  2. Andrew Demko - AD 20.5 Clip Point - Stonewashed CPM-S45VN & Carbon Fiber - PRIVATE COLLECTION - knife

    KNIFE WITHDRAWN FROM PRIVATE COLLECTION
    * Origin: Withdrawn from a private collection, previously purchased and used
    * Condition: Overall in good condition, a couple of small cosmetic marks of use on the tip of the blade
    * Available on the market: Out of production
    * Sharpness: Factory sharp

    The Demko Knives AD20.5 is a high-quality folder offered at a very competitive price. Fun to use and practical for everyday use, it owes much of its appeal to the innovative Shark Lock: a radical system that guarantees a secure blade lock, keeping your fingers safe at all times.

    The mechanism is activated by pulling back the “fin” with your thumb or index finger, in a movement similar to that of a flipper opener. Once opened, the blade locks securely and the fin becomes a comfortable thumb rest, complete with jimping for superior control. Additional jimping on the back of the blade and an optional high grip further enhance the handling and versatility of this folding knife.

    The AD20.5 represents the perfect balance that every EDC seeks to achieve, and will easily earn a permanent place in your pocket as soon as it enters your collection.
