1. A locking folding knife comprising:
a handle;
a first pivot axis;
a blade having a cutting edge and a tang, the blade is pivotably coupled to the handle such that the blade is pivotable relative to the handle about the first pivot axis between a retracted position and an extended position, the cutting edge is exposed in the extended position and a portion of the blade is received within the handle in the retracted position;
a locking mechanism comprising a lock in the handle, or in a liner, and the lock being biased to a locked position, wherein the locked position prevents the blade from rotating towards the retracted position;
a switch located in a switch cutout recess in the handle or liner, wherein the switch is operable to move between an engaged position and a disengaged position, wherein when the switch is in the engaged position, the switch blocks movement of the lock from the locked position, and wherein when the switch is in the disengaged position, the lock is free to move from the locked position; and
a spring having two ends, a first curved end arranged within a pocket of the handle, and a second end arranged within an internal sub-pocket of the switch, wherein the second end is curved, and wherein the sub-pocket is surrounded by the switch.
