Cold Steel Secret Edge AUS-8A Fixed Blade Knife

A neck knife with a fixed Spear-Point blade, inspired by classic Scottish Skean Dhu knives. Crafted from high-quality AUS-8A stainless steel with a satin finish. The model features a lightweight and flat design, ensuring comfort during everyday carry. The set includes a Secure-Ex sheath with a ball chain, allowing the knife to be carried comfortably around the neck.

japanese AUS-8A stainless steel

The blade is made of Japanese AUS-8A steel, which retains its sharpness for a long time and is easy to resharpen. After heat treatment, it achieves a hardness of 58–60 HRC, making it a robust material with good cutting performance, durability, and corrosion resistance.

Spear-Point profile blade, satin finish method

The blade, with a Spear-Point profile, is 89 mm long and 2.5 mm thick. It features a smooth edge that has been ground with a full flat grind. This geometry, combined with the blade’s slim profile, ensures very good cutting performance and allows for precise work while maintaining full control during cuts. The knife is finished with a satin finish, which gives the steel a semi-matte surface, ensuring an aesthetic appearance and increasing scratch resistance. The spine of the blade features jimping that allows the thumb to rest securely.

Griv-Ex handle

The robust black handle is crafted from high-quality Griv-Ex material, renowned for its exceptional resistance to mechanical damage, moisture, and harsh environmental conditions. Featuring a non-slip texture, the handle guarantees a secure and reliable grip during tool operation, while integrated openings help minimize the overall weight of the knife.

Secure-Ex sheath

The set includes a Secure-Ex sheath, designed to hold the knife securely in place while allowing for quick draw when needed. It is equipped with a ball chain that allows you to comfortably wear the knife around your neck. This carrying method is ideal for everyday use as well as for outdoor, tactical, or survival applications.

Secure-Ex feature
Secure-Ex
Secure-Ex is a system developed by Cold Steel, designed for the safe storage and convenient carrying of knives and tools. Sheaths made with this technology are lightweight, durable, and weather-resistant, making them suitable even for intensive use. They hold the knife securely in the sheath while allowing for quick and smooth draw. The system has a modular design - the sheaths can be supplemented with various fasteners, such as buckles, clips (e.g., C-Clip) or ball chains. This allows the knife to be worn on a belt, around the neck, or in other configurations, according to the user's preferences.
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.
Satin feature
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.
Griv-Ex feature
Griv-Ex
Griv-Ex is a durable glass-nylon composite reinforced with fiberglass used by Cold Steel, mainly for the production of knife handles, and in some models also for blade components. The material has a textured surface on the handles, which ensures a secure, non-slip grip, and its maintenance usually boils down to simple washing under running water. Griv-Ex is distinguished by its resistance to moisture, corrosion, mechanical damage, and extreme temperatures, and does not warp or crack under harsh conditions. When used in the construction of blades, it is additionally stabilized by UV rays and heat, which further increases its durability.
