There are probably two reasons for this move back to forged irons and away from cast options. Fifteen years later this percentage was back up to eighty percent. The technology evolution to the cast irons started in the eighties and by the mid-1990s almost half the PGA pros tour were still using forged irons. A high handicap player would probably not be able to notice the difference and would get better results from the cast cavity-backed clubs.

The solid steel construction of the forged iron has a softer feel than the cast clubs and for the low handicap player or professional this degree of feel is significant. These clubs are usually of the blade design and are also known as ‘muscle backed’. This results in a much smaller sweet spot or center of gravity.
This in turn results in greatly improved forgiveness which is a massive help especially for beginners and high handicappers.įorged irons by contrast are solid chunks of steel with the weight more evenly spread but concentrated at the back and middle. The weight is now removed from the middle of the clubhead and distributed around the edges of the face resulting in a much larger sweet spot. The need to eliminate this tendency to spray the ball in various directions, other than that intended, is what led to the development of the cavity-backed clubhead. Missing the sweet spot produces shots that fly off course, either slicing or hooking and can also result in a loss of distance. Another way of expressing the C of G is the ‘Sweet spot’. What every golfer is looking for is accuracy and this is mostly determined by the Center of Gravity (C of G) of the clubhead. Ping continued with this “new” technology and competitors soon followed. Ping is often credited for the early developments in cavity-baked irons although, interestingly, their first club with this feature was a putter. This is a much easier and cheaper method of manufacture. The construction of the cavity backed irons with perimeter weighting, also known as ‘game improvement irons’, consists of molten metals or alloys being cast into a mold. New developments – the cavity-backed iron The sides of the clubhead are then smoothed on a grinder and finally polished and electroplated usually in chromium-nickel before being attached to a shaft. The metal is now placed into a second mold and slowly pressed to its final shape, including the grooves. The excess metal from around the edges is trimmed off by another machine and is then reheated. It is then placed in a primary forging mold where an air hammer press produces the basic shape. Depending on the club being made the steel is heated and then bent to the required angle. The basic technique is to heat steel, usually a bar of 1025 or 1025E steel, to a red-hot temperature. New developments – the cavity-backed iron.
