The 2023 Fujikura Axiom is a new iron shaft concept. They are parallel 0.370 tips which Fujikura states can be sanded to 0.355 tapers. The wall thickness at the tip is thick and I have no reason to doubt this can be done without damaging the tip integrity. Typically parallel sets are made from a single “blank” tip trimmed to increase stiffness in shorter lengths. The Axiom comes in three different models, short for 8, 9, W, mid for 5, 6, 7, and long for 2, 3, and 4. The idea is to create “specific performance throughout the iron set.” Lets see how this can be seen by virtual trimming a set of shafts.

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.
