Demko AD20.5 Shark Foot Grey Grivory, Stonewashed, an undersized, sturdy EDC folding knife for hard work. Designed by Cold Steel's long-time designer, Andrew Demko. Cold Steel's greatest hits have come from his hand. His Shark-Lock™ lock is considered to be the strongest in the world!

Andrew Demko - owner and founder of Demko Knives, first started forging chisels in 1988 when he was in seventh grade. He immediately realised 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 company Cold Steel. At Cold Steel, Andrew has 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.

AUS-10A - Japanese stainless steel, often compared to 440C series steel, and for good reason, as the compositions are similar, but these minor differences make AUS-10 harder (usually hardened to around 60 HRC) and dulls more slowly without losing its rust resistance. Knives made of this steel are relatively inexpensive and will be a great choice if your budget is not too high and you care about stainless.

The Shark-Lock™ mechanism is located on the back of the knife and is operated by a ramp-like 'flipper'. Opening the blade causes the spring-driven locking arm to move upwards and then into a notch in the shank, placing it under the locking pin. Uniquely, the locking mechanism moves forward and backward, simultaneously moving up and down. This increases the size of the blade contact area, providing better mechanical strength in a specific area. And because the drive spring that moves the locking element upwards to the locked position is located in the locking arm itself, it will not be exposed to dirt and debris.

Blade - Shark Foot type, finished with a scratch-masking Stonewashed finish. The blade extends the length of the cutting edge in relation to the length of the slim blade, converging 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 a dual thumb stud or an oval thumb hole. The entire blade is locked with what is considered to be the world's strongest Shark-Lock™.

Handle grips made of Grivory, a practically indestructible material 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. The single-position, right-handed clip allows the knife to be carried in the tip-up position, with the tip of the blade upwards. A left-handed clip is included.
