We designed the Karsumba with traditional Karambit knife features like the curved blade, but removed the ring in order to reduce its overall length, making it much easier to conceal. Precision ground out of CPM S35VN steel, the Karsumba has the desirable toughness and edge retention Toor Knives has become known for and is strikingly lethal. The Karsumba features a black oxide finish, and an easy to grip Canvas Micarta handle. Each one is made here in San Diego, CA by our skilled manufacturing team and comes with a black KYDEX® sheath.
