The Wedge Guy: Just what can a golf club do?

Published

on

Not to bemoan the subject, but I’ve been in somewhat of a slump lately, and that provided the inspiration for this week’s post.

My slump is a peculiar one, in that I’m driving the ball as well as ever, hitting lots of fairways and getting my fair share of distance. But my iron play – usually a strength of my game – has gone sour. So bad, that one of my regular playing buddies offered his suggestion that maybe it was time to ditch my old Ben Hogan FT. Worth 15 blades for a more forgiving set of irons.

I didn’t choose to get into this explanation with him, but thought it was well worth some time invested in this week’s post. If you are thinking about purchasing any new clubs – whether driver, fairways, hybrids, irons or wedges (I’ll leave putters for a separate conversation) – I believe you should start the process by accurately and honestly defining exactly what it is that you are seeking to “fix” with this new purchase.

I see some golf club advertising in the wedge category, for example, that claims this certain product can lead to “no more chunks or skulls.” The fact is . . . that is impossible. With the possible exception of the putter category, the mere changing of a golf club head design has absolutely ZERO effect on the quality of impact with the ball.

All golf clubhead technology for the past 60-plus years has been focused on two essential goals – to make the ball leave the club faster and/or higher, and to mitigate the loss of impact efficiency as ball contact is made other than on the ideal “sweet spot”.

On that subject, every golf club has a single pin-point spot on the face where energy transfer will be optimized. And no matter whether it is a driver, hybrid, iron or wedge, ball impact elsewhere on the face will result in a reduced smash factor, or transfer of clubhead speed to ball speed. In most club categories, the engineers are always focused on how to minimize that loss of smash factor, so that your “less than perfect” shots can be more acceptable and playable.

But here’s the kicker.

The ball can only react to how that clubface is delivered at impact – clubhead speed, path and face angle, and the point of impact on the face – and the golf club designer can only do so much within those parameters.

For example, a face that is open at impact will cause the ball to fly to the right and probably higher (for a right-hand player), and one that is hooded and/or closing through impact will make it go left and lower. All the technology in the world won’t change that. Likewise, for those shots hit fat or “in the forehead”, it really doesn’t matter what the clubhead design is like.

But a shot hit with a square clubface, approaching the ball on a solid path, but slightly missing the sweet spot, can certainly be helped by improved clubhead technology.
However, my observation of thousands of golf shots of my own and hit by my golf buddies over the many years in this game reveals this simple fact of our crazy game.

The vast majority of bad golf shots cannot be helped by golf club technology, as they are the result of bad swing mechanics, not inferior clubhead design. Those mechanics are mostly influenced by the golfer’s grip on the club and his or her pathway through impact. And for those of us who have hit thousands of golf shots over many years, it quite often boils down to poor mental work leading up to the swing.

This sounds like a crazy “reveal” by someone who has made a living for forty years designing and marketing golf clubs, doesn’t it? Yes, I have spent the better part of four decades working to make golf clubs work better, whether it was the hundred-plus putters I’ve designed, two sets of irons or the dozens of wedges I’ve created. I’m very proud of that body of work, as I’ve always been able to improve each generation of design.

That all said, however, I’m convinced most poor golf shots are pre-ordained before the club is ever taken into the backswing, and no amount of golf club technology will ever change that. The pathway to better and more consistent golf will always begin with improving your fundamentals, starting with your grip and posture at address . . . developing sound swing mechanics . . . supported by a healthy, positive mental approach to each shot . . . and then having the right tools in your bag.

Oh, and back to my own slump? I’m recalling sage advice from my father, given to me so many, many years ago . . .

“There’s nothing wrong with your game, son, that another thousand practice balls won’t fix.”

Terry Koehler is a fourth generation Texan and a graduate of Texas A&M University. Over his 40-year career in the golf industry, he has created over 100 putter designs and dozens of wedges. In 2014, he put together the team that reintroduced the Ben Hogan brand to the golf equipment industry with his TK 15 wedges and Ft. Worth 15 iron designs. Since receiving a U.S. Patent for his “Koehler Sole” in the early 1990s, he has been challenging “conventional wisdom” in the wedge category. In addition to inspiring multiple companies to emulate this sole technology, the performance of his wedge designs have stimulated all other companies to reposition some mass toward the top of the blade in their wedges. Terry is retired from his role as Chairman and Director of Innovation for Edison Golf, and remains active in the industry as an independent designer and consultant.  But his most compelling work is in the wedge category. Since he first patented his “Koehler Sole” in the early 1990s, he has been challenging “conventional wisdom” reflected in ‘tour design’ wedges. The performance of his wedge designs have stimulated other companies to move slightly more mass toward the top of the blade in their wedges, but none approach the dramatic design of his Edison Forged wedges, which have been robotically proven to significantly raise the bar for wedge performance.

    I’m going to disagree. As a person who spent several decades shooting in the 60’s every week (still hold one course record, a 61 at a course near my home), a few years ago I noticed a drop off in my iron play. After some reflection, I put the Mizunos down and went to a more forgiving club. (Taylormade Speedblades about 8-9 years ago). They’re a little bigger, a little lighter, launch a bit higher and yes, a bit stronger lofted. More mass and a bigger face means there’s less torque on shots not hit perfectly. They don’t feel as good as my forged irons (a bit harsh) but I hit more greens and more shots closer to the hole.

    Love this. I am an 8 hcp, have played for most of the last 25 years with a set of 1972 Hogan Apex blades I bought used for $35. Despite playing with other irons (e.g., Callaway x-12 Steelhead, Ping Eye 2, Mizuno modern blades, Ping iE1), my best tournament scores and lowest hcp periods have come with the 1972 Hogan blades.

    I put the Ping iE1s in the bag early this season and thought I’d see my hcp drop 1-2 strokes based on improved results from marginal mishits. But I didn’t break 80 for two months…then put the Hogans back in the bag and broke 80 4x in the next few weeks.

AVL: My U.S. Amateur local qualifying experience

Published

on

This past Monday, I played in the U.S. Amateur local qualifier at Rock Creek Country Club in Portland, Oregon. A full tee sheet from 7:30 a.m. to 1:55 p.m., the top 11 scores would make it to the U.S. Amateur final qualifying.

I teed off at 10:48 a.m.. With the 7:30 am tee time, you can get a feel for the leaders’ pace, and they were off and running on the challenging setup at Rock Creek.

Getting to the highlight of the round on the par five 17th, a drive up the left side and 212 yards left to the front hole location. I took out a 5-iron with plans of middle of the green. The ball ended up 8 feet left of the hole, pin high. A slight downhill putt dropped in for an eagle 3 on the 17th. With the cut line looking to be anywhere from -2 to even par. This was the boost I had been waiting for all day.

With making par from the trees on 18, it was time to wait for a potential playoff with a posted score of one under par 71.

Three hours later, it was playoff time. 8 players for 6 spots. I made par on the playoff hole, which was good enough to advance to the U.S. Amateur final qualifying in July. USGA qualifiers sure deliver on all of the emotions in golf!
