Karsumba R - SOCOM Black

Introducing the Karsumba R, our version of the traditional Karambit knife featuring a curved blade and standard ring for ease of drawing and utility. Now in new SOF Series colors!

The Karsumba R is a traditional take on the karambit fighting knife. The addition of the handle ring allows for increased retention in knife fighting scenarios. Though original Karambit knives were much longer and originally intended for farming practices, the shortened fighting version has proven beneficial in the biomechanics of the blade allowing for stronger and more lethal cutting strokes. The karambit fighting knife is the perfect blade for self defense and tactical applications. 

This blade is precision ground out of CPM M4 steel, giving it the desirable toughness and edge retention Toor Knives has become known for, and is strikingly lethal. CPM M4 is known for its corrosion resistance and edge retention which is supported by the Toor Knives heat treatment process, leaving this blade right at about 60 Rockwell hard. This blade sits at a little over 6.5” overall and is the perfect concealable self-defense blade.

Each one is made here in San Diego, CA by our skilled manufacturing team and comes with a KYDEX® sheath.
