Abstract
A golf tee has a stake made of a rigid material such as a rigid polymer, combined with a flexible crown with flexible projections and possibly also a flexible pivot point. This reduces resistance at impact, producing less friction and low ball spin. As a result, distance and accuracy are improved. The fusion of the rigid and flexible materials provides a tee that can tolerate repeated hits and be used over and over.
