Muramasa Adjustable Razor

The Muramasa is a highly efficient and comfortable adjustable safety razor that allows shavers to choose the preferred shave setting (smooth or aggressive) by simply turning the razor dial.


Due to its fine-tuning adjustable mechanism and superior construction quality, it provides an adaptable shave. Perfect for both wet shaving beginners and experts.


The Muramasa adapts to your skin and hair but it’s also perfect for a rushed shave if you need a more forgiving setting, or if your mood simply demands something new.


Weight: 105 gr / Dim. 88,2x44x25 mm / Handle: Ø11.7×59,6 mm

Muramasa Base Stand
After trying the Masamune and being overwhelmed by every aspect of it I was curious to try the Tatara Nodachi (OC & CC) as well, so I recently bought that one too … well, the Nodachi even won over the first place in my favourite list over from the Masamune hands down. Build & finish quality is literally top of the line, absolutely marvellous and it comes with the same lovely design as it’s cousin. The Nodachi gave me an absolutely amazing BBS shave with the first run, very smooth (even with the Feather blade I preferably use) and super efficient. It’s blade exposure is a little more to my taste than the Masamune’s (but your mileage may vary) and the longer handle gives me even better control when shaving what’s left of my head hair. As a European I am very happy that I can buy such a great product - imho the best razor I own so far - within the EU. I would like to add that the service offered by the team at Tatara is also great - there was a little problem with my order and delivery which was solved immediately and with very good communication by João :)
Where to start? Firstly I was pleasantly surprised at how quickly it arrived from Portugal. Then, opening the package I was very impressed when I saw the box neatly wrapped in black tissue with a wax seal. It looked so classy - like a Christmas present - it almost seemed a shame to open it! However, with utmost care, that is exactly what I did; then to discover the Masamune beautifully presented in a cork display base. So far, so good. But what of the razor itself? Well, the next observations you will, of course, already know, having created and manufactured the razor. The fit and finish is up there with the best, and the half-moon matching stand has such a close tolerance that there is barely any free movement, holding the razor perfectly vertical. The appearance of the razor is quite different from any other razor in my collection, but it is quite aesthetically pleasing. The rounded bottom end of the handle means it is very comfortable in the palm of the hand; and the handle length is good. Taking the razor apart, I find the length of the thread on the head just right. I have read other reviews where the writer has thought the thread could be shorter. I have 3-piece razors with a shorter thread and have wished they were a tad longer. Personally, I find the length on the Masamune that much easier to get hold of, and I am grateful for it. The Masamune comes with 3 Feather blades. I have to say that, from experience, I am not a great fan of Feathers. Firstly, they are extremely sharp and if used by the inexperienced in the 'wrong' razor can be a tiger; and if one's technique still needs to be honed cuts and weepers are almost inevitable. Secondly, I have found that after a couple of 3-pass shaves the blade's performance drops off rapidly. However, in for a penny... In the Masamune these Feathers are an absolute pussycat! Smooth, efficient and nary a cut at all. I was impressed! That said, I still managed only 3 shaves before efficiency fell off and I changed blades. Thankfully, having tried several different blades, such as Wilkinson Sword, Personna Platinum and some other wet-shavers' favourites, which it may be more prudent not to mention in the current political climate & world situation, I found these others proved just as efficient. Overall, then, IMHO the Masamune is an extremely well-built razor; is comfortable to hold, with a good grip; and efficient. For the most part I have used the closed comb bottom plate, and my comments refer to that in particular. I did also purchase the open comb plate, but on the odd occasion I have used it I haven't found it as comfortable or easy to get on with - probably need more practice. But, for now, the Masamune head and closed comb plate combination provide a mild yet efficient shave, which is just what I want as a daily shaver. Needless to say this razor has found itself a permanent place in my rotation of favourite razors. I have observed on platforms such as Youtube that some reviewers don't like certain aspects of the razor's construction, e.g. the handle and the way it locates into the top plate. All I can say - again IMHO - if treated with care this razor could/should last a lifetime. Its design is such that everything fits and locks together beautifully. And, if the worst comes to the worst and accidents happen, it is reassuring to know that each individual component is available to purchase separately rather than having to buy a complete new razor. And there aren't many artisan manufacturers around offering that kind of facility! So, bottom line, if you are looking for a mild, efficient razor that is beautifully crafted and engineered the Tatara Masamune is more than worthy of your attention. Keep up the good work, gentlemen! Best regards - and thank you for a brilliant razor!

