Earlier this year, we introduced you to Astral Putters, a company that is approaching putter design like nobody else. If you haven’t read our brand story on Astral, we highly encourage you to do so before going any further. The company’s journey from dream to reality is a compelling example of the power of the entrepreneurial spirit. Today, we dive into Astral Putters themselves. From the components to the fitting approach, we’ll cover it all.
The Astral Story
We aren’t going to rehash Astral’s entire brand story here since we covered it so thoroughly in the article linked above. However, if you’ve already read that it’s worth a quick summary.

Astral’s founder, Blake Callaway, was formerly an attorney with a passion for putter refinishing. Through all his experience working with putters and experimenting on the putting green he came to realize that fitting options available from mass-market equipment manufacturers were not meeting his needs. While he was able to go to the golf store and try dozens of different options, most of these options fit inside a very narrow window and didn’t offer the customization needed for him to maximize his performance.
Blake came to believe that toe hang and shaft offset were the two primary factors in delivering a repeatable square face at impact. However, the particular combination of those two factors that worked best for him, slight toe-hang and minimal offset, was almost impossible to find.
Thus, the idea behind Astral Putters was born; highly customizable putters built from components and a fitting system that allows each person to precisely dial in a putter to their individual stroke. Through consultation with the company’s experts, consumers can put together a putter that not only matches their needs but can be adjusted in the future if anything changes.
The Heads – Astral Putters
We’ll dive into Astra’s fitting system in a moment, but we have to start with the part that most of us look at before anything else – the putter head. Astral offers three different choices, and each one can be dialed in. In other words, consumers can pick the head they desire without any strings attached. Yes, since they are shaped differently, they will offer varying levels of stability and MOI, but the moment of truth (impact) will be the same.

The Blade is the most traditional of the three Astral offerings. This slim and compact head is a classic for a reason. It’s nimble, responsive, and gives the golfer the most opportunity to control the club head through the stroke. Astral’s blade features a moderate toe-to-heel length, square lines, and rounded bumpers that step down from the top line into the flange.
The Mid-Mallet is better known by golfers as a “double-wide blade”. It’s shorter than the Blade from heel to toe and is deeper from face to tail. This design will provide a bit more MOI (resistance to twisting) and a more modern looking option that should be popular with a wide variety of golfers.
The Mallet is a shape unique to Astral and is our favorite of the three. It’s a take on the fanged mallet we’ve all come to love but has its own unique look to set it apart. In some ways it almost reminds us of Batman, with the edges of the flange diagonally reaching out from the center to the tips of the fangs. As far as mallets go, we consider it to be on the smaller side. It’s relatively compact, but you still get the stability benefits this design typically offers.
The System – Astral Putters

The centerpiece of the Astral fitting system is the hosel. There are three “Z” shaped hosels of different lengths to choose from, and each one produces a different starting point when it comes to how much toe hang is available. The shortest encourages the most toe hang, the longest works best for face-balanced configurations, and the middle length bridges the gap with its versatility.

That’s not all though. These hosels can be oriented in any way the user wants in a 360 degree circle, producing wildly different results. What do we mean? Look close at the end of the hosel in the picture below. See the notches? Each one represents a clock position and there are 10 of them to choose from. Better yet – each hosel is reversible and the other end has another 10 notches to offer 10 more clock positions. Having a hard time imagining this? Let’s look at the picture of the three heads below, each with the hosel in a different place.

The Blade (far left) shows something similar to the type of offset we’d see with a plumber’s neck hosel. The Mid-Mallet in the center shows no offset at all. Finally, the Mallet shows a configuration similar to a flow neck hosel. All three of these settings are fairly common in production putters, but there are some wildly unique choices available. Want to try some onset? How about approximating a Zero Torque putters? You can do it with Astral. Better yet, you use the different hosel lengths to balance your desired amount of toe hang with the offset look you prefer at address. The options are almost limitless.
Fitting
It’s easy to see that there’s a level of complexity to the Astral fitting system. The execution is quite easy though. Each component attaches with a screw that tightly secures it. In fact, you’d be hard pressed to know that these putters are combinations of components when they are fully assembled. The company takes great pride in the tight tolerances they are able to produce.

