The Flat Cat putter grips are a unique entry into the marketplace of large putter grips.  Worth a look for anyone struggling with their putting.


Golf Channel viewers are no stranger to seeing Hank Haney in commercials, and the latest product that he’s put his name behind is the Flat Cat putter grip.  Designed to square your hands to your target, Flat Cat is guaranteed to improve your putting performance.  We tested them to see if they’re worth a try.

The size alone would make the Flat Cat stand out on the course, but this newcomer also brings a bold look.  The combination of white and neon green looks sharp to me, but it may not be for everyone, particularly those who don’t want to field a dozen variations of, “What is that grip?”  My favorite touch is the black and green eye on the butt of the grip.

All sizes of the Flat Cat putter grip feel similar to a Super Stroke grip.  It feels as if there’s a wrap of soft material over a light foam core.  This does tend to dull the feedback in your hands a bit, effectively making your putter feel a bit softer at impact.  Whether or not that’s a good thing is up to you and the putter you currently play.

As you can see, the Flat Cat comes in four sizes, ranging from slightly larger than a normal grip to absolutely huge.  For what it’s worth, I have reasonably big hands, and I found the standard size grip very comfortable.  As you can see below, the total size of the standard is similar to the SuperStroke 2.0.

The first time I had the Flat Grip grip in my hand, it spurred something familiar that I couldn’t put my finger on.  After some Googling, I figured out that it was reminding me of the 2Thumb grip from a few years back.  The key difference (beside the weight) is the way the grip is meant to be installed – the 2Thumb wanted the wide surface perpendicular to the putter face, the Flat Cat wants it parallel.  In this orientation, you get your right palm and the back of your left hand to mirror the putter face which, in theory, makes putting more natural and intuitive.

I installed the standard sized Flat Cat on an Anser 2 style putter and headed to the course.  As I said earlier, the size of this grip is similar to my normal SuperStroke 2.0, so, despite the different shape, the transition wasn’t difficult.  Also, the weight is similar to my normal grip, so I didn’t have to battle with a change in feel.  Of course, depending on the grip you currently play and the size of Flat Cat you try, this may or may not be true for you.  The weight of the Flat Cat grips varies substantially, from 44 grams in the Slim to 103 grams in the Big Boy.

Overall, I did putt pretty well with the Flat Cat grip, and I found it very comfortable for my left-hand dominant putting style.  The large size and rectangular shape made it easy for me to keep a firm grip in the left hand while keeping the right hand loose and largely uninvolved.  Flat Cat states that their grip works with any style of putting – left hand low, saw, claw, etc – but I would be curious to know how players who have different sources of motion respond to it.

Though the Flat Cat grips aren’t exactly cheap – $28, regardless of size – they do come with a 30 day, money back guarantee.  So if you’re struggling with your putting or just looking for a little spark on the greens, the Flat Cat putter grips are worth a look.

  1. Interesting, no hole in the back of the grip though? I like to try these large size grips with airgun and masking tape first. Even with solvent, it doesn’t come out from the back side?

    • Matt Saternus


      I installed mine with solvent, and it felt like a bit did leak out the back. My guess (though I don’t know, haven’t taken one apart) is that the eye covers up a hole or minimally isn’t affixed in an airtight way.



  2. What an awesome grip, really keeps my hands square all the way thru the put.

  3. There is a hole in the back (or top) of the grip. It’s offset on the side. Just installed one with ease on my putter.

  4. could you give the specific sizes of the grips kind of hard to determine the circumference by pictures alone, I cant find any in golf stores, some places don’t know what I am talking about???

    • Matt Saternus


      I don’t have the grips anymore, so I couldn’t give you the measurements. I would suggest contacting Flat Cat or checking their website.



  5. Hello, what’s the difference between the flat cat grips with the “white” cone ($24.99) and the flat cat grip with the “silver” cone ($49.99) ? Thank you

    • Matt Saternus


      I’m not sure, I don’t recall there being different “cones” in the allotment that I tested.

    The silver cone (solution) has a weight at the bottom to counterbalance your putter. The white cone is just a standard grip.

  7. I really got here more valuable resoucres. just great and more thanks fo this good share

  8. Another gimmick! Flat front hand, usually your last 3 fingers, with a set or firm lead hand, take back hand back, and take toward target! Anyone thinking of getting a Flat cat, I suggest practice! there are hundreds of video’s on putting on YouTube! You can’t buy a putting stroke!

    • Chuck….. but if you have a putting stroke you might find this makes it just a little better. You might make one more putt per round! You might make that extra birdie to make the cut! Chuck you might just be a little negative with a touch of arrogance!

  9. Darren, I too feel that Chuck has quite a bit of arrogance and I’m sure he does things on the course as others wouldn’t but it works for him. Shouldn’t criticize something that works for others.
