Design Details
The Maltby TS1 IM (Injected Muscle) Forged Irons are a true billet forged 3 piece iron design that delivers performance and feel unlike any other muscle back iron head. This incredible playability and direct feedback comes from a combination of a very low and centered vertical center of gravity, modern loft specifications, soft polymer material injected throughout the entire club head and a new 2.1mm Super Maraging steel face.


Revolutionary Construction
Forged using a Precision 5 Step Forging process for very precise parts requiring very little polishing to provide unparalleled specification tolerances. The TS1 IM head design features a 2.1mm Super Maraging steel forged face and a forged 1025C carbon steel body with an internal tungsten weight co-forged low and towards the toe inside the club head. The co-forged tungsten centers the vertical center of gravity location for a more stable head not typically found in a muscle back design. The pieces are then precision welded together leaving a void behind the entire club face that is injection filled with a proprietary polymer to enhance ball speeds and provide an exceptional feel on both center and off center hits.  


Superb Playability
The overall profile of the TS1 IM Forged Irons certainly give the appearance, both in the bag and in the playing position, of a traditional blade but offer Super Game Improvement (PF701+) playability performance throughout the entire set. With an actual MPF number approaching 800 points, the TS1 IM offers more forgiveness than the majority of game improvement and or cavity back irons

High Speed Super Maraging Steel Face

The TS1 IM face is forged from MS300 Super Maraging steel. MS300 is stronger than standard Maraging steel due to its superior elongation and yield strength allowing for a thinner, 2.1mm face thickness, resulting in higher ball speeds off of the club face. MS300 Maraging steel is a low carbon, nickel-cobalt-molybdenum high-temperature nickel alloy that produces a very soft feel.


TS1 IM vs Original TS1

  • MS300 high speed Maraging steel face for increased ball speeds vs. traditional carbon steel faces
  • Added polymer and co-forged tungsten toe weighting into the entire set for a more consistent feel and carry distances

  • Improved loft separation in the short irons and wedges for more consistent yardage gapping
  • Reduced progressive offsets throughout the set as preferred by better players
  • Cleaner looking aesthetics with an anti-glare Pearl Nickel Chrome finish



  • Model masters and tooling created using precision 3D CAD
