    Abstract: An ergonomic, multi-purpose, attachable and adjustable, auxiliary handle assembly that provides a single supplementary handle for multiple tools and implements. The handle assembly is comprised of an ā€œLā€-shaped cylindrical bar that is combined with an adjustable yet lockable, hinged clamp that can be conveniently positioned along the primary cylindrical shaft of elongated tools and implements. This adjustable placement of this new auxiliary handle provides greater convenience in utilizing the tool to maximize its leverage or lifting capability while reducing the risk of muscular strain and fatigue. The adjustable feature allows operators of different sizes; tall to short, to conveniently place the adjustable handle on their tool or implement, at a position on the elongated shaft, that maximizes their preferred handling of the tool for operation. This auxiliary handle allows the user to maximize the effective use of the tool while reducing arm and back strain or injury.
