The designer of Jumbo Ozaki's putter Mr. Masuda discussed golf club design with Kronos Golf's designer Phillip Lapuz in Buzz Golf magazine's exclusive interview in the April 2014 vol 30 issue.
The article is in Japanese; however, the take away points are evident in the pictures alone. The two discuss the importance of milling and maintaining straight lines to aid in alignment. The straight edges help the golfer know where they face is and can feel more confident in their set up.
We hope to translate these articles in the future so that people in the US can also enjoy these exclusive interviews. For updates please feel free to add yourself to the mailing list.
