1. Blade Putter: The blade putter is the most common type of putter and has a traditional design with a small clubhead and a straight, flat blade. It is popular among golfers who prefer a simple, classic look and feel. Blade putters typically have a lower moment of inertia (MOI) than other putter types, which means they are less forgiving on mishits. 2. Mallet Putter: The mallet putter has a larger, more rounded clubhead than the blade putter, and it typically has a higher MOI, which makes it more forgiving on mishits. Mallet putters are available in various shapes and sizes, and they often have additional weight in the heel and toe to help with stability and balance. Some mallet putters also have alignment aids on the clubhead to help golfers aim more accurately. 3. Center Shafted Putter: A center shafted putter is designed with the shaft in the center of the clubhead, rather than at the heel. This design can help golfers maintain a more consistent stroke and a straighter putting line. Center shafted putters are available in both blade and mallet designs. 4. Face Balanced Putter: A face balanced putter is designed to have the clubhead's face pointing upwards when the putter is balanced on a finger placed directly under the shaft. This design promotes a straight back and forth putting stroke and is often preferred by golfers who tend to have a straight or slight arc in their putting stroke. 5. Toe-Weighted Putter: A toe-weighted putter has additional weight in the toe of the clubhead, which helps to promote an open and closed face angle during the putting stroke. This design is often preferred by golfers who tend to have an arced putting stroke. 6. Long Putter/Belly Putter: A long putter, also known as a belly putter, is designed with an extended shaft that rests against the golfer's belly or chest during the putting stroke. This design can help golfers maintain a more stable putting stroke and reduce the amount of wrist movement involved. However, the use of long putters has been restricted by golf's governing bodies, and they are no longer allowed in professional play.
