    • A folding knife having an elongated handle defining a finger hole proximate one end of the handle and a blade having a cutting edge and pivotally connected to the handle and configured to move with respect to the handle between a retracted position and an extended position. The blade is configured such that a portion of the cutting edge extends into the finger hole upon the blade being in the retracted position. A blade cover is connected to the handle and is configured to move between an operable position and a withdrawn position. A spring is configured to contact and automatically move the blade cover from the operable position towards the withdrawn position, whereby, as the blade reaches the retracted position, the blade cover is automatically moved to the operable position and covers the portion of the cutting edge of the blade extending into the finger hole, and upon the blade moving towards the extended position, the spring automatically moves the blade cover from the operable position towards the withdrawn position.
