i59 Forged Irons

DIFFERENT AT ITS CORE.

Crisp, consistent impact, a solid feel and a flighted trajectory with added forgiveness are the result of an aerospace-grade aluminum insert joined to a forged 1025 carbon steel body and forged 17-4 SS laser-cut face. To reduce fliers in the short irons and preserve spin in the long irons, the face is engineered with MicroMax™ grooves, combining steeper sidewalls with tighter spacing to allow four extra grooves. The Hydropearl 2.0 finish repels water for predictable, consistent performance from wet and dry conditions.

THREE-PIECE FORGED DESIGN

Aerospace-grade aluminum core (1/3 density of stainless steel) combines with 1025 carbon steel body and 17-4 SS laser cut face to ensure trajectory control and precise shot-making.

ALUMICORE^™ TECHNOLOGY

An aerospace-grade aluminum insert (1/3 the density of stainless steel) saves approximately 30 grams of material, allowing for tungsten toe and heel weights that elevate MOI to match that of the larger i210 iron, achieving a level forgiveness uncommon in a forged design. AlumiCore also contributes to the stable, solid feel at impact.

MICROMAX GROOVES

The fully machined face has new MicroMax™ grooves, combining steeper sidewalls with tighter spacing to accommodate four extra grooves for reducing fliers in the short irons and preserving spin in the long irons.
