BRIEF:

Create an iron that is superior in distance and controllability to any other iron on the market

Accuracy:

To optimise the accuracy and playability the head needs to be neutrally, dynamically, balanced. This means as the clubs head arrives at impact the weight is still evenly distributed despite travelling at high speeds. The below prototype was hand crafted modelled on digital images. At this stage the samples are made in pieces using available materials, it is a good way of knowing how the club will look at address also if there are any issues only a small part of the club will need to be remade rather than the whole sample.

Image 1 sample was found to be too light in the toe and so a copper plug was added to increase the toe weight by 3 grams (image 2).

When the weighting was finalised the brass master is produced, the brass master is an final blue print that is constantly referred to throughout production. Is it also made from purer materials and confirms the weighting measurements are correct, up until this stage prototypes have not been made from pure materials.

Now perfect balance of the iron has been achieved the playability is assured and the distance aspect of the design can be worked on. Through research we found the best way to achieve explosive distance was to reduce the thickness of the face creating higher COR, however this method is not without its hidden dangers.

A thinner material will flex more at impact and over time can weaken, to ensure that there were no issues we hired a cannon test facility which allowed us to fire a golf ball at the face 24/7 to ensure that there would not be any problems with longevity. From this testing we found 2.2 mm to be the optimum thickness of the face and the perfect material for this would be 17-4 precipitation hardened stainless steel which offered feel and high performance.
