Blade construction and cutting performance

The hollow-ground bevels on the San Mai tantos create a fine, acute edge geometry that slices efficiently while the thick tanto point preserves strength for piercing tasks. The satin finish on the bevels helps the blade shed debris and resist surface rust, while the line-grain finish on the flats adds a tactical aesthetic and reduces specular reflection when light hits the blade during low-light operations. These design choices make the knife versatile for both utility tasks and defensive applications.

Handle design and weatherproof reliability

Flattened oval Kraton handle

The flattened oval Kraton handle is a standout feature. Its shape resists rolling and twisting in the hand under hard use, giving predictable control during thrusts, chokes, or rigorous cutting work. Kraton is a rubber-like polymer that won’t crack or rot and is immune to the ravages of bad weather—important for users who operate in wet, humid, or cold conditions. The tactile surface aids positive purchase even when gloved or wet.

Sheath, fitment, and practical considerations

The included Secure-Ex sheath provides quiet carry, secure retention, and fast deployment. For those using the knife in tactical roles, the sheath’s shape and retention method keep the blade accessible without unnecessary slapping or noise.

As a Cold Steel offering in the Knives category and listed under model Various, this tanto balances edge geometry, corrosion-resistant finishes, ergonomic control, and a trusted handle material—making it a solid option for professionals and serious enthusiasts.
