Research by the brand showed players testing the King One Length irons improved in accuracy, with tighter distance and dispersion variation from shot-to-shot, leading to increased confidence and better iron play.
The King F7 and King F7 One Length irons incorporate progressive cavity construction to optimise the performance characteristics of each iron.
The King Forged One – as used by DeChambeau – have tungsten weighting in irons 4-7 for lower and centered CG while a TPU insert in irons 4-8 dampens vibrations for better feel and moves weight toward the perimeter for added heel and toe forgiveness.

Cobra admit they are unsure to what extent club golfers will buy into the concept but they’ve certainly done their homework on the performance benefits.
Cobra King F7, Forged Tour and One Length irons – Results/NCG verdict
After hitting shots with the King F7, Forged Tour and King Oversized irons it’s clear once again that Cobra have upped their game in this area.
Sound and feel with all three are very pleasing, there are very good shaft and grip options. Whichever package suits you, you won’t get short-changed.
The King OS irons are incredibly easy to launch and will fill players with plenty of confidence. There’s even an alignment aid on the face.

For me (17 handicap), they were just launching a bit too high and spinning too much but for someone who struggles to get much air time these could be a revelation. They did have a very light shaft too. They all went dead straight for me too.
I immediately noticed a bit more carry with the Cobra King F7 irons as the spec was much more suited to me. Dispersion was also nice and tight.
The performance of the Forged Tour was arguably the best for me out of the three which I didn’t expect but I know the Cobra King F7 will perform better for me on mis-hits.
I absolutely love the look, sound and feel of the Forged Tour. They would be a incentive for me to get better because of the feeling you get when hitting one out of the middle.
What’s absolutely clear is that there’s a Cobra iron for every type of player in 2017.
Stay tuned for a more in-depth review of the One Length irons which we felt needed to be tested over a longer period of time to get tangible results.
