Our Verdict

If you’re a left-handed player looking for irons that offer both distance and forgiveness, the Big Bertha B21 irons are an excellent choice. Their design is incredibly user-friendly, especially for mid to high handicappers who need help launching the ball higher and straighter.

The standout feature is Callaway’s Flash Face Cup, which adds power and consistency to every club. While each iron has its own unique architecture, the performance is uniform across the set. You’ll notice fewer weak shots, even on off-centre strikes.

Another major benefit is the turf interaction. The wider soles and increased offset glide smoothly and help square the face at impact. This makes them especially helpful for players who tend to slice or struggle with inconsistent contact.

The addition of tungsten weighting isn’t just a gimmick—it plays a key role in keeping the centre of gravity low and deep, leading to easier launch and better trajectory. Combined with the urethane inserts, these irons strike a balance between power and playability.

In short, these irons feel stable, look confidence-inspiring at address, and make a noticeable difference in consistency and distance. For golfers who want to enjoy the game without overthinking mechanics, the B21 set delivers trusted Callaway performance at every level.
