You could classify BJM putter grips alongside models from the usual suspects – like Golf Pride, Lamkin and Supersoft – but actually they are something different.

Rather, this is a new putting system, and one where the grip design and the way you hold the club work together.

In simple, non-technical terms, BJM’s Kotahi grips are triangular. More precisely, the grips are teardrop-shaped, so that your hands wrap comfortably around a rounded back.

What that allows you to do is place your palms underneath the grip with thumbs on either side. This promotes a more consistent putting stroke and reduces unhelpful mobility.

BJM putter grips: Why they work

“The correct grip promotes better biomechanics when putting,” explains BJM’s Nick Campbell.

“With other grips, the thumbs are placed on the flat section at the top of the grip resulting in a full range of mobility in the hands.

“The unique design of the Kotahi grip allows the palms to sit under the grips so that the palms are facing up and the thumbs are placed on the side of the grips.

“By having the palms facing up, we dramatically reduce the mobility and this encourages thoracic rotation – which is perfect for a consistent putting stroke,” said Campbell.

The name ‘Kotahi’ derives from the Maori word meaning ”to be one and unite together”. What’s that got to do with BJM putter grips? Well, they share the core principles of unity and strength.


BJM putter grips: Biomechanics

BJM say the concept for the grips is based on biomechanics. Approved by the R&A and designed by Australian PGA professional Vaughan Mason, who has 15 years’ experience working in biomechanics, the grips are now available here. They are currently in use on tour – with one in the hands of a multiple major champion.

The principle benefits of BJM putter grips include: reducing mobility in your arms, wrists and hands; a more consistent stroke arc and length; reduced face rotation throughout the stroke; promoting thoracic rotation; making your hands external drivers; externally extending your shoulder joints; creating synergy in the putter head; and promoting an antagonistic grip.

In practice, it means improving your putting consistency – in terms of stroke and, even more importantly, strike.

You only have to put your hands on the grip to feel the difference. Where conventional grips have that flat front we are all so used to, the Kotahi puts the palms underneath the grip. It feels instinctively right and comfortable – factors so important to success on the greens.

Intrigued? You should be.
