![]() Basically the main part of the sole has a low bounce while the leading ¼” of the sole has a very aggressive bounce so the leading edge can’t dig into turf. Eidolon Golf is a small specialty wedge manufacturer that’s come up with a grind they call a V-Sole. Grind can get so creative it can be patented. This illustration from the Eidolon web site is a good one to show not just their proprietary “V-Sole” grind, but the difference between low and high bounce wedges. Some want a little more radius so the club face looks closer to the ball. Some like the sole ground down near the heel so that when they lay the club open the bounce doesn’t increase as much. I won’t pretend to understand all the variations they make available to touring pros, but I do know it can matter greatly to skilled players. Grinding the sole of wedges has become something of an art form that people like Bob Vokey at Titleist have popularized and perfected. When it comes to camber, a lot of pros will grind a little off the leading and trailing edges of iron soles to create a “rounder” shape that cuts down on drag and reduces bounce. But today, most irons have a slight radius that makes them a little friendlier out of rough and tighter lies. Many “players” irons in the past like old Hogans and MacGregors were designed with a very straight leading edge. Camber is the curve of the sole from the leading to trailing edge. Radius is the gradual curve of the leading edge as you look down at the head in the address position. ![]() To alter and fine-tune that dynamic, we come to the “grind.” And here we have to address two more terms: radius and camber. Generally speaking, opening the blade presents more bounce, closing it down less bounce. But things get tricky once you move a wedge from its normal address position. That wonderful “thump” you hear when a pro hits a sand shot is the sound of the bounce on the sole of the club making the first contact with the sand and not the leading edge digging in.īounce is pretty easy to see and understand (and we have a little more here if you’d really like to know more). That’s because the more bounce there is, the more the bottom of the club acts like the bow of a boat to prevent the club from digging into the ground or the sand. Gap and lob wedges generally carry six to eight degrees of bounce while sand wedges usually have somewhere between 12 and 14 degrees of bounce. A set of irons might have one degree of bounce in the 3-iron that gradually increases to seven or eight degrees in the pitching wedge. It’s expressed in degrees and really matters most in higher lofted clubs. The more bounce there is, the higher the leading edge is off the ground when the club is held in its square position. Bounce is the angle of the sole measured against a horizontal line (the ground) when the club is in the address position and the shaft is vertical. When Gene Sarazen soldered a flange to the bottom of his niblick to create the first sand wedge, he was creating what we now call bounce. ![]() Here’s what that means and why you might consider doing the same depending on the courses you play. Many opted to use wedges with less bounce and a grind that produced a sharper leading edge. To deal with the combination of deep, thick rough as well as the extremely tight lies on fairways and in the runoff areas around some greens, players had to resort to wedges that could more easily cut through the thick stuff and not bounce off the tightly mowed turf and blade the ball (as happened to Tiger at the third hole Sunday). So while some are calling Oakmont the true victor this year, I think it might have been modern agronomy that really won. As we saw this weekend, Oakmont Country Club proved itself capable of growing some of the toughest, most gnarly, luscious grass this side of Kentucky.
