Knives with double auto lock

Double auto

— the Double auto system is not so much a type of lock as it is a kind of opening mechanism found in front knives (see "Design"). Such a mechanism is controlled by a sliding switch that can move in two directions — to unfold (forward) and to fold (back). The whole system works in this way: when the switch is moved forward or backward, one of the springs is cocked, and when the extreme point is reached, the blade is released and moves in the appropriate direction under the action of the cocked spring. In general, this is a very convenient and practical, and therefore a very popular type of lock among “front locks”.
