Extrema Ratio N.K. neck knives

The N.K. line is Extrema Ratio’s neck knife range, with the compact N.K.1 as the entry model and the slightly larger N.K.3 as the sturdier version. There is also a karambit-shaped K version of the N.K.3, with a curved blade for a different grip and cutting technique. You’ll find the range in colours such as black, stonewashed and a desert-coloured Desert Warfare finish.

N.K.1, N.K.3 and the N.K.3 K, three ways to carry a neck knife

The N.K.1 is the smallest and lightest model in the range, ideal if you want to carry a discreet backup knife without it standing out. The N.K.3 is larger and therefore feels more solid in the hand, with a blade that is also suitable for slightly heavier work. Both models are available in stonewashed, black and the desert-coloured Desert Warfare finish.

What makes this line special is the N.K.3 K, a karambit version with a curved blade. That shape calls for a different grip and cutting movement than a straight blade, and is often chosen by people who already have experience with this type of knife. There is also a version of the N.K.3 in the harder Böhler S600 steel.

Every model in this range comes with a light sheath that you wear around your neck on a cord. Curious about more compact knives from Extrema Ratio? Browse our full range of Extrema Ratio knives.
