Not all golf irons are created equal. The two types of irons that we will discuss is a forged iron and cast iron. These types of irons were at one point quite different from each other, but as time has gone on, they are becoming more and more similar. Some people think a forged iron is better than a cast without really understanding the differences.
A forged golf iron is a club that is made out of one solid block of metal. The irons are carved and shaped, and they are one solid piece of material. A cast iron is an iron that is made from a mold. Hot metal is poured in the mold into the desired shape, and the result is a cast iron golf club.
The cast golf irons are mostly known as being cavity back irons. Although they are cast golf irons, most people call them cavity back designs.
The only real difference in these irons is that they are made two different ways; however, the process that they go through when they are produced does cause some differences in the performance of the iron itself.
Muscle back (also known as blades) and cavity back irons refer to the way the back of the iron is designed and shaped. The muscle back is thin and solid allowing for more flexibility in play whereas the cavity back iron is thick and hollow, hence the carved out cavity on the back of the iron. There used to be just one iron, the blade, but those solid chunks of metal have evolved into an upgraded muscle back iron and an easier to hit cavity back iron. Back in the day there was a huge difference between the muscle back and cavity back irons, but with the advanced technology today the difference is becoming subtle.
