Demko Knife AD20.5 Shark Foot Grey Grivory, Black DLC D2 by Andrew Demko (205-D2-SF-DLC)

AD20.5 Shark Foot Grey Grivory, Black DLC D2, the result of years of work and experience of Andrew Demko, a long-time designer at Cold Steel. A compact folding knife that was designed for the toughest tasks. A real tool, characterized not only by its robustness and power, but also by its unique design. Ergonomic Handle, made of Grivory composite and Blade made of D2, a proven tool steel.One of the most important elements of the knife is its lock.Shark-Lock™ is an innovative mechanism that is considered one of the strongest in the world. Thanks to it, the knife is not only safe to use, but also gives you the confidence that it will stand up to even the toughest tasks. This is an exceptional example of a compact EDC (Every Day Carry) knife, an excellent choice for anyone looking for a reliable everyday tool.

Andrew Demko - owner and founder of Demko Knives, first started forging chisels in 1988, when he was in seventh grade. He immediately realized it was his passion and began forging knives almost immediately. Like many blacksmiths, Andrew began his journey in the garage, honing blade shapes and sharpening them on a small grinder. Andrew's passion for engineering and attention to detail was noticed by the well-known Cold Steel company. At Cold Steel, Andrew developed some of the most innovative and powerful locking mechanisms in the industry. The legendary Tri-Ad Lock, Scorpion Lock, and most recently the one-handed operator's dream - the Shark-Lock.

D2 - a high-carbon, high-chromium high-speed tool steel heat-treated to 58-60 HRC. With a high 13.0% chromium (Cr) content, it offers greater corrosion resistance than most high-carbon steels. Combines strength, excellent edge holding and easy sharpening. Features high wear resistance due to high carbide content in the microstructure.

DLC (Diamond Like Carbon) durability of the blade surface is enhanced with a matte black nanocomposite coating, which exhibits unique properties such as exceptional hardness and low friction, as well as excellent corrosion protection. It is one of the most resistant coatings to scratches and abrasion that are used in the industry, including the knife industry.

The Shark-Lock™ mechanism is located on the back of the knife and is operated by a ramp-like "flipper." When the blade is opened, the spring-driven locking arm moves up and then into a notch in the shank, placing it under the locking pin. Uniquely, the locking mechanism moves forward and backward while simultaneously moving up and down. This allows for an increase in the size of the blade contact area, providing better mechanical strength in a specific area. And since the drive spring that moves the locking element upward to the locked position is located in the locking arm itself, it will not be exposed to dirt and debris.

Blade - Wharncliffe type, coated with black DLC coating. The straight cutting edge converges towards the needle-sharp tip of the knife. The thickness of the blade provides high strength while the high, flat grind gives excellent cutting edge geometry and extreme cutting performance. Ball bearings support the opening of the blade with either a dual thumb stud in the blade (dual thumb stud) or an oval hole (thumb hole). The entire blade is locked with what is considered the world's strongest Shark-Lock™.

Handle - Grivory grips, a virtually indestructible plastic that is insensitive to weather conditions, resistant to chemicals and mechanical damage. The chamfered edges of the covers eliminate sharp edges and the characteristic textured surface improves grip security. A single-position, right-handed clip allows the knife to be carried in the tip-up position, with the tip of the blade upward. A left-handed clip is included.
