Who are Muscle Back Irons for.

Muscle back irons are a halfway point between true blades and cavity back irons. Muscle back irons offer better forgiveness compared to blades but are less chunky than cavity back irons. Muscle Back irons tend to make an excellent choice for golfers who are good ball strikers, but want some extra forgives over a true bladed iron.

Phenomenal feel & feedback

5-Step 1025 forged carbon steel irons provide exceptional feel and feedback with every strike.

TECH OVERVIEW

5-STEP FORGED

While traditional irons utilize a 4 step forging process, the KING irons add a fifth step to deliver exceptional soft feel that better players demand. Each iron is crafted and 5-step forged from 1025 carbon steel for a more uniform grain structure and precise shaping.

TOUR INSPIRED SHAPING

The KING MB (and CB) irons feature the most compact shapes in the KING lineup, and are built with attributes that better players typically desire including thinner toplines for aesthetics, minimal offset for control, thinner soles for precise turf interaction, and shorter blade lengths for enhanced shot-shaping ability.
