One Setup One Swing


Proper setup includes foot positioning, spine angle and ball position, and many other variables. These variables change as you switch between longer and shorter length clubs, causing more room for error. With one setup and one swing you can simplify the entire process. Every player has their favorite club and for many, it's a 7-iron. With COBRA's One Length irons, you will find new confidence in your game, allowing you to play any iron in the bag as if it were your trusty 7-iron.


One swing for all of your shots

Long irons for more consistent distance

Tighter shot dispersion on approach

Short game accuracy improvement


The KING™ F7 ONE Length™ irons make their debut as COBRA’s first ever single-length iron set. Inspired by our relationship with PGA TOUR Professional, Bryson DeChambeau, The KING F7 ONE utilizes the same TECFLO constructions as the KING F7 along with PWRSHELL™ Faces and Precision Milled Grooves. However, the KING F7 ONE features constant 7-iron lengths throughout the set and each head has been re-engineered for proper geometry to deliver optimized trajectory and distance gapping from long irons to wedges. The end result? A simpler, easier way to play.

Never Targeted Pins so much, unbelievable
Review by Neill One Length - 9/12/2018

Been thinking about getting a set for a while, finally got a set at the start of this season, I have never written so many birdies on my score card, these things are pin hunters, my buddies can’t believe how much difference they have made. If your thinking of trying them do it you won’t look back.

KING F7 One Length Irons Measures Up
Review by Rick - 7/22/2018

Before I switched to my F7's, I played the Cobra irons. By far, the best club in my bag was my 7-iron! I could three-finger it to 145-150 yards or I could close it down a bit for a 180 yard shot. When I heard that the King F7's were all at 7-iron length, for me it was a no-brainer. I love my F7's and the new found trajectory that comes with them! Which is cool, because now that I'm 56, it's unlikely that I'll be buying anymore irons - oh wait, I will be buying one more club - I need a F7 4-iron to complete my set!

Review by Maddaddy - 6/12/2018

I let the sales guy talk me out of the wedges when I first bought the set last year. After switching it’s changed the short game. I was really frustrated and regretted listening to the sales guy. If you have the one set it helps to have all the clubs.

Best irons yet
Review by ManiacVandal - 5/30/2018

I have had single length irons for years. I have two sets for 1-Iron golf and while I like them these new Cobra irons are better. I find them to be more forgiving and longer then my previous sets. I guess everyone is catching on to the best kept secret in golf.
PS... Your grips are too small and tapered grips make no sense.

Cobra F7 One Length
Review by Jerry L - 5/21/2018

These clubs have really improved my game. Probably have taken 10 strokesoff my scorecard. Being able to utilize the same swing for each club is the answer. Thanks for making a great product.

great irons
Review by papajoe - 5/16/2018

Ready to quit last year, from over swinging my clubs. Friend turned me on to one length, and he said his accuracy on all irons improved. I bought a set of f7's. I never missed a green from 120 in, my last round, My longer irons were all crisp, and either on the green or within 10 yards. First year in many years that I'm looking forward to playing. Swinging easier with all clubs has really helped.

Awesome clubs
Review by Zigzaggary - 5/2/2018

Im an 16 handicap player. I have a 4-9 set in 9 iron length. I really like the one length, GREAT idea. Its helped improve my confidence in my iron swing, i just think 9 iron and I get good contact. The only problem is that the 4 iron with such a short shaft doesnt fly very far, it only carries 200 max for me.

F7 one length irons
Review by Charlie - 4/17/2018

I have been really pleased my F7 one length irons, playing with one arm and some balance issues, they seemed to help. I have taken them to our challenge golf course and letting others try them, we all like the senior shaft and mid size grips. Thanks for letting us order single clubs, helps to try them before ordering a full set, I'll be ordering more.

Best 4 iron ever
Review by Big Dave - 4/17/2018

I’ve only had the clubs a short time but they are awesome. The one length truly makes a difference in my game. I’ve always struggled with long iron as most of us high handicap guys do. Not anymore. Early normal swing and I can launch my 4 and 5 irons. The shorter irons and wedges do have a high ball flight but the steep decent helps me stick shots on the green. Great product for anyone looking to give themselves a boost and try something different.

