£107.64This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.
Demko AD20.5 Shark Foot Grey Grivory, Stonewashed rugged and durable 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 – a high-carbon stainless steel produced by Takefu Special Steel Corporation, based in Fukui, Japan. This steel is rich in vanadium 0.27% (V), molybdenum 0.31% (Mo), and chromium 14.5% (Cr), enhancing its overall performance. The balanced combination of high carbon 1.05% (C) and chromium 14.50% (Cr) makes AUS-10A a stainless steel with excellent corrosion resistance, high hardness (58-61 HRC), and long-lasting edge retention. As a result, AUS-10A sharpens easily, allowing for a razor-sharp edge. Commonly used in premium knives, it offers an ideal balance of hardness, corrosion resistance, and ease of sharpening.
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.
