Abstract
A folding knife includes a handle having a pivot axis, a blade attached to the handle, a movable member that moves about the pivot axis, an urging spring, and a switching mechanism. The movable member has an engaging claw. When the blade is in a folded position, the switching mechanism holds the movable member in a disengaged state, in which the engaging claw is disengaged from an engaging portion of the blade. When the blade moves from the folded position to the switching position, the switching mechanism switches the movable member from the disengaged state to an engaged state, in which the engaging claw is engaged with the engaging portion, thereby moving the movable member in the open direction by the urging spring to move the blade from the switching position toward the open position by the movable member.
