Forgiveness40

Rated highest for workability and feel; its softest dimension is forgiveness.

Best for

A 0-8 HCP shotmaker at 90-120mph who wants pure muscleback workability + premium feel with a measurable hint of mishit protection — and accepts the ~£310-per-stick premium for the 3D-printed lattice tech.

Avoid if

You need GI/PD forgiveness, you want to feel a forged 1025 carbon steel (Mizuno Pro 241 / Titleist 620 MB are still forged), you want longer-loft distance (use a PD iron), or the acoustic matters as much as the feel.

Pros

  • Blades simply shouldn't be this forgiving — class-leading blade mishit protection via 3D-printed lattice + tungsten heel/toe
  • Buttery soft 316 stainless feel — up there with the very best forged Mizuno/PING/Titleist blades
  • Smallest MB shape with highest possible MOI — workability + just-enough forgiveness
  • 3D-printed precision fine-tunes CG + acoustics + damping without a face insert

Cons

  • Acoustics didn't match the pleasing ball flight — sound flagged as weak dimension
  • ~£1,900 for a 6-iron set (~£310 per stick) — eye-watering premium pricing
  • Launch monitor data won't blow anyone away — traditional 34° loft trades raw distance for blade purity
  • Cast 316 stainless steel (not forged) — feel comparisons aside, construction is different

By dimension

40

Forgiveness

Modest

Blades simply shouldn't be this forgiving — explicit reviewer verdict. A confidence-inspiring players iron with a Goldilocks size — slightly larger than MBs — delivering cavity-back-like forgiveness + off-center strikes stayed surprisingly consistent. 3D-printed internal lattice core allows weight redistribution via tungsten heel + toe — essentially creates perimeter weighting to boost playability. Because of the tungsten weighting, 3DP MBs have a lower CG than typical blades and launch higher. Average forgiveness for a blade — class-leading blade mishit protection thanks to 3D-printed lattice + tungsten heel/toe perimeter weighting.

78

Distance

Strong

7-iron sits at a traditional 34° loft — blade-typical. Launch monitor data from a Foresight Sports GC3 showed numbers that won't blow anyone away, which is exactly what you would expect from a conservatively lofted set of blades. Because of the tungsten weighting, 3DP MBs have a lower CG than typical blades and launch higher than typical MBs. 3D-printed 316 stainless steel (cast process, not forged). Average distance for muscleback category — traditional 34° loft + 316 stainless construction trade raw distance for blade purity.

94

Workability

Class-leading

Smallest muscle back blade shape infused with highest MOI possible, while retaining player-preferred feel and precision. All the workability and feel of a true blade while adding just a hint of forgiveness + easy shot-shaping. HL testers noted easy shot-shaping; off-center strikes stayed surprisingly consistent. Compact blade aimed at better players and low-handicap golfers + 3D-printed precision allows tour-CG tuning per club. 3DP MB is based on the shaping of the King MB irons. Top-tier workability — pure muscleback shape with 3D-printed CG precision + traditional 34° loft + heel/toe tungsten gives shotmakers complete control over flight.

92

Feel

Class-leading

Buttery soft, offering excellent feedback that lets you know exactly where you struck the ball without being unduly punishing + the feel produced by the 3DP MB's 316 stainless steel is incredible, and up there with the very best forged irons from the likes of Mizuno, PING and Titleist. Lattice structure printed inside the head also enhances the sound and feel, making it soft and responsive like a true MB iron. Unusually soft, solid feel on impact. One of the purest visuals and impact sensations in testing + a triumph of engineering and aesthetics. Top-tier feel — buttery soft 316 stainless impact via 3D-printed lattice damping; explicitly competitive with the best forged blades.

76

Sound

Strong

The acoustics didn't match the pleasing ball flight per HL testers — explicit acoustic weakness. 3D-printed internal lattice core allows Cobra to fine-tune the acoustics and dampen vibrations without using a face insert. Feel reviews praised soft impact but sound character less consistently praised than the feel. Below-average sound — Hot List testers flagged the acoustic as the weakest dimension despite the lattice-tuned damping.

90

Looks at address

Class-leading

Compact blade aimed at better players and low-handicap golfers. Goldilocks size — slightly larger than MBs silhouette inspiring confidence. Based on the shaping of the King MB irons — traditional tour blade lineage. Slightly thinner topline and a touch more offset than the King MB. One of the purest visuals... a triumph of engineering and aesthetics. Top-tier address looks for the blade category — purest visual in testing.
