Cobra King F6 irons: Progressively better
Along with a new line of King F6+ and F6 metal woods, Cobra is also launching new King F6 irons, which are engineered throughout the set to optimize performance for each individual iron.
The F6 has a progressive design that Cobra calls “TecFlo,” which stands for Technology Enhanced Cavity, Feel (and) Launch Optimization. More simply put, the long irons, mid irons and short irons each use a different type of construction to alter launch conditions.
See our in-hand photos and read about each of the different constructions in the F6 irons below.
Long irons (4-5), Full Hollow
The “full hollow” F6 long irons have what Cobra calls “T.O.P.” technology — a back cavity made from aluminum — which helped drop center of gravity of the hollow-cavity irons 1 millimeter compared to their predecessors, Cobra’s Fly-Z long irons. The construction saves approximately 10 grams of weight from the cavity, which allowed engineers to achieve the lower CG.
The F6 irons use milled V-grooves on their club faces, which produce approximately 200 rpm less spin than the U-grooves used on the Fly-Z irons, according to Cobra.
The benefits? Exactly what most golfers need from their long irons — a higher launch, less spin, more ball speed and more forgiveness.
Mid irons (6 and 7 irons), Half Hollow
The “half hollow” mid-irons also have T.O.P. technology, by way of an aluminum cap that sits between the face and the back cavity and helped save 5 grams of weight from the design. The mid-irons also boast a 1 millimeter-lower CG than their predecessors, the Fly-Z mid-irons.
The F6 mid-irons are designed with low CG’s and fast faces, but won’t be as high-launching as the full-hollow long irons.
Short irons (8-PW), Cavity Back
Cobra’s new irons have a gun metal finish with a chromed sole, making the irons pleasing to the eye, but yet the sole won’t lose its finish over time despite wear and tear.
The short irons have a deep undercut — a construction that helps boost forgiveness — while their milled faces and grooves help with trajectory control, according to Cobra.
Compared to the long and mid irons, the short irons will be the lowest-launching, highest-spinning irons in the progressive set.
A speed channel in the sole of the F6 irons is said to produce a higher launch, and more ball speed on mishits across the face.
Specialty (Gap wedge)
The specialty wedges have a solid, one-piece construction, much like you’d see from the majority of wedges that are sold separately from iron sets. According to Cobra, iron-like wedges just cannot provide the versatility most golfers need around the greens to play their best.
“We wanted the wedges in the set to look more like traditional wedges than irons” said Tom Olsavsky, head of R&D at Cobra.
Who should play the King F6 irons?
While better players may gravitate to Cobra’s King Forged CB/MB and King Forged Tec irons, the King F6 irons will best suit golfers with handicaps that range from 5-25 due to their designs.
Cobra’s new King F6 irons will be available for $799 (steel), and will be in stores on Jan. 15, 2016. Combo sets are also available, which come with six irons and two graphite-shafted King F6 hybrids. They sell for $899 with steel iron shafts, and $999 with graphite iron shafts.

Can’t wait to hit these sweeties! Been gaming the Bio Cells for 2 years and they still are great clubs….

I think I’d remove the sticker in the mid iron that goes across the bottom of the cavity. Looks cheap.

Love the designs Cobra has come out with this year. I could live without the orange but the irons have a very nice shape to them.

Paint fill is super easy to switch up (especially for a total nerd with plenty of time on their hands 😉 )…but that top line, my word. Those things are beefy.

Like the concept, hate the looks. Seriously, Is anyone other than Mizuno going to put out a CLEAN looking iron this season? Everything looks cheap and doctored up with color, finishes and fancy words like “TUNGSTEN”!

I don’t care what the look is if they work , just my opinion cause I’ve bought beautiful clubs that didn’t work , but m old Wilson FG-17 blades had it all

I like the concept, I need higher launch desperately in my irons, I have real struggle in getting height and spin out of shots even though I am a pretty consistent ball striker. I often find my irons rolling well out even with short irons. It is something I am working on and have Nippon 950Gh’s in my irons, but this looks like it will be a nice forgiving but not stupid ugly super game improvement set.

Finally… A set that resembles a better player like combo but for guys needing game improvement. Jumping on these once they come out.

If you’ve been looking for a “better player like combo …with GI”, the Mizuno MP-H4 (and now H5) irons have been out for years. Not only do they (arguably) look better than these, I would bet a sizable amount of money that they feel better than the Cobra’s too.

I plan to hold out to try the Cobra’s as I suspect they will be a fair bit more forgiving than the MP-H line, which are arguably borderline better player’s irons.

being 2 hdp and having had mph4 and mph5 and fly z i can tell you the fly z was way way way more forgiving across the entire face with zero hot zone…..basically everything went the same distance….normally on game imp clubs you get hot shots….callaway is prone to this for sure…..i found the 3-8 iron to have a great profile little offset with the 9-pw a bit big bulky. performance and feel was great….i sold my set for srixon 745 and that feel is amazing and performance is fine…..i do miss the distance consistency of the cobra fly z though….i am interested in the f6 set mainly due to its more progressive…..although id probably dislike the extra offset in the 3-5……..

I might buy these brand new, which is something I very rarely do. Beautiful and smart…wow!
