- The present invention relates generally to golf clubs and, more particularly, to a set of golf clubs having similar lofts.
- Iron type golf clubs generally include a front face, a top line and a sole. The front face interfaces with and strikes the golf ball. A plurality of score lines or grooves are positioned on the face to assist in imparting spin. The top line is generally configured to have a particular look to the golfer and to provide weight. The sole of the golf club is particularly important to the golf shot because it contacts and interacts with the ground during the golf shot.
- Wood type golf clubs are hollow clubs that generally include a front face, a crown and a sole. Again, the front face interfaces with and strikes the golf ball and includes a plurality of score lines or grooves. The crown is generally configured to have a particular look to the golfer. The sole contacts and interacts with the ground during the golf shot.
- Prior golf clubs have included a variety of configurations to provide various benefits. However, golf club sets have a plurality clubs of different lofts to allow a player to hit the ball different distances. For example, sets of irons generally include 3 iron, which has a loft of about 22 degrees, through pitching wedge, which has a loft of about 48 degrees, with each club in between having about 3-4 degrees of loft difference from the next club in the set. Woods similarly come in a variety of lofts. For example, drivers are available in lofts from about 5 degrees through about 13 degrees. A 3-wood, generally the next wood in a set of woods, has a loft of about 13-15 degrees, and 4- and 5-woods generally have lofts of about 18 and 21 degrees, respectively.
