KJH blade is an all wood blade with a burned wood core. Feel of the ball, ability generate topspin, ability to finish points with a powerloop, solid feel at impact, and strong performance on blocks are the important things KJH asked for this blade and it delivers. You get touch in the short game, good soft defense on BH wing, ability to easily vary the spin, and a top end approaching the low/middle OFF range.

NEXY USA staff note :
Nexy Korea President Moon designed this blade for Korean Pro, Kim Jung Hoon. I was present at Nexy HQ when Kim Jung Hoon discussed with President Moon the performance specs he desired. The result after months of protype tests is the Tibhar Kim Jung Hoon blade, whcih became an instant best-seller in Korea.
