What is grind on a wedge?

Grind on a wedge refers to the shaping of the sole (bottom) of a wedge club which is designed to help the player use the club effectively from various types of lies. The grind can affect the angle and shape of the sole, as well as the amount of bounce (degree of curvature on the sole) on the club. Different types of grinds are often used to suit different playing styles and course conditions. For example, a player may choose a high-bounce grind for soft, fluffy sand or a low-bounce grind for firm, tight lies. Ultimately, the grind on a wedge can greatly impact a player's ability to control their shots, especially around the greens.
