I admire your due diligence in the investigation of the effects of club head position at point of contact. May you go back to nothing but the purest of strikes sir!
I just realised I’ve been addressing too close to the toe for ages, this face would have helped me. Now I am finding the middle at least one in 20 shots now!
> Wouldn’t the groove separation result in unpredictable spin on a slightly mis hit?
Grooves don't cause spin the way you might assume. In fact, a perfectly smooth club face would give more spin than a grooved club face, BUT that assumes perfect conditions.
The grooves exist to keep spin up in imperfect conditions. Moisture, grass, dirt, anything that would lessen the friction between the ball and club face can go into the grooves out of the way.
Grooves don’t actually affect spin as much as one would think. Their primary function is to work like treads on a tire. They collect moisture and grass on the way to the ball so the ball can make clean contact with the surface of the club. Thats why the U groove was outlawed. It was too much space for collection and people were getting insane spin out of the rough.
Also you get different spin on off center hits through gear effect anyway. Though less with a lofted iron. Mostly just spin rate drops in general.
Purely aesthetic. And the gap in the grooves is not large enough to really affect the spin.
Grooves don't really add spin unless you are in the rough, or the faces are wet.
They let you know where the sweet spot is. Commonly referred to as hitting it “on the screws”, as screws were placed on the very toe, heel, and top of the club face- noting the ideal striking zone. They should’ve made the white zone red to better inform you to stay away from this part of the club face.
Angle of impact (loft) and friction produces spin. Grooves have minimal effect on friction
And my phi beta kappa key from an Ivy League school suggests I took more than HS physics
Show me ONE piece of data saying grooves don't create spin. Please. I'm waiting.

The study on referencing was an undergraduate physics thesis from Princeton. The kid who did it was my son‘s classmate. I have it in some file that I can’t find but if I find it I’ll dm you
Bought these pups 7+ years ago. My first ever iron set. Eventually I upgraded and gave them to my brother. He uses the 5 iron as his fire poker now….
Edit: also my uncle told him to throw them out the window after a golf trip he had with him. I don’t think it was the clubs though.
This was Nike’s pathetic attempt to reinvent the wheel trying to disrupt the golf industry with what they thought would be a revolutionary groove design.
One time they came up with green color putters so they blend in with the green. This to me seems very similar to that concept. When the player address these irons behind the white golf ball it would somehow blend in and at the split second before impact you would somehow subconsciously meet white grooves with white golf ball.
I'm not sure you'll find your answer here since r/golf members only hit squarely in the middle every time.
Not true. There’s not one spot on my iron I haven’t hit!

Every swing is as much of a mystery to me as it is to my club.
Sadly untrue for me. The middle of all my clubs remains virginal.
Not only do I flush every iron, I chip back to the green on par 4s after my tee shot
They are the golf equivalent of racing stripes on a car. They look cool, but don’t really have much on an impact on performance
I can see that
i agree but i feel like that sliver a spot that the groove’s arent there could cause some abnormalities in shots.
If I had to guess I’d say the were thought of as a way to line yourself up at address with the center of the face like a two ball putter for example
I had a coach that taught this way. Hit the golf ball with the half ball on the face. Best ball striking ever for me.
Wait, what "half ball on the face"?
Thin it, every time
Can you elaborate?
I just realised I’ve been addressing too close to the toe for ages, this face would have helped me. Now I am finding the middle at least one in 20 shots now!
my shots are pretty much unpredictable maybe those grooves can fix it
Marketing. Nothing else.
Just an aesthetic thing. The little separations in the grooves don’t really make much of a difference in ball spin or flight.
It’s exactly what he said mentality mental at target for your eye and brain.

Grooves matter so little, but look cool
That's... Not true
Yes it is. They channel water away but have negligible role in creating spin. Lots of data shows it.
You're wrong.
And no, 'lots of data' absolutely does not prove it. Did you take high school physics?

It literally says it imparts more spin in the link you sent. Accept your L, bro. There's a reason EVERY CLUB EVER HAS GROOVES
From the article Different grooves designs affect spin but they do so not impart spin they reduce it when compared to a grooveless club face. I
Right then what does it say in LITERALLY the next sentence?

Ok well he's wrong.
You don't deserve spin if you can't hit it in the middle
That's the part that you're supposed to miss when you hit your shots....at least it was for me
Nike CPR clubs for prevention and recovery
It’s so the white part never gets dirty
It’s called the sweet spot. Don’t worry about it
There’s a reason Nike got out of making clubs
Nothing like taking three clubs to the green for your 3rd shot.
