Abstract: A new Golf Club Head design, as compared to the previous art, Cylindrical in shape, with a larger more concentrated Circular face that has Circular Grooves, with a Convex back, with no Heel and Toe, has a sole plate that wraps around the convex back up to the half mark on both sides of the wooden golf club head, and a unique Neck, Hosel Tube Neck and Shaft ‘placement’ that abuts the approximate Center on the outside at right angles to the golf club head. And this new design incorporates a multifaceted hand grip for the club shaft. This Cylindrical shape head will permit the club head to be always soled and as such, the golf club will not fall backwards as the prior art does without the shaft being held firmly by the golfer. And, so, with this new multifaceted hand grip design, the golfer would not have to hold onto the club shaft any tighter in order to prevent the golf club from twisting, in his/her hands, at impact with the golf ball.
