Demko Knives is the life’s blood of brothers, John and Andrew. They offer custom knives with innovative and rugged designs meant to be used. Not content with what has already been done, Demko has created two new locking systems (Triad and Scorpion) that are more durable than contemporary offerings yet simple to use. On the AD-10 and many of the Cold Steel collaborations the Triad lock is featured heavily. This lock offers the same easy interface as a traditional back-lock but with much greater strength. The Scorpion lock is a new take on the folding knife lock, being both incredibly strong and easy to use. One hand operation is easily attainable as is a rock solid lock up. The AD-15 has an S35vn blade and G-10, Micarta, or Titanium handle scales. The blade stock is a beefy .180 inch thick, but comes down to a nice slicey edge, giving you a strong and capable, yet useful blade. Thanks to the clever design the AD-15 comes in at only 6.4 oz despite the 3.78 inch blade. The blades are machine ground then finished by hand to keep the knives as affordable as possible and keep up with demand. Demko uses high quality materials and makes all their knives in America to very strict quality standards.
