Whether they're a blade, cavity back, or hybrid, almost all irons are either forged or casted. Grismont 3D Printed Irons are neither, and as a result have some of the most interesting designs we've ever seen. Designed in collaboration with Parisian artists Linlin and Pierre-Yves Jacques, the lineup includes the Ori, inspired by Moucharabieh architecture, and the Cés, which draws on Asian sculpture. The most interesting of the trio, however, is the Air, which has a lattice-like see-through back. All three designs are possible only because of the company's 3D printing process, and include game-improvement cavities that make them easier to hit. They're made in highly limited quantities, and can be orded as a 1, 2, or 3 iron.
