These are a few things that make a great golf club iron set, including: - A good selection of clubs: you should have at least 3-9 irons, as well as a pitching wedge and sand wedge - Forged clubs: these are made from a single piece of metal and are designed for better control - Cavity back clubs: these have a hollowed out back which makes them more forgiving - A quality construction: this ensures that the club will last for a long time When you're looking for a new set of irons, it's important to keep these things in mind. You'll also want to make sure that you buy clubs that are the right length and weight for you.
