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 most US golfers were 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. They followed up with a shipment of review samples of every SKU they make. This is the first Korean Hidden Technology shaft that was available in the US in 2021. I had access to a single shaft then unlike now that I have measured all the shafts available at https://autoflex.us/. It was no small task measuring the 100+ shafts they supplied. KHT makes driver, fairway and hybrid shafts in each model family. Some models also have matched iron shafts. This is unique. The autoFlex is available in 4 color choices. That added some confusion to sorting the review samples. You must ignore colors and focus on the model designation printed on the shafts.

The Modus3 Tour 115 shaft is now available with the standard Modus3 chrome finish and is in the 2022 Mizuno fitting cart. We now have Nippon Modus3 shafts in 5 weights, 105, 115, 120, 125 and 130. It is important to note that these are more than simple weight options of the same design. The Modus3 120 and the Modus3 130 are radically different designs.

The Mitsubishi Diamana PD is the fifth generation of the Diamana White Board design. The White Board profiles change very little from generation. The materials improve, the quality improves and there are subtle design changes.

There was a sense of familiarity as the first EI Flex Distribution Graph formed as I measured the Riptide MX. I have seen this profile before, in fact it is an archetypical design. Successful on tour after a very, very long time, the profile is available from several shaft companies.

ACCRA iCWT Graphite Iron Shaft Review

The ACCRA iCWT iron shafts are unique. They are constant weight sets with 4″ parallel tips. A golf club builder, by cutting away some of the tip, can created the stiffness they want. The ACCRA iCWT is available in three weights, 75g, 95g and 115g.
