Korea Hidden Technology · by DUMINA
The proprietary design inside every DUMINA shaft, and the innovation behind autoFlex and AUTOPOWER.
Designed by DUMINA · Made in Korea
We make one of the most copied shafts in the world, so protecting it became part of the job. Materials, layup, process: how it's made is not public. The name says it: Korea Hidden Technology.
The results, however, are fully public. Every launch monitor prints them.
What we can tell you
20–30g lighter than a conventional shaft, and that much strain off your body.
Whatever your swing speed, the shaft optimises how your power reaches the ball.
It settles the swing into a stable shape, and accuracy follows from that.
Power transfer and flexibility working together: farther, and more precisely.
Flex line
Ultra-light, for the smoothest swing in golf. Light and soft, yet it adapts to swings far faster than its numbers suggest. KHT runs through the entire shaft.
Power line · since 2013
Where DUMINA began. The substantial feel pros trust: rock-steady through the swing, solid and powerful at impact.
The final check is done by hand, not machine. Every shaft is individually inspected before it ships.
Korea Hidden Technology cannot be made outside the DUMINA factory. A copy can match the look, never the inside. Every genuine shaft carries a 12-character engraved code, so check it before you buy used or from abroad.
Verify your shaftKHT is at the heart of every autoFlex shaft, designed to be easy to swing and to add kick at impact. Fitting the shaft to your swing gets the best results.