F7 One
Review by Doog - 3/23/2018

I purchased these in regular graphite. I have always hit my 6 and 7 irons best. The concept that all my irons would be the length of my current 6 iron was intriguing. I took them out for the first time today and loved them. I played from the gold tees and hit the 5 iron off the tee on most holes. I’ve suffered from lover back problems in the last few years, so I went with the regular graphite. I wished I’d have done it a long time ago. I was almost two clubs longer and a lot straighter. The 5,6,7,8,9 irons are money. It’s gonna take a little time to get used to half shots with the wedges, hitting them is not the problem, figuring out new distances is.

Cobra King F7 One Length 4/5/6 Irons
Review by Tom - 2/27/2018

I've been inconsistent with my long irons and finally accepted that a change was in order. My 7 iron(F6 variable) has always been my most reliable iron. So trying one length 4/5/6's seemed a logical choice. I'm so glad I have made this change. While losing a few yards in distance, my ball striking is spot-on with pretty much every swing and my accuracy has improved. I was actually surprised how naturally the transition happened. I reluctantly opted for the Fujikura graphite shafts for the lighter swing weight. I've tried this shaft with my driver and was unimpressed. But they seem to work really well with shorter clubs.... All in all I am very happy with these one length irons.

Not to bad!!
Review by WestTexasGolfer - 2/19/2018

I was really skeptical, I have stopped playing for a couple years and decided to get back into it and decided why not buy a set of irons, researched came across these, man i did not know if i was crazy or not but I have always thought since i was young why not have the ball and my set up in one spot all the time, it would make it so much easier! well today i got to test them after receiving them saturday. First off i should have hit some balls before hand, i just went cold turkey and man i sure as surprised! I missed the sweet spot about 95% of the time but i attribute that to never hitting them except on the course, BUT every shot that seem to miss hit was still pretty straight and didnt think i lost much distance either! Now for the good, man i was using the GW a lot around the green, took a lot of getting used to, but two straight holes one from 30yards and one from 15yards i holed for birdie! Lets just say i am sold lol cant wait to hit them more and hopefully improve more like everyone else has said!

Best clubs ever
Review by Tampa Richman - 1/28/2018

Just started relearning the game with Ben Hogan fundamentals book. Had issues with short irons. First round ever with F7s and my buddies could not believe how much I improved in the 2 weeks I had the clubs. They say I hit them with the heimmmm. Babby Booie to all.

Review by Terrance - 11/19/2017

I had a stroke a couple years back and took some time off from golf.Now that I'm back was having iron troubles.I played a demo set and loved them.I bought a set soon after.I've dropped 5 strokes off my handicap since.I've ordered the 4 Iron and will add the SW soon.I couldn't be happier. Thanks Cobra

2nd that motion!
Review by Proof - 8/19/2017

Received clubs yesterday and played 18 this a.m. Hit the 4, 5, 6 clubs with the thought and set up of a 7 iron. All hits were flush and with the added distance. I have removed the 4&5 hybrids from my bag. Maybe put them up for sale. Right on "Cobragolf"!

Wish you offered a 3 iron!
Review by Bundy4275 - 7/17/2017

I'm really enjoying these so far. I wanted to simplify my swing as a recreational golfer. They are very easy to hit. My only wish is that you offered a 3 iron.

Great irons
Review by Coltsfanjoe - 6/18/2017

Cobra one length is damn good set of irons

Wish they had come out 20 years ago.
Review by Happy Golfer - 6/5/2017

Simply the one length clubs are awesome as a scratch handicap I worried about hitting them a mile in the air. The clubs with the kbs tour flight shaft are truly amazing the ball flight is mid I can move it up and hit it high. 2 rounds with them and I'm hooked. Waiting for a 3iron and a sandwedge to come out. Try these clubs you will be impressed!!!

Great for beginners
Review by jon - 6/3/2017

Started golfing about 6 months ago with an old set of clubs my father in law let me borrow. After falling in love with the game I decided to buy my own clubs. After some serious consistency issues with long irons I decided to give these clubs a try. I can say that I honestly hit the ball incredibly well 90% of the time with these. Once you learn how to make a proper swing with a 7 iron you are set. My golf instructor even likes to hit them when I take lessons. He likes the the idea of not having to bend over as much with a wedge as he has back issues.

