MAC Apnea 9 BE Diving Knife Black Skeleton W 1.4060 (MC APN09-2)

Apnea 9 BE Black Skeleton professional, ultra-light 85 g compact knife for divers, so-called back-up with full tang construction, with a blade for cutting ropes and straps, a slot for unscrewing / tightening shackles and a hole for a cord. Designed for professional and recreational diving. Designed for freedivers, spearfishing enthusiasts and underwater professionals. Made of nitrogen-alloyed W 1.4060 stainless steel, it offers excellent corrosion resistance, durability and cutting performance. The 7-centimeter blade is long enough to cut anything you need underwater without any problems. The blade is equipped with a shaft removal tool - a tool for removing and replacing crossbow bolts used for spearfishing. High-performance blade, comfortable handle and low-profile sheath with secure locking mechanism make the Apnea 9 an indispensable part of any diving expedition.

1.4060 (MA5 / X35Cr16N) - martensitic, nitrogen-bearing stainless steel with high hardness. Conventional stainless steel, MA5 steel (X35Cr16N AFNOR standard / 1.4060 Wnr standard) is similar to X46Cr13 steel. Its main advantage is that it offers excellent corrosion resistance as well as better hardness after heat treatment. Hardness and durability are the characteristics of this universal grade. The heat treatment of MA5 / X35Cr16N / 1.4060 steel allows for high hardness (up to 60 HRC) and at the same time makes it resistant to aggressive marine environments.

Regular maintenance of 1.4060 (MA5 / X35Cr16N) stainless steel prevents deposits and maintains its shine. It also makes it easier to remove spots and tarnish. Cleaning should be done before a visible layer of dirt or fingerprints appear, thus minimizing the risk of permanent discoloration of the steel surface. Do not use any cleaning agents that contain chlorine, salt, acids or bleach.

PTFE Black - polytetrafluoroethylene, which is widely used in the coating industry, is an ultra-fine, low-molecular-weight product that is processed using a special process. It is characterized by excellent chemical, weather and temperature resistance, thermal stability, non-stickiness, electrical insulation, fire resistance and self-lubrication. The use of polytetrafluoroethylene as a coating material on the blades reduces friction during use, thus reducing the amount of force required for all kinds of work. Blades coated with PTFE have been shown to require 22% less average force and 26% less maximum force compared to blades coated with chrome.

Blade - Dagger type, sharpened on both sides with excellent cutting properties, finished with a flat grind. One blade completely smooth Plain, the other completely serrated Serrated with a smooth blade a few millimeters long at the tip. The unique serrated blade consists of one large and two small teeth, alternately arranged, the so-called two-step. This pattern increases the length of the cutting edge by up to 24% compared to a smooth blade. Ideal for aggressive cutting of hard materials, plastics and fibrous materials such as ropes or nets. The notched blade can be used to lever open nails or screws under water. The blade has a black PTFE (polytetrafluoroethylene) protective coating. The blade should be cleaned in fresh water and oiled after each use.

Handle - extension of the blade. For better grip, the edges are rounded and the area around the guard is covered with jimping. The steel crossguard and ergonomic shape of the grips prevent the hand from slipping while working on the blade.

Sheath - made of hard PP polymer with holes for water and moisture drainage. The sheath is equipped with a latch to prevent the knife from slipping out in the water. Two rubber straps and 2 plastic buckles are included with the sheath to allow it to be attached to the shoulder, lower leg or vest.
