Cold Steel OSS AUS-8A Fixed Blade Knife

A Full Tang-style knife with a double-edged blade. The Bowie-profile blade is made of AUS-8A stainless steel, which offers a balance between corrosion resistance, ease of sharpening, and edge retention. The handle is made of Kray-Ex with a non-slip texture. The set includes a sheath featuring the Secure-Ex system, which allows for multi-position attachment to a belt or other piece of gear.

AUS-8A stainless steel

The blade is made of Japanese AUS-8A stainless steel, which offers well-balanced properties. It is characterized by high corrosion resistance, good toughness, and ease of sharpening, which facilitates quick restoration of sharpness. After proper heat treatment, the steel typically reaches 58–60 HRC, which translates to good cutting performance and durability.

Blade with Bowie profile

The Bowie-style blade is 210 mm long and 4.7 mm thick. The smooth, double-edged blade has a satin finish, which leaves an even, linear pattern and reduces glare on the blade's surface.

Kray-Ex handle

The handle is injection-molded as a single, integrated piece of Kray-Ex. The front cross guard protects the hand and reduces the risk of fingers slipping toward the blade. An additional, smaller cross guard (sub-hilt) provides a second point of support, helping to maintain a steady hand position while working. This design improves durability while also enhancing control of the knife in the hand. The non-slip texture makes it easier to maintain a stable grip, even in adverse weather conditions. At the end of the handle is a hole for a safety lanyard.

Secure-Ex sheath

The set includes a Secure-Ex sheath. It features a detachable loop, allowing you to unclip it and attach it to your belt without having to remove the knife. Additional holes along the edges allow for multi-position mounting of the sheath to various types of gear.

features and technologies

Secure-Ex

Secure-Ex is a high-quality plastic used by Cold Steel to manufacture sheaths and knife cases. This material is characterized by exceptional durability, resistance to mechanical damage, and weather conditions, which makes it an ideal choice for products intended for intensive use. It protects the blade from corrosion and mechanical damage.

Kray-Ex

Kray-Ex is a synthetic polymer with a rubber-like structure used by Cold Steel to manufacture knife handles. It is characterized by high adhesion and anti-slip properties, ensuring a secure grip even in high humidity, low temperatures, and with dirty hands. The material is flexible and absorbs shocks well, which increases comfort of use. Kray-Ex is also resistant to cracking, abrasion, chemicals, and adverse weather conditions, making handles made of this material durable and virtually maintenance-free. Cold Steel uses it in tactical, survival, and utility knives.

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.

Satin

Satin finishing is one of the most popular blade finishes, achieved by grinding the steel with fine-grained abrasives. Parallel micro-scratches remain on the surface, giving the knife a technical, matte appearance. Satin finishing has both aesthetic and practical significance - a smoothed blade is easier to clean, and the slightly reduced friction promotes smoother cutting. Depending on the direction and intensity of polishing, different effects are achieved - from a matte finish to an almost mirror-like finish. Satin is valued in both utility and collector's knives because it emphasizes the structure and quality of the steel while maintaining functionality.

Review for model:

A great knife that really makes a very good impression. The large blade looks excellent and is really solid. The handle fit my hand perfectly and it is very comfortable to hold. The double-edged blade is very sharp, and right from the start you can see that the knife is well made. Overall, I am very satisfied with the purchase and it is exactly what I was looking for.

Review for model:

This is my second Cold Steel knife. The knife is solid. Very sharp on both sides. Secure grip. The tip of the blade is so 'pointy' that it could break when piercing hard material. The knife is hard to remove from the sheath. Despite everything, it's hard to find a better combat knife. Rating: -5.

Review for model:

A real piece of knife, the double-edged blade is perfectly sharpened so you have to be careful, solid construction. The large grip will not be a problem even for large hands. Good sheath, the knife fits in with quite a bit of resistance and there is a bit of a problem when removing it, but it won't fall out when carried tip-down. The only thing that spoils it a bit is the word CHINA next to the Cold Steel logo, but it's just a label. Ordered with in-store pickup in Łódź without any problems, so I recommend both the "knife" and the store.
