What Does PING Stand for in Golf?

By Spencer Lanoue

PING isn't actually an acronym, but the signature sound heard by an engineer named Karsten Solheim in his garage back in 1959. That pleasant, metallic *ping* from his prototype putter not only gave the company its name but also signaled the start of a revolution in golf equipment design. This article will tell the story behind that sound and explore the groundbreaking innovations that made PING one of the most trusted names in golf.

The Sound That Started It All

The story of PING begins not in a high-tech lab, but in the humble garage of a General Electric engineer named Karsten Solheim. A passionate golfer, Karsten was constantly frustrated by his putting. He knew there had to be a better way. Relying on his engineering background, he began tinkering, convinced that scientific principles could solve his on-green woes.

In 1959, he created a prototype putter he aptly named the "1A." Unlike the traditional blade putters of the day, which were heavy and unforgiving, Karsten’s design looked radically different. It featured an odd-looking cavity behind the face and a distinct weight distribution. When he struck a putt, the putter head vibrated at a specific frequency, creating a unique, high-pitched ringing noise. He remarked to his family, "I've got a PING!"

That sound was more than just a name, it was audible feedback. A well-struck putt produced a crisp, clear “ping.” A mishit sounded dull and muted. For the first time, a club was audibly telling the golfer how well they struck the ball. Karsten patented the design and began building putters by hand in his garage, selling them out of the trunk of his car to fellow golfers. The business was born, and the sound of golf was about to change forever.

From Garage Tinkering to an Engineering Powerhouse

Karsten Solheim wasn’t just a tinkerer, he was a brilliant problem-solver who approached club design with an engineer’s rigor. He saw flaws in the clubs everyone else was using and dedicated himself to fixing them. His core philosophy was simple but revolutionary: use science to make golf easier for the average player.

This commitment to performance and engineering drove the company's early growth. While other manufacturers focused on style and tradition, Karsten focused on physics. He observed that on mishits, the putter head would twist, sending the ball offline. How could he stabilize it? This question led to his first and most important innovation.

Sales grew steadily, boosted by a PGA Tour victory in 1962 using a PING putter. By 1966, the demand was so high that Karsten, nearing retirement from GE, faced a choice. His wife, Louise, encouraged him to take the leap. He resigned from his stable engineering job and focused on PING full-time, founding Karsten Manufacturing Corporation and moving the business from his garage to a dedicated factory in Phoenix, Arizona. This physical move mirrored a shift in the entire golf industry, which was about to feel the full force of Karsten’s innovative thinking.

PING’s Game-Changing Innovations

PING’s legacy is built on a foundation of industry-firsts that have since become standard in golf club design. These weren’t gimmicks, they were engineering solutions that genuinely helped golfers play better.

Heel-Toe Weighting (Perimeter Weighting)

Before PING, almost all irons and putters were "blades." All the mass was concentrated directly behind the center of the face. If you hit the ball perfectly in the middle, it was fantastic. But miss by even a fraction of an inch toward the heel or toe, and the club head would twist significantly, causing a dramatic loss of distance and accuracy.

Karsten’s brilliant idea was heel-toe weighting. By taking weight out of the center of the clubhead and pushing it to the edges (the heel and the toe), he drastically increased the club’s moment of inertia (MOI). Think of it like a figure skater spinning: when their arms are pulled in, they spin fast. When they extend their arms, they stabilize and slow down. By pushing weight to the perimeter, Karsten made the clubhead more stable and resistant to twisting on off-center hits. This created a much larger effective hitting area - the "sweet spot" - making golf significantly more forgiving for everyone.

The Legendary PING Anser Putter

If you've played golf, you have seen a PING Anser putter - or a copy of it. Created in 1966, the Anser is arguably the most influential club design in history, with over 500 wins on the PGA tour alone.

The design, famously sketched by Karsten on a 78-rpm record sleeve, was genius in its simplicity. Frustrated because the name wouldn't fit on the small putter head, his wife Louise suggested he just drop the 'w' from the word "Answer." The name “Anser” was born.

The Anser perfected heel-toe weighting in a putter and introduced a revolutionary hosel design (the part that connects the shaft to the head). This "plumber's neck" hosel correctly positioned the shaft and gave players a clear, unobstructed view of the blade at address. The combination of balance, feel, and performance was so perfect that nearly every major equipment manufacturer today produces a putter based on the original Anser blueprint.

Investment Casting for Precision

To produce his radical new club designs - like irons with a hollowed-out cavity back - Karsten needed a new manufacturing method. Traditionally, irons were forged, which meant heating and hammering a single piece of steel into shape. This method worked well for classic blades but made it difficult to create complex shapes and precisely distribute weight.

Karsten turned to investment-casting, a process more common in the aerospace and dental industries. It involves pouring molten metal into a ceramic mold that was created from a wax replica of the clubhead. This allowed for intricate, finely detailed designs with a precision that was previously impossible. Most importantly, it made creating cavity-back, perimeter-weighted irons both consistent and affordable, bringing "game-improvement" technology to the masses.

The Color-Code Custom Fitting System

Karsten knew that golfers came in all shapes and sizes. He understood that a club built for a touring pro who is 6'3" wouldn't work for an amateur golfer who is 5'7". He believed that for a golfer to be consistent, their clubs needed to match their body and their swing.

This led to one of PING’s most enduring contributions: the color-code system for custom fitting. PING started painting dots of color on the hosels of their irons to denote the club's "lie angle" - the angle between the shaft and the sole of the club.

  • A player who was taller or had a more upright swing would need a more upright lie angle (like a blue or green dot) to prevent shots from going left.
  • A shorter player or someone with a flatter swing would need a flatter lie angle (like a red or orange dot) to prevent shots from going right.

This system transformed club buying. It was the first time an average golfer could walk into a pro shop and get fit for a set of clubs specifically tailored to their swing, a service once reserved exclusively for top professionals.

The Iconic PING Eye2 Irons

Released in 1982, the PING Eye2 iron is one of the best-selling irons of all time and a perfect example of all PING’s philosophies coming together. The distinctive head shape featured extreme perimeter weighting, with a massive cavity back and a wider sole that helped the club glide through turf. They were incredibly easy to hit.

The Eye2s were so innovative that they also created one of the biggest controversies in golf history over their "U-grooves." PING engineered the grooves on the clubface to be closer together than any before them, which imparted more spin - especially from the rough. The USGA and PGA Tour eventually banned the original design, leading to a decade-long legal battle. The controversy only solidified PING's reputation as a company that relentlessly pushed the boundaries of performance to help golfers.

The Legacy: Built on Engineering and a Promise

Karsten Solheim built his company on a promise: to design and produce golf clubs that made the game more enjoyable for the average golfer. He wasn’t interested in trends, he was interested in results. His unwavering commitment to quality, performance-driven engineering, and custom fitting is a legacy that continues today. PING remains a family-owned company, still operating out of Phoenix, and its modern clubs, from the G-series drivers to the latest putters, are direct descendants of the ideas Karsten first had in his garage more than 60 years ago.