I first bought the Masamue OC, design wise, materials and looking at the finish, the razor was perfect. But it didn't work for me and my stubble of hard steel barbed wire. I can immagine a perfect razor for men with litle facial hair. So, I was disappointed. After some hesitation I decided to buy the Nodachi OC. In one word; wow!!!!!!. Loaded with an astra sp blade it gave me the smoothest shave I have ever experienced. Very effective, standard three passes and baby smooth all over without the slightest irritation. I'm a collector, I've more then 100 safety razors from vintage to modern, from the bottom priced to the very high-end brands. But the Nodachi OC beats them all. What a joy to shave with and what a result. I recommend this razor for all man who have a strong beard growth even with sensitive skin, as a daily driver. This razor is worth every penny and that's an understatement. Frank
I just got the Nodachi, an elegant, well-designed razor with heft (it is like holding a really solid chess piece). It is extremely efficient, especially with a Feather blade--newbies be careful! And the customer service is great: JB answered my emails immediately.
I purchased the Tatara Masamune (OC & CC) some weeks ago and am really happy with it ever since. It gave me very smooth yet efficient shaves; the machining and finish are spectacular and the design is outstanding. In fact it makes me happy whenever I take it out of it’s (also very beautiful) packaging to give it a run. It oozes quality and the dedication put into it’s production by the guys at Tatara. I own quite a few premium razors and this one quickly became my favourite …

For Every Skin & Hair Type

After several prototypes, we achieved the perfect balance between every level setting.

The very mild configuration at level 1 is ideal for more sensitive skin or shorter facial hair. Perfect to transition away from cartridge razors or if you prefer a milder shave.

For more experienced shavers, or when dealing with bigger and curlier facial hair, our top setting has a greater gap and higher blade exposure for a closer shave. If you wish to fine-tune between levels, that’s also possible.

Patented Adjustable Sliding Base-Plates System

The Muramasa’s unique blade exposure setting, made possible through the sliding base-plates system, provides:

⚫ Simultaneous adjustment of blade gap and blade exposure

⚪ Wide-range of adjustment ( 5 levels, pre-set levels with in-between adjustability)

⚫ No need for “wear and tear” pieces like springs

⚪ Quick adjustment without disassembling the razor

How It Works

The Muramasa razor is comprised of an adjustable sliding base-plates system that provides a strong support to the blade and a quick adjustment of the blade exposure (BE) and blade gap (BG).

While rotating the dial you will move the base plates together/apart from the razor’s head, changing the point of contact between the blade and the user’s skin.

This means a difference in BG and BE at the same time.

A numbered window will display the level setting you are at as you rotate the dial.

Superior Manufacturing
316L Stainless Steel

To ensure maximum performance and longevity, all the pieces are made from solid material and CNC machined in AISI 316L marine grade Stainless Steel.

Our expertise with CNC machines allows us to reach unbelievable levels of precision, with tolerances as fine as 0,02mm. This guarantees minimal friction and wear to all the parts, providing durability and contributing to the safe use of the Muramasa.

No Bulky Heads

Thanks to our simple and efficient patent-pending mechanism, we managed to keep the head dimension to a minimum.

The result is a beautiful razor that can reach anywhere on your face, even the more complicated areas around the nose and mouth.

To improve user safety, we also covered the blade tabs to avoid cuts during the shave and while changing the blade.

Choose Your
Favourite Setting

⚫1 - gap = 0.60mm / exposure = negative 0.17mm

⚪2 - gap = 0.70mm / exposure = negative 0.07mm

⚫3 - gap = 0.75mm / exposure = 0 mm

⚪4 - gap = 0.80mm / exposure = positive 0.07mm

⚫5 - gap = 0.90mm / exposure = positive 0.17mm


The design of the Muramasa was thought as a unified entity and not as a raw mechanical assembly of different parts.

The handle is designed using a twisted dimple pattern that enlarges towards the head of the razor for a better grip while displaying the concept of an adjustable razor.

The compact design was developed to avoid blade chatter and blade rattle to ensure a safe and efficient performance in every setting.

Blade Chatter Free

The wide contact area that supports the blade between the cap and base plate is one of the most important features of our razors.

It guarantees that the blade does not vibrate during the shave, giving the smoothest shave possible, ultimately avoiding blade chatter and blade rattle known to cause nicks and cuts.

Every Piece Is Hand Finished

All the 7 pieces in the Muramasa are hand finished and sandblasted - piece by piece.

Through this process, we achieve a smoother gunmetal matte look, softened edges, and we eliminate CNC machining markings.

The numbered piece on the Muramasa dial is inspired by the analog watch date window and is coated with dark PVD to allow a better glance at the number setting.

Elegant & Sustainable Packaging

Your razor will be proudly and beautifully packed in a natural cork box, covered by a textured linen cardboard box marked with our golden logo and sealed with a magnet.

Cork is the bark of the cork oak, which means that it is 100% natural plant tissue and is the only wood that you can obtain without cutting down the tree.

It is a one-of-a-kind raw material from the Alentejo region, in Portugal.

The Key

The way we built the Muramasa allows for an easy maintenance. A rinse after use is enough for your cleaning needs. No nooks and crannies, no hinges, no clutter.

Occasionally, you can disassemble your razor for a thorough cleaning using our included proprietary key.*

Proper maintenance ensures an efficient and safe experience for many generations of wet shavers.

*Replacement keys are available should you misplace or damage yours.
