Abstract
An ergonomic hand grip for a hand operated tool has a pair of spaced apart curvilinear side beams having first ends and second ends, the first ends being coupled to each other; a forearm brace coupling the second ends of the side beams to each other, the forearm brace extending in a direction from the second ends toward the first ends, and only on one side of the side beams; and a gripping member mounted between the side beams, the gripping member being neither parallel to nor perpendicular to said side beams. The gripping member acts as a flat spring and the side beams act as a pair of torsion springs.
