Jack Nicklaus dominated golf with a set of clubs that, by today's standards, look more like museum relics than high-performance equipment. Yet, with these very tools, he amassed 18 major championships. This article will walk you through the iconic clubs the Golden Bear used throughout his career, from his persimmon woods to his legendary putter, and explain what your own game can learn from his classic equipment choices.
You can’t talk about the clubs Jack Nicklaus used without talking about MacGregor Golf. For the vast majority of his professional career, from his rookie year in 1962 until the late 1990s, the Golden Bear was synonymous with the brand. It was a relationship built on loyalty, performance, and a mutual commitment to craftsmanship.
Unlike today, where players change sponsors and equipment annually, Nicklaus was a picture of consistency. He trusted what worked, and what worked for him was forged steel and hand-shaped persimmon from MacGregor. This partnership defined his equipment lineup and shaped his approach to the game, demanding precision and rewarding it with unparalleled feel and control.
When you picture Jack Nicklaus on the tee, you likely see him launching one of his famous high, fading drives. For most of his major victories, he did this with a persimmon wood driver. These clubs were works of art, crafted from wood, with small heads (around 190cc, less than half the size of a modern 460cc driver) and a sweet spot roughly the size of a dime.
His primary weapon was a MacGregor Tourney M85W Eye-O-Matic driver. Here’s what made it so different:
What You Can Learn: Playing a persimmon driver was a lesson in accountability. It forced golfers like Nicklaus to focus relentlessly on finding the center of the clubface. While today's drivers are incredibly forgiving, you can adopt Jack’s mindset. Don't rely solely on technology to fix mishits. Spend time on the range using impact tape or foot spray to identify where you're striking the ball. FInding the center will always produce the best results, no matter what club you’re using.
If the persimmon driver was the powerhouse, the irons were the surgical tools. Jack used forged blades his entire career, clubs known for their thin top lines, minimal offset, and complete lack of perimeter weighting. He valued feel and workability above all else.
In his early years, Nicklaus played a set of MacGregor Tommy Armour 915T irons. These were classic, muscle-back blades. Hitting these well meant finding the tiny sweet spot concentrated directly behind the middle of the face. An accomplished ball-striker could manipulate the ball's flight with ease - hitting high draws, low fades, and anything in between. But for the average player, they were incredibly intimidating.
Later in his career, he helped design and played the Nicklaus Muirfield and Muirfield 20th irons. These clubs, bearing his own name, were the culmination of his philosophy on iron play. They were more than just equipment, they represented a standard of excellence.
What You Can Learn: Playing blades teaches you to be a better ball-striker - you get instant, unmistakable feedback. If you hit it thin, your hands sting. If you catch it perfectly, it feels like nothing at all. While you don't need to rush out and buy a set of butter knives, understanding this concept is valuable. If you want to improve your ball-striking, ask a friend or your local pro if you can hit a few shots with a blade. The feedback you receive might highlight flaws in your swing that a game-improvement iron would hide.
No discussion of what golf clubs Jack Nicklaus used is complete without mentioning his 1-iron. Forged by MacGregor, this club was his faithful weapon for tight fairways and long, piercing shots into windy par 5s. Most famously, he hit a soaring 1-iron on the 17th hole at Pebble Beach during the final round of the 1972 U.S. Open. The ball landed softly and struck the flagstick, leaving him with a tap-in birdie to seal the championship.
The 1-iron is essentially extinct now, replaced by much more forgiving hybrids and utility irons. Hitting a blade-style 1-iron required tremendous swing speed and the precision of a surgeon. There was no room for error. Jack’s ability to pure this club under the ultimate pressure cemented its legendary status.
What You Can Learn: Every golfer needs a "go-to" club they trust completely under pressure. For Jack, it was the 1-iron. For you, it might be a 7-wood, a hybrid, or your favorite mid-iron. Whatever it is, identify the club that you can step up and hit with absolute confidence when the heat is on. Practice with it until it feels like an extension of your body, just as Jack did with his old butter knife.
Perhaps Jack Nicklaus’s most famous club was his putter, a relatively simple blade design called the Acushnet George Low Wizard 600. He used this same putter for the vast majority of his major championship victories, and the story behind it says a lot about his practical, performance-driven mindset.
He didn’t have a flashy putter sponsorship. Instead, he found this putter in the early 1960s, liked the look and feel of it, and stuck with it. He famously customized it himself:
His putting stroke was just as unique, characterized by an upright posture and a "popping" action where he used his hands and wrists more than modern technique would advise. But it clearly worked. That ‘ole George Low putter sank more meaningful putts than any other club in golf history. The Golden Bear trusted his personal feel above anything a manufacturer could tell him.
What You Can Learn: The lesson from Jack's putter is profound: confidence is king. Your putter doesn't need to be the newest model or the most expensive. It needs to be the one that feels right *to you*. Don't be afraid to experiment. Add lead tape, change the grip, or try a different alignment aid. The goal is to find a club that you feel absolutely certain with when you’re standing over a critical 5-foot putt.
The equipment Jack Nicklaus used - the persimmon woods, forged blades, and simple putter - demanded a level of perfection that is almost unimaginable in today's game. These clubs rewarded pure strikes and ruthlessly punished mistakes, underscoring the incredible talent and dedication that made him the greatest champion in the sport's history.