Where to start though?
First, if you’re not a devout putter nerd that knows exactly what works for you, we highly recommend taking the path of least resistance. Reach out to the company. You can meet with their experts at no additional cost, and they will guide you to the right fit via email and eventually a video conference. They will discuss your aesthetic preferences and common misses in pre-consultation. Once you have their putter in hand, they’ll watch you take putts and guide you through the necessary adjustments to really dial things in.

What fun is that though?
We’re joking of course, but the fact remains that there is a group of us out there that has both the knowledge and desire to tinker, and Astral is the tinkerer’s dream come true. For those of you like us, we still suggest reaching out to the company to talk options, but from there we’ll point you to their fitting page. There you will find a full explanation and diagrams of the Astral system, along with a number of suggested starting points to build common putter configurations.
Throughout the review process we built flow necks, plumber’s necks, face-balanced putters, a zero-torque style design, and some we aren’t even sure have a name yet. The process takes a few minutes at most and is incredibly gratifying, as you can almost instantly see the results from your changes. As adventurous as we were, we still found that the old-fashioned flow neck worked best for us. Old habits are hard to break.

Of course, putter fitting has considerations other than offset and toe-hang. Length and lie angle are vitally important as well. Astral provides guidance on both of these things, and their method of choosing a lie angle was particularly helpful at home. As you likely know, lie angle impacts how upright or flat the putter and the shaft come up from the ground. Most companies default to 70 degrees. Improper lie angle can trick you into standing too far from or too close to the ball. It can force changes in your setup that negatively impact your natural stroke.
In addition, we learned that our desired lie angle could even change with the style of putter we were using! For example, the flow neck design by nature tricks the eyes into wanting to stand further from the ball. By adjusting it more upright with one of the five spuds Astral offers we were able to achieve a comfortable setup with our preferred head shape in seconds. This alone was worth the price of admission – a true “lightbulb” moment.
The Options and Customization
It seems crazy to say that there are even more ways to customize and dial in an Astral Putter, but there are. The company truly wants their product to be something that will last you a lifetime, and they’ve found ways to future-proof their putters.

First, as part of the fitting and building process, there are both shaft and grip options to pick from. The black KBS CT Tour shaft is available in a no-step or single step option. In addition, there are five grips available from Winn and SuperStroke.
Our favorite piece of customization is on the putter head itself. Astral’s component design goes even deeper than fitting choices. It allows you to swap the face insert and radically alter how the putter sounds and feels. Three base options are available: brass, copper, and carbon steel. Each one is much thicker than the inserts we typically seen on production putters and has unique properties that makes it stand out from the others.

Astral describes the brass as “crisp”, which is another way of saying it’s the firmest feeling insert they offer. Make no mistake – you will notice the firmness and high-pitched “ting” sound of the brass insert right away. There is a small group of enthusiasts out there that love the brass feel, and Astral delivers is nicely with this option.
The copper insert is described as the softest of the three, which proved to be true in terms of tactile feedback. This soft metal is undoubtedly much smoother than brass, though it does still carry with it a slightly higher pitched sound at impact. One thing we loved about the copper insert was its smooth, uniform look when installed. It contrasted nicely with the black head and provided a great visual cue for alignment purposes.
Our favorite of the three stock Astral insert options was the carbon steel. This insert is decidedly the most “modern” of the three in the sense that it is very familiar sounding compared to other current milled putters. Impact produces a soft, low-pitched click that we enjoyed with a variety of golf balls.

