Korean Hidden Technology AutoFlex Driver shafts came to the US market several years ago. I saw one in 2021. They cause a sensation with a $790 price point. They were very light weight and started a trend for light weight driver shafts. Ultimately the recreational US golfer was not ready for light weight shafts at that price point.
I met with Korean Hidden Technology at the PGA 2025 merchandise show and shot an interview in their booth. It is on the list of videos that need to be published. They followed up with a shipment of review samples of every SKU they make. This is the first of many reviews of the 100+ shafts that arrived. They have created heavier, stiffer shafts for the US market. And, in many models they offer matched driver, fairway and hybrid shafts.
