We have seen carbon fiber shafts with outer wraps of stainless steel wire, here we have a shaft with in inner wrap. The Metal mesh technology is only in the tip of the shaft. This is not the first time Mitsubishi has integrated metal into their shaft prepreg. I have fond memories of the TINI wire used in the KuroKage shafts. Mitsubishi tells us the metal mesh added weight without having to add material which would have change the balance of the shafts. And like the TINI wire, the mesh adds a responsive straighten to the shaft. You will find the Mitsubishi MMT iron shafts offered as an upgrade by several of the major brands.

I have seen many shafts over the years with a woven material placed in the butt of shafts. This is as an indication that shaft manufactures recognize the thin walls near the but of the shaft deform and oval under load. The ovaling of the shaft in this area can contribute to shot dispersion. The woven Kevlar® material use by Mitsubishi is the only material I have measured to date where I can see a measurable effect. Hoop deformation significantly dips in this section of the shaft. Reduced hoop deformation in the 1K weave is the same as the CK weave. Mitsubishi tells us the 1K material transmits more feel.
