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°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.

A hand grip device disposed at an end portion of a tool or utensil for gripping the tool or utensil by a hand that imparts driving motion to said tool or utensil, comprising a shaft portion disposed over an end portion of said tool or utensil, and an ergonomic, solid grip portion adjacent said shaft portion, said solid grip portion having a surface containing multiple-angle grip sections for gripping the tool or utensil at different angles of attack with respect to a work surface, whereby the hand can assume a substantially straight-angled position (180°angle) with respect to an axis of the wrist of said hand, while imparting a driving force to the tool or utensil, and additionally whereby a fatigue condition in said wrist, such as carpal tunnel syndrome, can be avoided because the wrist can avoid assuming a substantially bent position when the hand grips said solid grip portion at an angle of 180°with respect to said axis of said wrist, said surface of said solid grip portion forming a substantially semi-circular, closed loop with said shaft portion, and including in sequence a 45-degree, angled portion with respect to said shaft portion, followed by a substantially straight portion that is Substantially parallel to said shaft portion followed still by a 135-degree, angled portion with respect to said shaft portion for completing said substantially semi-circular, closed loop.
