Putters generally come in three styles of clubhead, and three lengths. Clubheads can be a traditional blade, a heel-toe clubhead or a mallet clubhead. Lengths are standard, belly putters, and broomstick putters.

 

Putters are designed to used on the putting green. The key to using a putter from off the putting surface is a low, smooth cut of turf.
