The handle and the sheath are manufactured in recyclable POM material. This is a very sturdy and auto lubricating material with excellent mechanical properties and low water absorption.

NAIFU has a locking system between the knife and the sheath which makes it for easy extraction and insertion.

The blade of NAIFU S is inserted all the way in the handle making it extremely sturdy.

A very important feature of the NAIFU knives is that the blade is machined to create a razor cutting edge whose geometry greatly increases its cutting and penetrating effect.

The knife is delivered with two rubber straps with stainless steel buckles for use on the arms or legs.
