GolfWRX Insider: Inside the development of Rickie Fowler’s Cobra irons (plus full specs)
It’s been nearly 10 years since Rickie Fowler showed up on a PGA Tour driving range with Cobra blades in the bag. He was coming off of a 2010 rookie campaign that immediately put the young Californian into every big golf conversation there was to be had. Its been fun looking back at the work that has been done thus far, but oh my, did they go into a rabbit hole on this project.
On Sunday, Fowler will debut a set of the most unique forgings I’ve seen in a long time…maybe ever. The Cobra Golf Rev33 (33rd revision) muscleback irons are the brainchild of Cobra R&D, Director of Tour Operations Ben Schomin and Rickie Fowler. As you can see in the photos, getting here took some serious engineering chops and a lot of Rickie’s imagination.
The development process of the Rev33 took place over a year, from late 2018 to late 2019, and in that time Cobra R&D, Fowler, and Schomin had one goal in mind—make an iron designed with Rickie Fowler that inspired confidence in Rickie Fowler.
I had a chance to chat with Cobra’s Director of Tour Operations Ben Schomin on the development of the Rev33, and this is what he had to say.
JW: This isn’t the first time you have collaborated with Rickie on a Cobra iron. What made this experience feel different?

“Initial impression is that these wedges are very clean and high quality in appearance. They have a durable-looking satin finish, and the cavity back insert blends nicely with the steel; you barely notice that it’s an insert. Shafts and ferrules are pristine. The stock Lamkin Crossline grips are more rubbery than the tour velvets I’m used to, but the tread pattern gives a nice locked-in feel. The face milling is very pronounced, and the grooves feel ridiculously sharp. They are quite chunky from the back. The soles are big and wide, with a lot of leading and trailing edge relief. If you’re a digger with wedges, you are going to love these things. Comparing the soles and overall profile to my Vokeys, the difference is most obvious on the 54*. The CBX4 sole is much wider than anything I’ve played in this loft range before. While they’re both S-grinds, the CBX4 grind is much more pronounced on both the leading and trailing edge.”
“Flip the wedges over to the normal address position and it’s a totally different story. You would never know there’s so much sole and tech behind this club! While the topline is slightly thicker on the CBX4, I was pleasantly surprised that the appearance is much more “player” oriented than I would have thought. They don’t feel nearly as big here. The only thing I notice at address is that the CBX4 leading edge sits a little higher, because of that leading edge relief…”
“The other thing you’ll notice at address is the milling and groove pattern of the wedges. The HydraZip face technology is really cool to see and feel. Just rubbing your fingers across the face of the wedge, you know these are going to shred some ball covers! Zooming in on the grooves themselves is even more impressive, with a slightly different pattern between the low and high lofts:
…”My practice areas are sandy and the balls are hard as a rock, but I haven’t noticed any wear whatsoever on the wedge faces yet. Still spinning great, they really grab the ball.
…”These wedges like to be played square. Just line it up, focus on making reasonably clean contact, and you’ll be rewarded with a consistent flight and great spin.”
…”Today I put the Cleveland’s back in the bag for a rainy round. It started off drizzling and was just absolutely pouring by about the 5th hole. I was extremely impressed with the amount of spin I was able to generate with the CBX4’s. I found myself needing to adjust and fire at the pin much more than with my Vokeys; I was getting one hop stops, even in a heavy downpour.”
@ALTSean
“I got the wedges out for another round this morning. It’s been raining and warm here in NOVA so the conditions are on the softer side at the moment and the forgiveness of the soles shines in these kind of conditions. We don’t ever really get super firm or fast conditions so the extra bounce and size of the soles probably will work well here year round.”
@awtryau89
“As you can see, these wedges have some serious grinds. The pre-worn leading edge is on the 54 & 60. Even though these are larger than my Vokeys, they can be manipulated to hit any shot you like.”
“Looks are subjective but these look great. No real offset and not too rounded. They are on the larger side but unless you put them next to a smaller wedge, you’d never know they are a bit on the large side.”
“Feel is really good for cast and cavity back. They have a sharp click and aren’t muted but feel solid. The shafts are KBS Hi Rev 2.0. I play KBS C Taper Lite 110s in my irons so these mesh very well. Overall the pairing of the shafts and heads work very well. You won’t mistake them for soft forgings but overall they are softer feeling than my SM 9 KBS Tour 130 wedges.”
“Spin is exceptional. My Vokeys aren’t old but these definitely have much more bite than the SM9s. The hydro treatment is real. We played very soggy fairways and the spin I saw was crazy. One hop and stop pitches from short distances were the norm. It will be interesting to see what they offer when our course drys out.”
“Forgiveness is what these wedges are all about. I didn’t have any bad misses today that the wedges saved me strokes but I did notice some shots that weren’t perfect ended up being a good bit closer to pin high than expected.”
“Played again today and basically learned these wedges are a cheat code out of bunkers. So easy to hit any shot. I hit it close 2-3 times green side but my best shot may have been from a fairway bunker 127 out, up against a lip, with the 50 degree. Hit it to about 12 feet and promptly 3 putted. Oh well.”
“These wedges have stayed in my bag. Having played Vokeys for so long, I had to convince myself to commit for a while and put the ego aside. One big thing that has stood out to me is full shots and the better results I have seen there. These wedges offer so much more forgiveness that I have to be careful. I’ve had to adjust my yardages since they just play longer. I even took them to have the lofts checked because I thought they were strong and they were spot on so its just helping the ball go farther on those slight misses around the face.”
“I’ve stated they are just so easy out of the sand. I have hit some great shots and even holed out a few times from bunkers. I have to be careful on wet sand with the larger surface area on the soles but overall they just make the game easier.”
“Chipping is also so easy. I go against the grain so many times playing on Bermuda and the pre-worn leading edge just helps the wedge from sticking. I work very hard on shaft lean and keeping the hands ahead while chipping. The leading edge helps me play square face shots this way but you can also open them up.”
