The grindworks MB-1 FORGED is a small muscle back iron designed for players who appreciate beautiful lines and soft feel. Control, stability and accuracy are all strong points of this precision forged S20C iron.

Inspired by legends such as the Spalding Top Flite Professional and Bridgestone J’s Professional Weapon among others, the MB1-FORGED is a modern evolution of design, materials and manufacturing. Our designer and technical advisor worked hand in hand together from pencil drawings to CAD, and from resin samples to forging molds, to test samples to final products. A process spanning nearly a year of revisions, testing, alterations and even more testing before reaching the final product.

The curved and stepped design of the MB1-FORGED allows us to gradually move the center of gravity from lower to higher as the irons progress from long to short, a  feature we have dubbed Dynamic Gravity Progression.

DGP helps each iron perform more inline with what it is intended to do, for example, the 4 iron has the lowest CG making it easier to launch the ball in the air and get more distance. The mid irons 5, 6 and 7 irons, have a a slightly raised CG to balance launch and distance as well as control and accuracy. The short irons, 8, 9 and PW have a raised CG which create a much more stable trajectory and more spin allowing a player to aim at the pin with more accuracy and spin control.
