Tatara Razors Muramasa Adjustable Closed Comb Machined DE Safety Razor, Matte Finish

We currently have 7 in stock.

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.


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.


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


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.


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.


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.


⚫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.


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.


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.


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.
