The North Mountain Blade KAIKEN – Nature Hole Tanto blends classic Japanese tactical design with modern engineering, premium materials, and a sleek stonewashed aesthetic. Built around a high-performance 3.5" M390 Tanto blade, this folder delivers exceptional edge retention, corrosion resistance, and cutting power.

The blade features a segmented Tanto profile with a hollow-ground main edge for superior slicing efficiency and a flat-ground reinforced Tanto tip for powerful piercing performance. The stonewashed finish enhances durability with a rugged, scratch-resistant appearance.

The titanium handle keeps the knife lightweight, strong, and corrosion-proof. Its surface can be heat-colored at home, allowing users to create a custom anodized look for a personalized finish. Paired with a matching titanium pocket clip, the KAIKEN maintains a premium, fully titanium build.

Equipped with an optimized front flipper, the knife deploys smoothly, safely, and intuitively. This mechanism keeps the knife more secure in the pocket and reduces the chance of accidental opening.

With a balanced 4 oz weight and an 8" overall length, the KAIKEN is a refined tactical tool designed for EDC, outdoor use, or collection-worthy craftsmanship.
