Abstract
A leaf spring assisted opener for a folding tool such as a folding knife. The folding tool includes tool pivotally carried by a handle. The tool defines tang at the proximal end, and on which is carried a cam. A first liner defines a leaf spring for assisting in the opening of the tool. The leaf spring defines an elongated, arcuate configuration having a distal end adapted to engage the cam of the tool. The tang of the tool defines a shoulder strategically configured and positioned such that when the tool is in the closed position, the leaf spring engages a first side of the shoulder to bias the tool in the closed position. As the tool is pivoted from the closed position, the leaf spring eventually engages a second side of the shoulder and encourages the tool to its open orientation.
