Toor Knives Unveils Karsumba R in New SOF Colors
Toor Knives has expanded its Karsumba R lineup with two new SOF Series colors: SOCOM Black and Phantom Grey. Designed as a modern take on the traditional Karambit, this fixed-blade knife offers enhanced retention, superior cutting performance, and exceptional durability, making it an ideal tool for self-defense and tactical applications.
A Fighting Blade with Tactical Precision

The Karsumba R stays true to the classic Karambit design, featuring a curved blade and standard handle ring for optimal grip and retention. Originally developed for farming, the Karambit evolved into a formidable combat blade, with its curved shape enhancing cutting power and allowing for stronger, more controlled strokes in defensive scenarios.
Toor Knives has crafted the Karsumba R from CPM M4 steel, a material prized for its toughness, corrosion resistance, and exceptional edge retention. The blade undergoes Toor Knives’ precision heat treatment process, achieving a hardness of approximately 60 Rockwell, ensuring long-lasting sharpness and durability.
Compact, Concealable, and Ready for Action
Measuring just over 6.5 inches overall, the Karsumba R is designed for easy concealment and rapid deployment, making it a trusted option for self-defense professionals, military personnel, and tactical users.
Now available in SOCOM Black and Phantom Grey, the Karsumba R combines stealthy aesthetics with battle-ready performance, further cementing Toor Knives’ reputation for high-quality, purpose-driven blades.
