A folding tool includes a handle and an implement pivotally coupled to the handle according to one embodiment. The implement is adapted to travel between a closed position and an open position and has a tang with a contoured surface. A spring arm has a first end coupled to the handle and a second end adapted to interact with the implement. The spring arm 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 and also locks the implement into the open position.