Are three insert choices not enough for you? If not, Astral even releases limited edition face inserts throughout the year. We had the pleasure of trying a Damascus steel insert, and it was impossible not to fall in love. The softness, responsiveness, and amazing visuals from the Damascus steel made this a winner in every sense of the word.
Astral offers a full customization program with engraving and color finishes in almost any combination you can imagine. They also utilize their custom program to create limited edition putters throughout the year. A personal favorite of ours was released ahead of the Masters last month. Emblazoned in green and yellow, this Reserve Series Augusta Collection putters from Astral are true standouts.
The Performance – Astral Putters Review
Finally, we come to performance. This was a tricky category to judge Astral putters in – not because they didn’t perform, but because they can (and do) perform so differently with every change that is made.
We felt like it was our duty to build and test as many configurations as possible in the last couple months. First, it was fun, but we also wanted to know if these builds behaved like we expected them to.

So, we had great putting performances, and we had some days better off forgotten. Why? Simply stated, because fitting matters. For example, the flow neck with an upright setting we built produced amazing and repeatable success. A face balanced putter we built did what face balanced putters do. Unfortunately for us, face balanced putters don’t make many putts. The plumber’s neck build delivered ample toe hang and face closure through the stroke. You get the point, which really proves Atral’s entire point – if you take the time to really dive in, whether on your own or with their experts’ help, you can craft a putter that wants to deliver a square face over and over again.
The Details – Astral Putters Review

Base prices for all Astral Putters start at $500. That price can increase if you decide to order extra fitting components like hosels, lie angle adapters, or face inserts. Custom options and Reserve Series putters are obviously priced a bit higher to reflect the additional work put into the product.
We highly encourage you to visit Astral’s social media pages and website, astralputters.com. At the least, you might start to learn just what it is that makes a putter work for you. You might even come away designing your own.
This is a superbly written review [USER=1193]@Hawk[/USER]. From following along with the brand story and some of the options shown there, to the amount of detail and breakdown present here, it’s very hard to not want to try one of these out. The spuds to go upright are very intriguing and something I had missed up until now. It feels like there nearly nothing Astral hasn’t thought of and then done even more by presenting customization as well. Very very cool.
Have to admit after messing around with these it was pretty darn cool all the things you can change. The different feels on the different faces was wild. Thanks [USER=1193]@Hawk[/USER]
Great writeup [USER=1193]@Hawk[/USER] ! It’s been fun to follow the journey that has been Astral putters. From the initial views that gave us a great look at all the options, to the fitting process. Then onto the tinkering, which was really fascinating, just a great view of what can be achieved.
The company and what they are doing is unique. I think it’s really cool what they are doing offering so many combinations. The custom options and changeable face inserts is really cool. All this while maintaining high standard of build quality.
I think the Double Wide with the Carbon Steel or Damascus insert would be an awesome combination, but I’ll be honest that mallet has grown on me a bit.
Really good article and I think I want to spend some more time with one of these. I love to tinker with things and this is the ultimate way to do that
Great article and really cool product
Great article, and really cool looking Putters. Love the seemingly endless options for tinkering, but like [USER=1193]@Hawk[/USER] said I would probably end up getting myself in trouble tinkering too much without it being a proper setup for me.
I don’t need one.
But looks fun as heck to play around with. 🙂
That’s a great read, [USER=1193]@Hawk[/USER]
I have to admit, they surprised me in person and in hand when you brought them to the staff retreat.
There’s a LOT going on, but the attention to detail when it comes to machining and how each part fits is absolutely stellar, especially given the price.
[USER=1193]@Hawk[/USER] – great job in laying out the various array of options. The details in the photos with how you can play with the part was like a big tease. You have to love how he found a gap in the market and combined it with his love of putter finishing to create something special. It seems like even though you have a good sense of what is right for you there was still value in getting that last little bit dialed in.

