Cold Steel Koga SD1 7.5" Black Polymer Self-Defense Impact Tool

The Cold Steel Koga SD1 is a compact self-defense impact tool inspired by traditional Koga Ryu stick fighting techniques. Built from high-impact polymer (structural nylon) in a black finish, this 7.5" personal protection tool delivers impressive strength and durability without the weight of steel.

At just 4.1 oz, the Koga SD1 is easy to carry and deploy, yet substantial enough to provide leverage for restraints, joint locks, and submission holds. Its 7.5" overall length and approximately 1.2" diameter make it a versatile impact tool for personal protection and martial arts applications.

Manufactured in Taiwan to Cold Steel's exacting standards, the Koga SD1 offers a practical, lightweight solution for everyday self-defense. The all-polymer construction keeps the tool light in the hand while still providing the mass needed for effective impact.
