发明名称 Golf club head with visual swing-directing cues
摘要 A golf club head adapted to provide a visual cue to a golfer which promotes an inside-outside forward swing of the club head. The club head includes three parallel, visual cue lines, which are provided by the outer edge of the club head toe and the two edges of the face lines. All three cue lines are slanted toward the golfer to provide a visual cue which promotes an outside-inside backswing, which results in a desired inside-outside front swing.
