“A classic forged muscleback blade with a thin topline and tailored sole for maximum workability. A true blade for skilled ball strikers.”

The 588 Forged MB is Cleveland's true muscleback blade, launched in 2012 alongside the 588 Forged CB. Forged from 1025 carbon steel with the same laser-milled Tour Zip Grooves as its wedge siblings - including four intricate score lines etched between each groove for extra face roughness - it pairs minimal offset and a short blade length with an exclusive True Temper Tour Concept steel shaft, co-developed specifically for a lower, more penetrating flight. It was a notable move for a brand best known for wedges rather than iron blades, and reviewers consistently praised its classic look, soft forged feel, and total workability while flagging - unsurprisingly for a true blade - reduced forgiveness on mis-hits.

Genuinely well-regarded (a perfect 5/5 on golfreview.com, though from just three reviews) but under-the-radar relative to name-brand blades of its era - Cleveland's identity as a wedge company means this iron never got the attention a Mizuno or Titleist blade of equal quality would have received. It deserves more recognition among forged-blade shoppers than it gets, which is exactly the sleeper profile: real quality, thin market awareness.

Elite ball-strikers only - scratch or near-scratch players who want maximum workability and are willing to trade away forgiveness for control and feel. Anyone below a low single-digit handicap should look at the 588 CB instead.

• Uses an exclusive True Temper Tour Concept Steel shaft, co-developed by Cleveland and True Temper specifically for a lower, more penetrating ball flight.
• Minimal offset and short blade length give it a compact, tour-style address look.
• Shares Tour Zip Grooves and laser-milled face technology - including four extra score lines etched between grooves for added spin - with the 588 Forged wedges launched the same year.
• golfreview.com shows a perfect 5-out-of-5 user rating, though from a very small sample of three reviews, signaling niche devotion rather than broad popularity.
• Represented one of Cleveland's rare forays into a pure muscleback blade iron; the brand's volume and reputation have always centered on wedges.

Part of Cleveland's 2012 forged-iron relaunch, competing against the era's best blades: Mizuno's MP muscleback line, Titleist's 680/690 MB, and Ping's Anser Forged. A wedge-first brand fielding a true blade was itself a notable positioning statement.

Because Cleveland blades never built the resale demand that Miura, Mizuno or Titleist blades command, clean sets trade cheaply: roughly $120-$250 private-party for a 3/4-PW set in 2026, with single irons around $15-$30.
