Description

    TECHNICAL FIELD
  • [0001]
    This disclosure relates generally to golf club heads, and relates more particularly to golf club heads and methods of manufacturing a golf club head.
  • BACKGROUND
  • [0002]
    Golf clubs and specifically golf club heads of various designs have typically been developed to improve the functionality of a golfer's swing and resulting golf shot. In particular, many golfers are unable or lack consistency to hit “down” on a ball, that is, to regularly hit the ball squarely. Golf club design and particularly, golf club bead design may be used to optimize a golf club head's weighting scheme, for example, center of gravity position and moments of inertia. Such designs can mitigate a golfer's inconsistency problems. Perimeter weighting and additional lower toe weighting may strategically position the center of gravity and may induce the golfer during his swing, to hit “down” on the ball, thus, hitting the ball squarely.
