“We believe in letting the club do its job.” At Fourteen, we work hard day in and day out in order to bring the joy of golf to everyone out there. Here we introduce the club development process at Fourteen.

Aiming to make the impossible possible in a club, we start with a clear decision about what kind of abilities we want to endow the club with.　Rather than targeting a large number of people, we approach development with an individual golfer in mind, then work to repeatedly and thoroughly test and scrutinize the most cutting-edge technologies that promote our design goals.

The most important part of the actual club head production is the developing the basic design dimensions.　Firmly embracing the development concept, the club head dimension details, such as size, lie and loft angles, as well as sole width and face shape, are all based on extensive data collected over years of research.

We continue the construction of the club head by inputting the dimensions determined in Step 2 into our 3D CAD program. By simultaneously simulating the various club head dimensions, such as shape, center of gravity, and moment of inertia, we are able to achieve an even greater degree of fusion between design and function in the club head.

After completing the club head shape in our 3D CAD program, we use that as a base on which to make a resin model. It is absolutely necessary at this point to ensure a perfect head shape. This involves checking the resin model for details that do not show up in the computer model and making sure intangible cosmetic qualities of the club head meet expectations. We provide feedback to our 3D CAD program on any changes made and create a data set of increased precision.

A metal model is necessary for molding a finished product. In order to make that metal model, a copper and brass “master model” is required as a basis for the shape. We then go about manufacturing the club head, matching materials and construction methods with detailed balancing measures, and making gradual hand-refined adjustments based on the 3D data.

We commence thorough testing on the sample head created from our master model. This involves taking shape and center of gravity measurements and confirming that they match the original design calculations. A robot is used to confirm attributes such as strength and durability, and all performance testing is handled by actual human swinging of the club. By testing the club with a variety of individuals, we can gradually gain a good understanding of the club performance.