“I’ve had playing partners comment on my short game a few times the last few weeks and then ask to look at my wedges. Every one of them are surprised. I play to a 7 but one of my buddies who is a 1 has had some chipping issues lately and he started playing out of my bag one round. He plays ZipCores and probably won’t let his ego buy some but he had to admit he hit some of his best chips and shots with them. Great wedges for the common man.”
@vsabre
“Wedges arrived well packaged and perfect to the requested spec…super clean look and very appealing over the ball.”
“Performance – Range 3/4 Swings…Our practice range turf is slightly sandy from continuous repair with tight lies that are not forgiving for either chunky or blade swings. A really good wedge test and the CBX4s did not disappoint. For not having touched a club for two weeks the CBX4s were incredibly easy to hit. Like cheat code easy to hit as someone else mentioned.”
“Over to the practice green and hit a variety of shots with each wedge and honestly it’s nearly impossible to chunk one (which I can do from time to time). Soft feel coming off the club and I had forgotten what great wedges Cleveland makes, and of course, having a consistent fit spec through the entire iron set makes a huge difference. I will say we’ll see how they fare on tighter, firmer lies around the greens as we approach summer.”
“They will be staying in the bag and I’m sure I’ll be adding a 60 in the next few weeks with the same specs.”
@rbilramz
“My first impression upon receiving the CBX4 was how much cleaner they looked than the previous version. The lack of black plastic badging really makes them look more like players’ irons. I don’t have the CBX3 to compare them with, but I think the footprint is smaller than the previous generation.”
“The comparison to my RTX6 is interesting as well. The CBX4 clearly has a much larger and more rounded sole and bounce. However, from the address, the size difference is pretty minimal. They both frame the ball nicely without looking oversized. I can also manipulate CBX4 in my hand really easily; the sole doesn’t cause any issues with the turf.”
“I am lucky to have a simulator in my basement (Foresight GCQuad) and a putting/chipping green in my backyard. This is where my first round of testing occurred. I started at the putting green, rotating between each club. I do 90% of my chipping with my 54, but I hit a few with all of them. There was an immediate improvement with the CBX4, as poor turf interaction was not punished as much. My putting green isn’t very large (not enough space for any pitches), so I quickly made my way to the basement.”
“After getting warmed up, I compared each club against my current gamer with 12 full-swing shots. I would throw away the worst 2 and then average the remaining. The results here kind of surprised me. Despite identical specs, the CBX4 was consistently 2-3 yards (or more) further than the RTX6. I was expecting more forgiveness and consistency but not additional distance. I should add that I am not looking for any additional distance either, I like my current gapping. I am guessing the distance is due to increased forgiveness as I rarely hit the ball in the exact center of the face.”
“Spin numbers were basically identical. There wasn’t enough difference between the two for any conclusion to be made. The lowest ones were around 8,000rpm with the 48 degree and consistently around 10,000rpm with the 54 and 60 degrees. The UtilZip grooves and face milling really work great. I wouldn’t have any problem stopping and even backing shots up with these wedges.”
“The dispersion of the CBX4s was a little tighter, but not drastically. On good strikes, they were probably identical. The only noticeable difference came on really bad strikes, where the additional stability of the CBX4 became obvious. It won’t save you from a bad strike, but the CBX4 stayed a little straighter and went farther when I put a bad swing on them. I was slightly surprised by this, as I expected the difference to be larger. I guess the shorter distances of wedges make the forgiveness less obvious.”
“Distance/spin/dispersion aside, it would be impossible to ignore the difference in feel between the RTX6 and CBX4. On good strikes, the RTX6 simply feels amazing. It’s very solid while equally soft. I think that’s the feeling that people love about traditional wedges. I don’t have a problem with the feeling of the CBX4, but it’s just not as pure. It is clearly a cavity-back feeling. Feel isn’t overly important to me, so I wouldn’t have a problem with that. I just want to point it out.”
“My next test was taking them to the course and getting real-world impressions. Before playing, I put the wedges through a pretty decent warm-up that included full swing, pitches, chips, and a bunch of sand shots. This is where the CBX4 shined for me. Off of imperfect lies and out of the sand, the more forgiving sole was impossible to ignore. I headed to the Par 3 course at Green Valley Ranch to put them both into action. I didn’t keep score because I wanted to hit basically every shot with both clubs, and putting shouldn’t matter. The par 3 course at GVR is short, but it is NOT easy. By starting every hole with two balls, and then hitting every subsequent shot with each wedge, I was able to get a pretty good comparison between the two. In the end, the CBX4 simply performed better for me. And by the last few holes, I was noticeably more confident over the ball with the CBX4. That may be the largest benefit for me. I simply approached tough angles or bad lies with less apprehension. I was less afraid of hitting it fat or blading a chip.”
“Long story short, I may be the ideal player for the CBX4 wedges. The 54 and 60 degree clubs are securely in my bag. I am going to stick with the ZX5 A wedge over the CBX4 48, but that’s mostly due to my preference to have my gap wedge match my irons. I almost always use it for full-swing shots, so I like them to match. The cavity back design adds some forgiveness (and distance?) on full-swing shots, but the real difference for me comes around the green. The sole design is simply easier to work with. No question about it. I truly recommend the CBX4 to anyone who struggles with their short game. At least for me, my biggest inclination to use them historically has been based on pride. The improved looks make that easier to get past, but the improved playability makes it impossible to ignore. I am deeply on team CBX for now.”
Bonus comment
“We played this afternoon after getting about 4 inches of rain yesterday and late night. It was soggy. These wedges are forgiving and the tagline “chunk a little less” is real. Today was a good day to have more forgiving wedges.” – @awtryau89

