BJM Kotahi is a small innovative company that has studied the biomechanics of the putting stroke to investigate “What-Why-When” we do things while putting. This has allowed them to develop and refine a performance putting grip.
BJM Kotahi Putter Grips are not just putter grips, it is a complete putting system and are defined as performance grips that is based on biomechanics and science. Through its unique design and hold system, it allows the palms of the hands to turn up. This results in reduced mobility of the hands, wrists and arms, and influences thoracic rotation which in turn allows the hands to become external drivers.
Putting has never been easy for many of us to master with so many factors coming in to play. The BJM Putting System has just made it a lot easier.
Putting Science Made Simple - Our Science - Our System.
Why do we place our thumbs on top of putter grips?
Well the simple answer is that we have been told that is how it is. This is how they have always been designed but there is no science behind why we do. Having the palms of your hands facing each other allows for full mobility of your hands which is never a good thing when putting.
Having you thumbs on top is great when using your driver/woods/irons as we need the mobility in our hands to be able to load the muscles to execute the shots.
Why do we need this mobility in our hands when it comes to putting, simple answer is we do not! The Kotahi™ has a unique design and hold system allowing us to correctly rotate using our thoracic. This in turn removes the hands, wrists and arms out of play. This results in the head of the putter staying perpendicular to the swing arch and has a positive impact on consistent putting.
By turning both palms up we reduce the mobility in the joints of the hands and arms thus resulting in:
• Reduced unwanted movement in the putter head.
• More consistent putter arc and stroke length.
• Reduced face rotation & variations between backstroke and impact.
• Help overcoming physiological glitches also known as "The YIPS".
Within the BJM Kotahi™ range there are 2 putter grip sizes, Standard and Undersize, both of which are a Giant profile. There are 2 different skins/feels, these are Silicone and Polyurethane (PU). The Kotahi™ range provides a putter grip option for all golfers.
We recommend that the BJM Hold System is adopted to fully benefit from its unique design. However, all grip styles can be accommodated using Kotahi putter grips, traditional, left hand low, saw and claw.

The hold is very easy to use and self explanatory. You will be putting correctly in 5 minutes.
The bore of the BJM Kotahi Putter Grip is parallel, through the entire length of the grip. As putter shafts generally taper, the area where the lower part of the grip will locate may need building up/packing out with build up tape to accommodate the 0.600 core diameter.
