Among the types of disc golf discs, putters have the thinnest rims and the deepest bodies. These characteristics, in terms of aerodynamics, make them the slowest ones in your arsenal, but they play a crucial role: they're built to handle short, straight shots right into the basket, and their construction prevents them from flying too far off.
Compared to midranges and drivers, a putter has a rounder rim, which comes in handy when aiming at the basket. The design, as well, is built for accuracy: the variables and stability aren't so extreme that, if you miss, you'll be chasing your disc across the green. As such, putters are less likely to skip and have short-range shots mastered.
As a player, especially one out on the green every weekend, you always want to have several putters ready to practice your shot and refine your skills.
