“The 301 MB - a traditional muscleback forged from soft S20C for elite ball-strikers. Rung-4 at a DTC price.”

Takomo's pure muscle-back blade, and the club most credited with turning the brand from a value curiosity into an enthusiast obsession. Forged in one piece from S20C steel with the thinnest top line Takomo has built, reviewers repeatedly put its feel alongside Titleist's 620 MB and Mizuno's Pro 221 -- 'maybe the Mizunos have a touch more forged softness... but the Takomos are easily 95% as good' -- at roughly a third of the price. It is unapologetically a blade: compact, thin-soled, minimal offset, and demanding of a centered strike, built for good ball-strikers who want maximum workability rather than a safety net.

Independent reviewers across multiple outlets (Driving Range Heroes, Bogey Book, National Club Golfer, Golf Sidekick, GolfReviewsGuide) converge on the same specific comparison -- direct feel parity with Titleist 620 MB and Mizuno Pro 221 at a third of the retail price -- the strongest, most repeated praise anywhere in Takomo's catalog. It is only 3-4 years old, too recent for the multi-year hunted-set pattern that defines a true cult classic like the Mizuno MP-32, so 'sleeper' (real enthusiast conviction that hasn't yet built mainstream or legacy recognition) is the honest label rather than overclaiming cult-classic status.

Skilled, consistent ball-strikers (low single-digit handicaps) who want workability and forged feedback over forgiveness, and who are shopping premium OEM blades like the Titleist 620 MB or Mizuno Pro 221 but want the same feel for roughly a third of the cost. Reviewers are blunt that 'most players will get better performance out of a cavity back' -- this is explicitly not a forgiveness play.

• One-piece S20C forging with the thinnest top line of any Takomo iron to date, described by reviewers as looking like 'a chef's knife' at address.
• Stock configuration ships with KBS Tour shafts and Lamkin Crossline grips, a players-oriented stock build rather than a generic steel default.
• Multiple reviewers make the identical direct comparison to Titleist 620 MB and Mizuno Pro 221, rating Takomo's feel at roughly 95% of those benchmarks for about a third of the price.
• Also sold as the short-iron half of the 301 Combo set (paired with the more forgiving 301 CB in the long irons) for golfers who want a blended bag rather than a full set of blades.
• Priced at $680 for a 4-PW steel set as of 2026, up from roughly $649.99 at the at-launch price captured in early 2022 reviews.

Launched in 2022 alongside the 301 CB as Takomo's top-of-line forged pairing, arriving as the DTC challenger-brand wave (Takomo, Sub70, Tour Edge) began pressuring premium OEM blade pricing the way earlier DTC waves had pressured game-improvement iron pricing a decade prior.

Peer-to-peer only, and thin supply given the model's youth and its devoted following -- clean sets rarely list far below Takomo's own $680 retail on SidelineSwap/eBay, unlike a 20-year-old blade that would have depreciated heavily. Expect roughly $500-650 for a well-cared-for set in 2026.