FINALLY we get an answer on when Cobra is releasing a new MB. I LOVE LOVE LOVE the current MBs but as a gear junkie ever since they had this new “Rickie Proto” ive been wanting a set. Gonna have to order a set of the new ones and probably an extra set of the current model if they drop the price to move old stock. Thank you for this article!!

It took cobra a year to rip of the p7tw? From the inspiration (mp14/29), look, to the milling, to the tungsten plugs? You would think in a year you could have came up with something unique. I would label this a shank but it’s really more just diarrhea.
Guy who actualy pays attention to detail
May 15, 2020 at 11:01 am
Ricky has had a tungsten plug in his irons for many years, so nothing new there. Tungsten in irons has been going on for quite a while in general (Ping S56 from 2011, first Ap2 irons from way back). Also, how is it ripping off when they are both ripping off older irons? This iron honestly looks nothing like the P7tw. Your “Shank” comment, Ironically, these would be the first irons ever made that could shank relatively straight because they milled the par area and hosel flat to remove the offset look. I’m not even sure what would happen on a hosel shot.
Craig
May 15, 2020 at 10:23 pm
Um, no. It is well known Tiger likes a little bit of offset and longer blade. These are almost the opposite, zero offset and tiny blade.

The 304 Stainless is interesting. I’ve heard they need to be checked frequently as they go out of spec for loft and lie very easily with use. No problem for Fowler, but it could be an issue for the consumer.

I’m sure those that are inclined will get them checked, otherwise they’ll be just like other clubs that “wander” around though use.

These are amazing clubs. Hope they bring something like them to retail. What’s the deal with the grips? (non-brushed RF style)
