Abstract
The present invention features a universal primary hand grip device for use with tools and utensils. The primary hand grip has multiple angles by which the hand can grip the shaft of a tool or utensil, thus making the grip ergonomically efficient. When used in combination with a secondary cross-handle, a tool or utensil can become quite easy to use and comfortable to operate. The primary hand grip device of this invention has a grip that slides over, or is made integral with, the end of the shaft of a tool or utensil. The hand grip has a multiply-angled surface, in which the primary hand can assume a substantially straight-angled position (180.degree. angle) with respect to the axis of the wrist. The correct hand position varies with each tool and with each work surface. The proper grip angle for a particular task allows the hand to maintain a straight angle with respect to the wrist axis, while also imparting the driving force of the arm into the shaft of the tool.
