Cold Steel CS17TS Kobun 5.5" Fixed Tanto Serrated Blade

The Cold Steel CS17TS Kobun delivers reliable cutting performance with its 5.5-inch serrated tanto blade and tactical-grade construction. This fixed blade knife combines Japanese-inspired design with modern materials for versatile field applications.

What Makes This Different

The Kobun features an AUS-8A stainless steel blade with tanto geometry and aggressive serrations that cut through rope, webbing, and fibrous materials more efficiently than plain edges. The full tang construction extends through the entire Kray-Ex handle, providing structural integrity that outlasts partial tang designs. Cold Steel's heat treatment process brings the AUS-8A steel to 59-60 HRC for optimal edge retention and corrosion resistance.

Key Features

• 5.5-inch AUS-8A stainless steel tanto blade with serrated edge
• Full tang construction for maximum strength and durability
• Black checkered Kray-Ex handle provides secure grip in wet conditions
• Tanto point geometry penetrates tough materials effectively
• Includes Cor-Ex sheath with belt loop attachment
• Overall length of 10.5 inches with 4.75-inch handle
• Blade thickness of 0.25 inches for heavy-duty applications

Field testing demonstrates the serrated edge's effectiveness on synthetic materials, paracord, and vegetation while the tanto point maintains structural integrity under lateral stress. The Kray-Ex handle material resists temperature extremes and chemical exposure, making this knife suitable for marine environments, tactical applications, and outdoor work. The checkered texture pattern ensures positive grip retention even when wearing gloves.
