  • a typical distance of the approach shot to a cup is often within about 50 yards.
  • a swing length of the approach shot is typically up to a half of a full shot, and it is necessary to slow down a head speed.
  • the player can swing the club at a regular club head speed.
  • the approach wedge and the sand wedge have a heavy club head, when a ball is hit under an appropriate ball-hitting point of a club head including a top, the ball may excessively travel for a longer than expected carry distance.
  • Such a phenomenon of the excessive carry can occur not only with the approach wedge and the sand wedge, but also with a so-called short iron such as the No. 8 iron or below.
  • Patent Reference has disclosed a conventional iron golf club head, which can prevent the excessive carry even in the full shot by filling floating metal powder in a club head main body. With such a golf club head, even when a distance to a cup is for example within 50 yards, it is possible to swing the full shot.

  • the weight of the lower head section of the golf club head is less than that of the upper head section, even in a case of missed shots such as topped shots, in which the lower head section having the light weight hits near an equator of a golf ball, it is possible to reduce a level of an excessive carry. Furthermore, once a player can feel reduction of the excessive carries due to the missed shots, the player may not hesitate to lift a sole of the club head from the ground when the player is in address position, so that the player recognizes to be able to just hit under an equator of the ball with a leading edge of the club head through down blow.
  • the center of gravity of the golf club head becomes high and the distance between a ball-hitting point and the center of gravity becomes longer.
  • the club head can easily rotate downward (in a direction that a clubface stands) upon hitting the ball, and with a gear effect caused by the spin, it is possible to apply strong back spins to the ball.
  • a cushion part on at least one edge section of the toe side and the heel side of the face, there may be also provided a cushion part.
  • the cushion part it is possible to reduce the missed shots caused by hitting the golf ball at the edge section to carry the golf ball in an oblique direction.
  • the present invention it is possible to reduce the level of the excessive carry even in the case of the missed shots such as the topped shot, and to reduce the missed shots such as the topped shots.
