Born from more than 30-years of composite shaft mastery, the new MMT Taper Iron utilizes a patent pending Metal Mesh Technology (MMT) to redefine the possibilities for feel and performance in a composite iron shaft. A unique metal mesh – made from individually braided strands of 304 Stainless Steel – is integrated into the shaft’s prepreg layers towards the tip. This improves density and stability, while also allowing for thinner overall composite wall construction. Together this yields a finely tuned, highly responsive shaft that still provides the consistent launch and spin control needed for effective iron play. This is for only 1 shaft. We have these in both taper and parallel. Installation options are available as well. The price of $100 if for a full iron set installation.
