of the show is the 3.5" Japanese-style tanto blade, crafted from SLD-Magic Japanese steel in a striking three-layer San Mai construction.
