Extrema Ratio N.K.1 Neck Knife Black N690 (04.1000.0123/BLK)

N.K.1 Black is a solid neck knife with a monolithic design, made from a single piece of Böhler N690 steel. The wide blade has an excellent cutting edge-to-blade length ratio, making it perfect for cutting. The blade's back has a hollow for precise thumb or index finger operation, which increases control during precision work. The kydex sheath offers multi-position attachment, allowing the knife to be worn around the neck with the included paracord or attached to the MOLLE system on tactical equipment. Thanks to its compact size and well-thought-out design, the N.K.1 is perfect for both tactical and everyday tasks, offering reliability and functionality in any situation.
