Iron sets are the meat and potatoes of a golfer's bag. They are going to cover your distances from 100 yards to 220 yards. There are so many adjectives that describe an iron it can make your head spin. Forged, cast, blades, muscle back, cavity back, hybrid, game improvement, players distance, players. So let me break down a few key differences. Forged versus cast is how the iron was constructed. A very incomplete overview is that a forged iron is hammered into shape and then sanded down, a cast iron club takes liquid metal and pours that into mold. Generally speaking forged irons give the golfer more feel but a cast iron will give more distance. So a more seasoned player might lean towards a forged iron where a newer golfer should probably lean towards a cast iron.
