Cold Steel Double Agent I Serrated Knife

Neck knife built with a robust Full Tang construction, equipped with a blade featuring a Hawkbill profile inspired by Karambit-style knives, crafted from premium AUS-8A stainless steel. The handle utilizes Grivory material and offers a textured, non-slip surface for optimal grip security. The package includes a Secure-Ex system sheath, along with a ball chain for convenient neck carry.

Double Agent represents a range of ultralight knives conceptualized by Zach Whitson, a seasoned instructor and founder of the Counterpoint Tactical System, rooted in Filipino martial arts.

AUS-8A Japanese stainless steel

Forged from Japanese AUS-8A stainless steel, the blade offers an optimal blend of corrosion resistance, edge retention, and sharpening convenience. Expert heat treatment achieves a hardness rating of 58–60 HRC.

Hawkbill profile blade with a serrated cutting edge

The blade features a Hawkbill profile with a length of 76 mm and a thickness of 2.3 mm, equipped with a serrated cutting edge crafted using a flat grind. Outstanding cutting performance is ensured, particularly when tackling fibrous materials. A satin polished finish delivers a semi-matte appearance, boosting visual appeal and offering increased resistance to scratches. The specialized blade geometry merges the versatility of the Hawkbill shape with the aggressive styling found in Karambit-inspired designs.

Grivory material scales, two finger holes

The handle features an ergonomic shape and is covered with Grivory material, renowned for its resistance to impacts and abrasion. A key aspect of the design is the inclusion of two finger holes, enhancing grip security and preventing the hand from slipping onto the blade. Together with jimping on the spine of the blade, these features deliver excellent knife control, even in wet or dirty conditions.

Secure-Ex sheath, chain for neck carrying

The knife comes with a sheath designed in the Secure-Ex system, constructed from a material that is both lightweight and highly durable, as well as resistant to various weather conditions. Multiple holes in the sheath allow for easy cord threading, while its design ensures the knife remains securely fastened, minimizing any risk of accidental loss. The addition of the ball chain enables the knife to be worn comfortably around the neck, providing both practicality and ease of access for everyday carry.

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.
Grivory feature
Grivory
Grivory is a modern glass fiber reinforced polyamide used in knife handles. It is characterized by high resistance to impact, abrasion, and chemicals, as well as stability in temperature fluctuations and contact with moisture. It retains its dimensional stability even with intensive use, making it a practical solution for EDC knives and outdoor models. Grivory handles are sturdy, lightweight, and comfortable to use, making the material popular among manufacturers who value reliability and modernity.
