Naifu S is an arm knife designed with an ergonomic shape to ensure comfort and practicality during freediving and spearfishing activities.

Blade Technical Features

The blade, 66.5 mm long, is made from AISI420B stainless steel, known for its combination of strength and hardness. The blade is extremely sharp and includes an integrated line cutter. Its internal structure extends along the entire length of the handle, ensuring optimal rigidity and greater reliability in the water.

The blade heat treatment involves vacuum hardening at 1020°C, followed by nitrogen cooling at 20 atm, to improve hardness and mechanical strength.

Handle and Sheath

The handle and sheath are made from recyclable POM acetal resin, a plastic material characterized by high rigidity, low moisture absorption, and anti-friction properties, ideal for use in underwater environments.

The knife measures 144 mm in overall length, ideal for ensuring control and safety. The locking system uses a central retaining tooth that makes both fastening and release easier, improving practicality and speed of extraction during the dive.
