Abstract
A spiral stake includes a handle structure which facilitates transfer of downwardly and torsionally directed forces from a user's hand to the stake during installation in the ground at a selected location. The spiral stake includes a spiral section, and a straight transition section extending between the handle and the spiral section. A portion of the handle contacting the users palm when downward and torsional force is applied thereto presents a convex curvature of suitable dimension and shape characteristics to distribute resistive forces comfortably to the user's hand. In a preferred embodiment, an opposed region of the handle contains a series of indentations forming a grip for the corresponding reception of the user's fingers, resulting in improved ergonomic feel and force-transfer efficiency. The opposed region is advantageously of sufficiently large dimension to accommodate all four fingers of an adult hand opposed to the thumb, to provide maximum comfort and to afford greater mechanical advantage during installation.
