Abstract: The Rocker Handle pertains to the field of hand-held tools and devices. A sleeve-like attachment (the receiver) becomes the new user gripping point, a replacement hand-hold. This arrangement allows the tool's encased handle to move inside the gripped receiver. The receiver attaches to and partially encases a tool's standard or custom handle. The combination of the loose fitting receiver and the encased handle movement within creates a subtle whip-like action of the tool head. The effect is a different feel and action of the modified tool. The user experiences better tool performance, expends less effort while using the tool, and has reduced risk of personal injury.
