发明名称 Golf club with golf club head having compressible v-shaped grooves
摘要 A golf club with a golf club head having compressible v-shaped grooves is presented. The club head may include a plurality of grooves formed in a striking face. In some arrangements, the grooves have a rectangular cross section. The grooves may also include a compressible insert having a v-shaped end and being formed of a material softer than that of the grooves. As the club head strikes a golf ball, the insert may compress, thereby allowing additional contact between the groove and the ball to impart spin on the ball. In an alternate arrangement, the groove may include a compressible support arranged between the insert and an end of the groove. The compressible insert may be formed of a material softer than the groove and/or the insert and is configured to compress when the club head strikes a golf ball.
