Big Bertha B21 Irons

The First Big Bertha Iron Designed With A.I.

You're looking for more distance, and the Big Bertha B21 Irons are here to give it to you. In fact, we've designed our legendary Big Bertha shaping with a NEW formula for distance and forgiveness...any way swing it.

Features &

  • Fast Ball Speeds From The First A.I. Designed Big Bertha Irons
    High ball speeds and increased spin robustness from our industry-leading A.I Flash Face Cup. Ball speed is further enhanced by our 360 Face Cup that flexes and releases at impact.

  • Improved Turf Interaction From Legendary Big Bertha Shaping
    A club profile that's engineered to give you more confidence over the ball with noticeably wider soles. For easy launch, lower spin and straighter flight, we've added more offset into the head.

  • Easy Launch From Our Visible Tungsten Energy Core
    Now you can get higher launch conditions through the set. We've added a significant amount of custom tungsten weighted, so we can deepen the CG with extraordinary precision while still maintaining high ball speeds.

  • Pure Feel From Urethane Microspheres
    Our patented urethane microspheres comprehensively absorb unwanted vibration for exceptional feel, while also maintaining fast ball speeds.

Watch Video

Condition: Excellent

Clubs have seen minimal usage and are in top of the line preowned condition. You may see some minor or faint cosmetic blemishes (i.e. very light scuffing and/or scratching). Typical wear that you will see on an Excellent condition club is normal ball marks that are lightly visible on the face, minimal scratching to the crown, sole and edges. Shaft has no noticeable wear.
Watch Video

Condition: Very Good

Clubs have seen normal usage for an extended period of time or at least one season, the wear you’ll notice will be typical of the age of the model. All of the wear is purely cosmetic, and will not in any way affect the performance of the club. Typical wear you’ll see on a Very Good condition club is normal ball marks and scratching on the face, normal scratching on the sole, faint dings and nicks on the crown and/or around the edges of the head, light scratches, paint chips, paint blemishes on or around the crown.

Great shape for the age
January 15, 2021
The clubs are great and pretty clean for their age. Only problem is that they are like an inch short maybe more. I need all the distance I can get so I’ll be sharing these with another lucky player.
ProsClean. Great Cavity back. Smooth when struck well.
ConsShort shafts.

Not better then a Ping Driver
January 13, 2021
I have the 400 Max Ping driver , but am a huge Fan of Taylor made so though I'd switch or try a different driver. M6 has a very small sweet spot on the it. Wasn't a fan of her. So im sending it back. Ping all day

Driver looks good. Feels good. Nice swing weight. Haven't been able to get it on the outside to use. Too cold.

Good performance affordable price
January 7, 2021
I've had a chance to use my new (to me) value condition G25 hybrid a few times now, and am a fan of the performance from a variety of lies. Hit a fairway on a dogleg right I usually try driver and miss. Smooth contact from the short grass, the moderate rough, and even 180 yards out of a sand trap.
Prosall good things to say

What an excellent golf club from any lie whether a punch shot (under trees etc) back on to the fairway and/or back into play, from my experience, Tour Edge Exotic is THE golf club.
From the first hit I was impressed. It has provided another level to my golf game which in turn has added confidence.
Do yourself a favour, go and test hit one and I am sure you will buy one.
Highly recommend.
ProsGreat feel, good looks combined with a very good quality shaft as standard.
