Abstract
A folding tool includes a handle and an implement pivotally coupled to the handle. The implement is adapted to travel between a closed position and an open position. The implement includes a tang having a contoured surface. The folding tool also includes a locking device movable between a locked position and an unlocked position along an axis that is transverse to a plane defined by the implement. The folding tool further includes a cantilever spring having a first end coupled to the handle and a second end adapted to interact with the tang of the implement. The spring exerts a closing force on the implement when the blade is in a closed position. The spring exerts an opening force on the implement during at least a portion of the travel of the implement between the closed position and the open position.
