The IB Putter Sweet Spot Quaternion isn’t your average flatstick. Thanks to its club head design it looks more like something from Star Trek than a golf brand. To find out if the performance lives up to its looks, we put the IB Sweet Spot Quaternion Golf Putter to the test out on the golf course.

NCG SUMMARY

The IB Putter Sweet Spot Quaternion is a bold, futuristic take on a putter. It is driven by the design philosophy of Ivan Ballesteros – nephew of Seve Ballesteros. It promises a pure, zero-torque putting stroke through a symmetry design, balance, and feel. Whilst it may not appeal to everybody visually, it’s a premium putter that rewards a straight-back-and-through stroke.

PROS

  • Outstanding stability and balance
  • Excellent alignment and feedback
  • Premium grip and shaft quality

CONS

  • Visually it won’t be to everyone’s cup of tea

First Impressions

You certainly won’t mistake this for a traditional blade. The Quaternion’s cylindrical, space-age look stands out immediately. It’s symmetrical front-to-back and left-to-right, a design that allows it to be used by both right- and left-handed golfers. While that might sound like a novelty, it stems from a serious engineering aim which is to achieve total balance and zero torque through impact.

It’s undeniably different. I even thought it looked a little weird at first glance, but it is undeniably intriguing.

On-course performance

At address, I found the putter wants to swing straight back and straight through. Golfers who naturally putt on a straight path will feel right at home, it resists twisting and almost guides your hands on plane. For someone coming from a blade-style putter, it was obvious to me to notice instantly the lack of face rotation. A big plus.

The sound and feel at impact on the golf ball are excellent. You are met with a crisp, sort of popping sound that feels both solid and responsive. The graphite shaft dampens harsh vibrations without feeling dead. It offers pleasing feedback on well-struck putts.

Short putts in particular feel automatic. I found that you can see how the zero-torque concept helps keep everything square.

The Sweet Spot Quaternion is the third-generation evolution of IB’s putter line, and, I have to say, it feels like the most refined yet. A graphite shaft helps reduce vibration and enhances feel, while the premium stitched leather grip delivers excellent tactile feedback and a touch of luxury.

The symmetrical central-shaft design means the shaft enters at the putter’s centre of gravity, promoting stability and the same response from either face. I think it is a clever piece of design that also cuts down on manufacturing complexity.

A bold alignment line runs front-to-back across the head, making setup intuitive and helping golfers who rely on a visual line for aiming.

NCG Verdict

Overall, I certainly acknowledge the IB Putter Sweet Spot Quaternion won’t be everyone’s cup of tea aesthetically. But as a piece of engineering, it’s exceptional. It’s beautifully made, easy to align, and promotes an incredibly stable stroke.

If you’re curious about zero-torque design or struggle with face rotation, it’s well worth a test. For traditionalists, the futuristic look may take some getting used to, but it’s one of the most distinctive putters you’ll ever roll.

About the author

Callaway Epic Max driver review
Jack Backhouse

A member of the PGA for 13 years, Jack has lived golf for more than half his life. Inspired by Tiger Wood’s winning putt at the 2008 US Open, an obsession began with watching slow motion golf swings on the internet and reading What’s In The Bag articles in magazines.

Not destined for a life behind the desk in a pro shop, Jack has focussed more on coaching, working closely with regional teams in North Yorkshire and helping golfers of all levels on their journey to enjoying playing the game more. Jack has coached many junior golfers into the county teams, and once worked with a player at the 2018 Open Championship at Carnoustie.

After letting his game fall apart prior to COVID, Jack rediscovered his love for playing golf after joining Silloth Golf Club in 2020 and whipping round the windy, firm links course. Playing regularly with a half set of clubs he has a passion for shot making and developing skill, and claims to have the sharpest 30-100 yard game in the North of England (only because he doesn’t know anyone in the South), and now maintains a +1 handicap at a club much closer to home, Sand Moor GC.

Jack has always tinkered with his equipment, once building his own Frankenstein one length set of clubs after watching Bryson DeChambeau burst onto the scene after winning the US Amateur. He firmly believes in getting custom fit and is happy to debate anyone about blade irons being superior to any other iron category.

Jack loves: playing quickly, 2 ball golf, match play, heathland courses, pencil bags, foursomes, Tiger Wood’s swing 2005-2009.

Jack hates: buggies, unnecessary trees, giving shots, the 7 iron loft debate, graphite shaft lovers weird superiority complex.

Titleist SM10 wedges
