ABSTRACT:
An ergonomic handle for a spreading tool designed to permit and encourage the user to grasp the handle with his/her fore and middle fingers extended onto the blade. The extended fingers are fully supported by an arch in the head of the handle, which combined with its comfortable gripping portion for the palm, thumb, ring and little fingers, allows proper alignment of the wrist and increased leverage on the blade while working the tool, yet minimizes fatigue, pain and the potential for injury.
