Description

The design of the handle prevents accidental injury while drawing.

A groove on the back of the blade accommodates for the user’s index finger or thumb, according to wielding style.

Due to its overall construction, the N.K.1 is both capable of offense, through very effective slashing strikes, and useful for minute precision work. The included, rapid- release Kydex sheath comes with a paracord strip for neck carry. Further, it can be attached via MOLLE system to tactical vests or to any of the compatible cordura sheaths from Extrema Ratio. Available but not included: BELT-CLIP (for attaching sheath to a belt), polymer UNDER SHIRT SYSTEM (for concealed carry).

Care

ESSENTIAL ROUTINE MAINTENANCE

Regular maintenance is fundamental to preserving the efficiency, reliability, and lifespan of your product. After each use – especially in the presence of salt water, humidity, mud, or grease residues – rinse with fresh water, dry thoroughly, and apply a suitable lubricant to metal parts and moving mechanisms. Periodically inspect the inside of the sheath, removing sand, dust, or abrasive particles that could damage the blade finish when sheathing or unsheathing.
