With over 40 years of experience in the golf equipment industry, I have naturally paid close attention to the evolution of golf equipment throughout its modern history. While I’ve never gotten into the collecting side of golf equipment, I have accumulated a few dozen clubs that represent some of the evolution and revolution in various categories. Obviously, as a club designer myself, I ponder developments and changes to the way clubs are designed to try to understand what the goals a designer might have had and how well he achieved those goals.

Regular questions from readers about this innovation or that got me thinking about my own “hot list” of the most impactful innovations in equipment over my lifetime – the past 60 years or so — so let me offer this analysis up to all of you for review, critique, and argument.

Woods

I would have to say that the two innovations in woods that made the most impact on the way the game is played are the introduction of the modern metal wood by TaylorMade back in the 1980s and the advent of the oversized wood, pioneered by Callaway’s Big Bertha in the 1990s. Since then, the category has been more about evolution than revolution, in my opinion.

Irons

Once you get past the innovation in the 1920s to create matched sets of irons, numbered 1 through 10 or “P”, I think there are two major innovations that have improved the playability of irons for recreational golfers. The first is the introduction of offset to help the average golfer keep his or her ball flight from straying right. (But if you naturally draw the ball, this is NOT your feature.) The second would be the introduction of perimeter weighting, which made the lower lofted irons so much easier for less skilled golfers to get airborne. Again, just about everything since then has been tweaking, rather than re-inventing.

Putters

This is probably the most design-intensive and diverse in the entire equipment industry. Thousands of designs and looks in the endless pursuit of that magic wand. The first most impactful innovation has to be the Ping Anser putter, which has been copied by nearly every company that has even thought about being in the putter business. Moving the shaft toward the center of the head, at the same time, green speeds were increasing and technique was moving toward a more arms-and-shoulders method, which changed the face of putting forever. I actually cannot think of another innovation of that scale in the category, but lie angle balancing might prove me wrong, as it is certainly the “real deal.”

Wedges

Very simply, there hasn’t been much revolution in this category. The “wedges” on the racks today are almost identical to those in my collection dating back to a hickory shafted Hillerich and Bradsby LoSkore model from the late 1930s, to a Spalding Dynamiter from the 50s, Wilson DynaPower from the 70s and so on. The closest thing would be the proliferation of specialized grinds and the advances in CNC-milling that allow almost perfect grooves.

Shafts

Hands down, the most powerful innovation is the creation of the carbon fiber (graphite) shaft. After fruitless ventures into aluminum and fiberglass, this direction has improved the performance of golf clubs across the board. You haven’t seen a steel-shafted driver in a decade or more, and irons are rapidly being converted. Personally, I can’t see ever playing a steel shaft again in any club – even my putter! Behind that, I’d have to say the concepts of frequency-matching and “spining” shafts made it possible to achieve near perfection in building golf clubs for any golfer.

Wild Card

This has to go to the invention of the hybrid. After decades of trying to find a way to make clubs with 18-24 degrees of loft play easier, the application of every possible perimeter-weighted iron concept and smaller fairway wood head concept has finally been figured out by Sonartec and Adams. As a result, every golf club brand has now adopted this concept. Golfers of all skill levels are benefiting, as this is just a better way to get optimum performance out of clubs of that loft and length.

So, there’s my review of a lifetime of golf club engineering. What can you all add to this? What do you think I missed? I hope to see lots of conversation on this one.
