Introducing the Karsumba S, a streamlined evolution of our karambit-style platform, now featuring a standard blade shape for enhanced versatility and everyday functionality. Available in our signature SOF Series colorways.

The Karsumba S blends the combat-oriented legacy of the karambit with the practical utility of a straight-edge design. The handle ring remains for improved retention and control, especially in high-stress or self-defense situations. While the original karambits were long, curved tools used in agriculture, modern adaptations like the Karsumba S optimize the design for close-quarters use. The standard blade shape offers improved ease of sharpening, better straight-line cutting, and broader utility across a range of tasks from tactical applications to everyday carry needs.

Crafted from high-performance CPM M4 steel, the Karsumba S is built for extreme toughness and edge retention. Our proven heat treatment process locks in a Rockwell hardness of approximately 60, striking the perfect balance of strength and resilience. The blade measures just over 6.5 inches in overall length, offering a compact yet potent self-defense solution.

Each blade is proudly manufactured in San Diego, CA by our expert team and comes equipped with a custom-fit KYDEX sheath for secure carry and rapid deployment.
