Sand wedge and club head thereof

Abstract

A sand wedge and its club head are provided for reducing a striking resistance, and the sand wedge includes a club head coupled to a rod and a weight protrusion of the club head. The club head includes a club head body, an inlay formed on the club head body, and a hollow portion penetrated through the inlay. The weight protrusion is extended to the rear from the bottom of the inlay of the club head body, and provided for adjusting the weight and the center of gravity of the club head, such that when a golfer strikes a golf ball in a sand pit, sands can pass through the inlay to reduce the striking resistance.