F7 irons
Review by John - 5/31/2017

I've had these irons about a month now and I lovem!! I'm hitting every club longer and straighter. The 7 iron was by far my best iron before I got these. So hitting a 7 iron length every club is great. I'm hitting my 5 iron between 220-230. I dropped my 5 wood and I'm thinking about getting a 4 iron

Very Happy
Review by Bret - 5/15/2017

First off I am a 22 handicap. I have never been able to hit long irons and my driver is pretty bad most of the time. I pre-ordered these clubs as I waited for them to come out. I am very happy with them. I don't even use my driver anymore as I can hit the 4 iron a long way when I swing it right. My longest 4 iron shot was 228 yds and about sent me into shock. Of course I don't always hit it that long but I'll take 180-200 down the fairway most of the time rather than sending my driver shots to who knows where. I do find that my distances are longer on every club than I was used to before, so that has taken some adjustment, but a good problem to have. While these clubs won't fix bad habits, they have helped me to enjoy golf again and have lowered my scores due to being able to use a 7 iron swing.

Review by Markku - 5/15/2017

Easy to hit very nice looking clubs. Online one round played feelngi good

Review by WalterJ - 5/12/2017

I'm so in love with these clubs! I'm hitting my 4 iron as far as some guys are hitting there 3 wood!! Really I'm hitting my irons straighter and about 15 to 25 yards further than my Titleist clubs I have before these! I've been playing almost 3 years now and was shooting in the 90s and now I'm constantly in the 80s. "INCREDIBLE the same swing for every club is a golfers dream."

Finally, equipment improved my game.
Review by Mike K - 5/10/2017

Played club demos, 5-GW, for 6 rounds,then bought them. My iron game improved unbelievably. My previous clubs were Cobra Amps. I hit the one lengths straighter, higher, and longer. Same set up for every shot, 5-GW. After 4 weeks, since I was hitting the 5 so well, I ordered and received a 4 iron. I hit the 4 straight and long. I have dumped all my hybrids. I am now going to order the SW. Over 20 years of buying irons, wedges, and drivers, I usually only saw slight improvement, and questioned spending the $$. This iron set made a major improvement, and is the best money I've ever spent on golf equipment. I am 64, and a 16 handicap. I was an 18 seven weeks ago when I started hitting these clubs. Note: I did go with graphite shafts. My Amps were steel.

Same old thing over and over
Review by George - 3/8/2017

Great concept to bring back to golf. We practice and practice to groove in the same swing. Went to the course with at the end of the season ready to put my 5 iron away after consistency issues. Now that I have the Cobra One Length the 5 will stay in the bag. It's as easy to hit as my 8 iron. In fact all the clubs are as easy to hit as my 8 iron. Great job Cobra

Review by 2grouse - 2/16/2017

Bought a set of one length, and got my long iron distance back. I'm 70 years old and thought that it would never happen.

Honest Review
Review by Hcjr - 2/12/2017

69 years old, play to 6-9 handicap, one plane swing, best round 64. Need to simplify my swing due to age. Purchased clubs Feb . 8, 2017, played two rounds shot 75-76.
Plus; comfortable at setup, consistent strike, flies well even on miss-hits, plenty of distance, no loss of distance on 6-5 iron, attractive build and good grip. Shocking how well the longer clubs play on shots around green.
Con; you will need to adjust to both wedges on full shots.
Very satisfied with product.

Dramatic Improvement
Review by Vtgolfer - 1/30/2017

I can't not wait to get these clubs outdoors!! Just the few times I have used these indoors at the simulators, what an improvement I noticed. I gained overall distance and consistency. The feel of these clubs are remarkable. I'm only a second year player but the way I hit these clubs, they make me feel like a seasoned pro!! Thank you Cobra

Great clubs !!!
Review by Andy - 1/28/2017

Been waiting for these clubs for about a year. Ball really jumps off the face. Playing a One Length club allows you to repeat the same swing over and over again. Give them a try if you ever get a chance. Straighter shots and on average closer to the pin once you're on the green. You'll probably still need a couple of shorter wedges around the green.
