Ka-Bar Coytu AUS 8A Folding Knife - Black

A folding knife designed for rescue operations and everyday use, opened using a Flipper. The Drop-Point blade is made of AUS 8A stainless steel, and the black handle is made of GFN (Glass-Filled Nylon). The knife is equipped with a Crossbar Lock, a glass breaker, and a seatbelt cutter.

AUS 8A steel blade

The blade is made of AUS 8A stainless steel, which offers good corrosion resistance and is easy to sharpen. The material is characterized by a good balance of strength, wear resistance, and cutting edge durability, making it ideal for everyday use.

Drop point blade with black finish

The Drop-Point blade, with a smooth cutting edge, was flat-ground and coated with a black protective coating that increases scratch resistance. The jimping on the spine of the blade provides a secure thumb rest, improving control over the knife while working.

Ergonomic GFN handle, glass breaker, and belt cutter

The handle is made of GFN (Glass-Filled Nylon), which is resistant to moisture, mechanical damage, and changing weather conditions. The ergonomic profile and non-slip surface ensure a secure grip during use, while the adjustable metal clip allows for convenient carrying of the knife. At the end of the handle, there is a glass breaker and a seatbelt cutter, useful during rescue operations.

Crossbar lock and flipper

The knife is equipped with a Crossbar Lock, which effectively prevents the blade from accidentally folding while in use. Opening it with the Flipper allows for quick deployment of the blade, and the mechanism’s design enables convenient one-handed operation.

Ka-Bar


Militaria.pl is a premium dealer of Ka-Bar.


Ka-Bar is a brand whose history dates back to the late 19th century, and which gained real fame during World War II, when the Fighting Utility model was officially adopted by the US Marine Corps. The durable and versatile knife quickly became legendary, proving itself both in combat and in the daily tasks of soldiers. The name Ka-Bar itself comes from the 1920s, when a trapper described in a letter how he managed to “kill a bear” with a Union Cutlery knife. In 1952, wanting to emphasize the power of this symbol, the company officially changed its name to Ka-Bar Knives Inc., and its products are still considered a model of reliability today. An important chapter in the brand's history is also its collaboration with Ethan Becker, which resulted in the Becker series, highly valued by users, combining practical solutions with a modern approach to knife design.

AUS-8A feature
AUS-8A
AUS-8A is a Japanese stainless steel, equivalent to 440B steel, characterized by a good balance between corrosion resistance, ease of sharpening, and edge retention. The carbon content (0.7-0.75%) affects the hardness of the steel, while chromium (13-14.5%) provides very good corrosion and abrasion resistance. Vanadium additives (up to 0.26%) improve the homogeneity of the steel's crystal structure and increase the blade's resistance to abrasion. The steel also contains molybdenum (0.1-0.3%), manganese (0.5%), silicon (0.4-1%), and nickel (0.49%). After proper heat treatment, AUS-8 steel achieves a hardness of 58-60 HRC, making it a solid material with good cutting properties and durability. The steel is widely used in mid-range knives, mainly produced in Japan and Taiwan, such as the popular Ontario RAT 1.
Crossbar Lock feature
Crossbar Lock
Crossbar Lock is the general name of the mechanism used after the Benchmade patent expired in 2018. The design works on the same principle as the Axis Lock - a spring bar moves along the handle and locks the blade in the open position. The differences between manufacturers mainly concern the details of workmanship, materials, and the shape of the switches. The lock is double-sided, easy to use, and extremely popular in modern EDC knives. Thanks to its versatility, it has become the standard for many companies.
GFN - Glass Filled Nylon feature
GFN - Glass Filled Nylon

GFN (Glass Filled Nylon) is a nylon reinforced with glass fiber, offering low weight, high durability, and resistance to moisture and many chemicals. The material performs exceptionally well in demanding conditions, maintaining its strength even under intensive use. GFN surfaces may be completely smooth or textured to improve grip, providing better control and overall ergonomics. The robustness of GFN handles has made this material a standard in the production of EDC (Everyday Carry) knives as well as lightweight tactical designs.
