“Straightforward 3/5/7/9-wood spread aimed at the same slower-swing member the Big Bertha name has always targeted — never a rung-2/3 candidate on strike data alone (R5).”
The B21 fairway wood was one-quarter of Callaway's 2021 push to send Big Bertha 'back to its super-game-improvement roots' after a decade of the name drifting toward mid-market. It paired an AI-designed Flash Face Cup (built on the existing 360 Face Cup) with Jailbreak bars borrowed straight from the driver line, wrapped in a shallow-faced, heavily offset head meant to launch high with almost no effort. Callaway stretched the lineup down to a 24-degree '9-wood,' an unusually steep option that let slower swingers replace long irons entirely rather than fight them. It shipped alongside the matching B21 driver, hybrid, and iron set as one coordinated anti-slice family, all built around the same AI-face marketing story that defined Callaway's whole 2021 catalog.
No collector interest or forum reverence attaches to this club — it is a well-liked, high-volume super-game-improvement fairway wood that did its job for slower-swing buyers and was superseded within Callaway's own line by the Rogue ST/Paradym-era fairways a couple of years later. Strong retailer star ratings (4.8-4.9/5 across Callaway.com, PGA Tour Superstore, Global Golf) reflect satisfied buyers, not scarcity or lasting cachet.
High handicappers and slower swing speeds (especially those who slice) who need real help launching long clubs off the turf; the 24-degree 9-wood option is aimed squarely at players who can't comfortably hit a 4- or 5-iron. Better ball-strikers wanting workability or a compact look should skip it.
Launched alongside the B21 driver, hybrid, and iron set in Callaway's 2021 'Big Bertha returns to SGI roots' reboot. It descends directly from the 2004 and 2014 Big Bertha fairways in this same catalog, and was itself succeeded within a couple of product cycles by Callaway's Rogue ST and Paradym-generation fairways using newer AI-face iterations.
Reviewers repeatedly called it among the easiest-to-launch fairway woods on the market: shallow face, generous offset, and a low-and-back CG built specifically to get the ball airborne from the deck. This is a maximum-forgiveness, maximum-launch tool by design, not a compromise — the trade-off is limited shot-shaping and a look at address some better players find bulky.
Calibrated across the whole catalog — a tour blade scores low here on purpose; it means control, not ease.
MSRP was $279. As a 2021 release with a mid-tier used-value band, complete units in good condition typically sell for roughly $110-$170 in 2026 depending on shaft and loft; well-worn examples or odd shaft/flex combinations run lower.
Reading is one thing — hitting is another. Book a bay and see the numbers for yourself before you buy anywhere.
