A putter is the club that you use one the green. Like irons there are two types of putters: mallet putters and blade putters. Blades are thinner putters where mallet putters have a bigger body. Putters come in about 33-35 inches long. The one thing that putters have in common is that all putters have some type of alignment that runs up the middle.
