Why is it called rev33? 

"We made 32 versions of a great iron, it took us 33 tries to make the perfect one"

- Rickie Fowler


Becoming one of the best players in the world means demanding more from yourself and your equipment. The RF Proto irons are a product of 33 revisions over the span of a year to create an iron that exemplifies the look, precision and performance that a great player like Rickie desires. Cobra's R&D and Tour team worked closely with Rickie every step of the way, taking his direction on the overall design to create an iron unlike any other.

RF Proto Bending


Each RF Proto iron is carefully crafted using a two step process: forged and machined for 155 minutes using a computer-numeric-controlled (CNC) milling machine to ensure the most precise iron without any inconsistencies.

RF Proto Iron Set


Careful consideration was taken to ensure every aspect of the shape ranging from the topline thickness, to each edge radius suited Rickie's eye. The design process began with Rickie hand shaping irons on a grinding wheel, and resulted in 33 different prototypes that were tested, and fine-tuned by Rickie himself. At first glance, one will notice the sharp edges and little to no offset that makes these irons strikingly different from anything played on Tour.

RF Proto Iron Tungsten Weighting

A high-density tungsten toe weight positions the CG right behind the hitting zone for the purest feeling shots with added stability on off-center hits.
