BJM Kotahi Grips
BJM are a small innovative company that uses golf swing bio-mechanics to investigate what – why – when BJM do things in a golf swing and do their best to deliver a filtered simplified message to their followers and athletes.
BJM believe that putter grips are designed poorly.
If you look at the way we should hold a putter then it sort of makes sense to make the putter grips larger, fatter and with a shape that allows the palms of the hands to turn comfortably up or palms under the bottom of the grip. How we connect the hands becomes obsolete simply because we have reduced the mobility of the joints in the hands and arms by turning the palms up.
To understand this more then we would have to go back to the beginning, which believe it or not is the end. What I mean by that is we must investigate the way the ball rolls and what is an effective and efficient roll. Why do we worry about ball roll? Well once we can create a consistent even roll on the ball we are then able to predict the balls behavior as it roll along the putting surface, this way reading greens becomes a repeatable learnable skill.
Look at what mechanical movements creates inefficient positions for the putter head/face etc and by matter of deduction work out a mechanical system to reduce the inconsistency in the motion.
