Cold Steel Magnum Tanto Fixed Blade Knife (San Mai® III)

The Ultimate Tanto. Built Without Compromise.

The Cold Steel Magnum Tanto is the largest and most formidable member of Cold Steel's renowned Japanese-inspired fixed blade collection. Combining traditional Tanto styling with modern engineering, this premium knife is crafted from legendary San Mai® III laminated stainless steel, delivering exceptional edge retention, toughness and cutting performance.

Its imposing 12-inch blade is considerably thicker than many commercially available knives, giving it outstanding strength and rigidity.

A flat-ground primary edge is complemented by a finely hand-finished secondary chisel-ground bevel, creating the unmistakable blade profile that has made Cold Steel's Tanto series famous worldwide.

The robust full-tang construction is paired with durable G-10 handle scales, providing a secure, comfortable grip even during extended use. Whether displayed as part of a premium collection or appreciated for its exceptional craftsmanship, the Magnum Tanto is a true showcase of Cold Steel's dedication to quality.

Each knife is supplied with a rugged Secure-Ex® sheath, offering excellent protection and convenient carry.