To be honest, I just tinkered because I felt like it was my duty to do so. If that wasn’t the case, I would have built that upright flow neck and probably never changed a thing.
Really well written [USER=1193]@Hawk[/USER] quite the tinkerers dream in a set up that gives almost endless options
wow that’s a lot of info on a putter 😮 never really thought of it being that different & detailed, but clearly it is. That’s really getting dialed in for sure. Great write up [USER=1193]@Hawk[/USER] (y)
Astral is one of my favorite companies that i’ve been introduced to through THP, it’s an incredibly unique piece of equipment as the review lays out. Tons of customization and it’s very easy to do. Also Blake will do a fitting with you which is really fun.
Once you’ve settled, you can make it look pretty darn traditional if you want. It doesn’t HAVE to be wacky though it can be.
The appeal to me was a brass face (which i love given my history with another vendor) in a double wide head. I play mine in a very traditional look.
Afternoon bump!

I messed with all of them at the retreat.
For me it would be mid-mallet with it set up in a no offset orientation with the copper insert.

[/QUOTE]
They’re two very different audible feedbacks. So a decent amount.
The way the inserts are designed, the steel will come off more traditional, while the copper is a bit higher pitched and different from the trends.

If you want to mess around with lefty you can try the brass this weekend too
It’s a bit more of a “hollow” brassy feel than my Deschamps. Pretty nice outdoors so far.
On very sunny days, I’m interested to monitor the glare, though blake did say this might be something to consider on very sunny days. The brass is a bit shiny

Had you been for upright before? Or was this a first as you went through there process? The whole height/stance matrix thing is pretty neat and makes that accessible to folks not close to a more tech-forward putter fitting experience

[/QUOTE]
I’ve never used a putter that was anything other than stock when it comes to lie angle or loft.
Generally speaking, I like to be a bit more over the ball with a putter. Not extreme, but I have a definite preference. I try to maintain a relatively upright posture.
With certain putters, I can set up the way I like and the head sits flat. With some others it seems like the heel wants to sit off the ground a bit, so I have to either manipulate my hands/arms or move farther away from the ball. That’s what was happening when I first built the Astral Flow Neck. I felt like I was a mile from the golf ball, so I immediately used the matrix. It suggested moving upright, so I did and the whole thing just came together.
What was so interesting to me was that other hosel configurations weren’t giving me that same “mile from the ball” feeling. I emailed Astral about this right away, because this thought was forming in my head that all lie angles weren’t created equal. The eyes create an illusion of sorts that change how we perceive the lie angle with certain hosel settings. The confirmed that I wasn’t crazy and noted that my experience was quite common.
After tinkering with going upright, or adding offset/onset, etc. do you know what the measurements are as far as lie angle? I’m assuming loft, or at least static loft, doesn’t change?

As far as I know the loft didn’t change.
I went to 74 degrees with the flow neck. It sounds extreme for sure, but feels very natural to me.
I mentioned if you want to keep it looking really classy, you can do that.
Mine is set up pretty standard

Yes, will have to check it out for sure.
Wanted to come back to this. I got to test the putter at VN on some tough greens. And the Tuesday we got fantastic weather and dry greens
I will say the brass is a bit “pingier” than my Deschamps brass putters which you do feel a bit. I don’t know how to describe it but the contact feels a bit “lighter” . I am guessing because the insert is a bit thinner that my other brass putter which is fully milled.
That being said, I loved the performance. For my 5th and 6th rounds I was very comfortable. It sets up very nice, and I made confident strokes. I like the weight and it felt good outdoors, I could feel the head well throughout the putt. It’s a soft brass and will likely take a few cosmetic dings just FYI but that doesn’t bother me
In the 2 18 role rounds I think I rolled in 7 birdie putts IIRC and all of them were 6-7 feet or more. For early in the year this was really good putting for me

They are REALLY fun if you are a tinkerer. I was talking to JB about them also. Some of the looks you can do are really wacky and unique . I don’t know the amount of unique looks but it’s gotta be 100s
I play mine pretty standard but even then it’s cool knowing I can just buy a different insert and get a new feel
And I like they are a heavier putter if you’re into that. It’s like a customizable square back. For me this was super appealing
