'65 Collection Karsumba S
Description
The Karsumba S is a tribute to the adaptability of those who were thrown into unfamiliar battles and learned to thrive. Inspired by traditional karambit design but reimagined without the ring for tighter carry and faster deployment, it’s a blade that reflects the close-quarters intensity of a chaotic era. The OD green KG Gunkote finish guards the CPM M4 steel against the elements, and the ironwood handle brings natural durability with a timeless feel. It’s built for speed, instinct, and survival, no matter where you’re dropped.
There’s no flash here, just raw function honed into an edge. The Karsumba S cuts through hesitation, just as those it pays tribute to cut through fear with instinct and clarity. It’s compact, curved, and lethal when it needs to be like the fast, silent movements of a soldier who’s learned that efficiency is everything. Whether concealed on a belt or gripped in tension, this blade is for those who don’t wait for orders, they move when it matters.
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.
