<p>A golf putter with a dual-friction curved face including a shaft having a grip provided at its upper end, and a putter head connected to the lower end of the shaft and having a putter face convexly curved so as to substantially correct directional error in putting, the golf putter wherein the putter face has a radius of curvature of approximately 400 mm to approximately 900 mm so as to maximize a direction error correcting effect, the shaft which is the rotation center of the putter head is positioned approximately 5 mm to approximately 20 mm in rear of the foremost part of the putter face so as to substantially correct the directional error, and the putter face has a dual-friction structure in which friction resistance differs in a heel-to-toe direction and in a vertical direction to decrease directional error due to inaccurate putting strokes and to increase top spin to a golf ball. In the golf putter with a dual-friction curved face, directional error can be corrected so as to putt in an intended target direction, by employing a low friction material as a putter face material and making the putter face convexly curved, even when a putting stroke direction does not coincide with the target direction or the putter face of a putter head is not perpendicular to the target direction due to a golfer's inaccurate putting posture, habits, or strain.</p> |
