劍 KAIKEN: The Fourth Sword of the Samurai
Usually, Japanese samurai swords include the Katana, Wakizashi, and Tanto; the smallest, the Kaiken, remains lesser known to the general public. Together, they represent four distinct forms of the traditional samurai blade.
This classic Japanese tactical folding knife merges traditional design with modern functionality. The segmented Tanto-style blade is crafted from premium 14C28N three-layer steel with a hardness reaching up to 60-61 HRC, utilizing classic NorthMountain hand-hot forging technology to create authentic blade surface ripples. The main edge features a hollow grind for exceptional slicing performance, paired with a flat-ground Tanto tip built for powerful piercing capability.
Equipped with an optimized front flipper mechanism, it offers smooth, effortless deployment while sitting securely inside your pocket to prevent accidental opening.
