Abstract
A tool handle including: a body configured to receive a handle of a tool; a hand grip extending approximately perpendicular from the body; and an arm ring rotatably disposed on the body, wherein the arm ring is adapted to be placed in at least two positions, a first position in which the arm ring is generally perpendicular to the hand grip such that a user may place the user's forearm through the arm ring to grasp the hand grip and a second position in which the arm ring is generally parallel to the hand grip so as to minimize the width of the tool handle.

A tool handle comprising:
- a body configured to receive a handle of a tool;
- a hand grip extending approximately perpendicular from the body;
- and
- an arm ring rotatably connected to the body via a ball joint, wherein the arm ring is adapted to be placed in at least two positions, a first position in which the arm ring is generally perpendicular to the hand grip such that a user may place the user's forearm through the arm ring to grasp the hand grip and a second position in which the arm ring is generally parallel to the hand grip so as to minimize the width of the tool handle.
