Miyabi Koh 8 Chef’s Knife Review (Miyabi 4000fc Review)

Where it’s made

Miyabi knives are manufactured in Japan. Though Miyabi is owned by world-renowned German cutlery manufacturer Zwilling, all of the miaybi knives are handcrafted in Seki, Japan. Highly trained knife craftsmen make those knives using traditional Japanese knife-making and sharpening processes. Those represent some of the highest quality. Garman Engineering meets with Japanese years old craftsmanship in this Miyabi koh 8 chef’s knife.

Blade material

The most important part of a knife is its blade. And the quality, durability of the blade depend on the material it is made with.

The blade of Miyabi koh chef’s knife is made with revolutionary FC61 fine carbide stainless steel. It’s high-quality steel with tough hardness. It contains different types of components like carbon, chromium, cobalt, etc. Carbon components increase the hardness of the steel and ensure long-edge retention. Chromium makes the knife rust-resistant. Finally, cobalt also contributes to the strength of the blade. 

These components make the blade strong, and hard with a razor-sharp edge. 

Blade Design

This blade has a traditional Japanese profile with a sandblasted katana edge. It features a mirror polish with a beautiful look. 

This blade has a slight curve from both the top and bottom parts. This design makes the Miyabi koh chef knife perfect for both Western chopping and Asian rocking cuts.

This blade is a dual bevel knife, unlike a traditional Japanese knife. It means this knife has the same edge angle sharpness from both sides. This makes its design usable for both left and right-handed persons. 

And the spine is grounded and smooth so it provides quite a comfortable pinch grip also. Finally, the embossed Miyabi logo gives the whole knife an elegant look.

Sharpness and edge

Miyabi koh chef knife has an authentic and hand-hunted 9.-12-degree cutting edge. That’s a two-time sharpener than usual chef knives. You can use this knife for every type of chopping, cutting, slicing, or mincing task. 

The scalpel-like sharpness of our knives is attributed to the revered Japanese Honbazuke process. This time-honored method comprises three meticulous steps. In the initial two stages, the knife edge undergoes precision sharpening with both vertical and horizontal blades. The final touch involves a mirror polish achieved on leather. Rooted in tradition, this sharpening process, employed for centuries in perfecting the sharpness of samurai swords, ensures an unparalleled cutting edge.

Handle material

The handle is made from pakkawood . Pakka wood is not raw wood, it’s a composite of raisin and wood. 

Pakkawood doesn’t absorb water or moisture, so the handle doesn’t slip from the grip and ensures a comfortable grip. Bacteria don’t harbor this. So, it ensures the long-lasting, durability, and resistance of the handle. Moreover, pakkawood also made the handle very beautiful

Handle Design

Miyabi koh 4000fc  features an octagonal-shaped handle. This ergonomic handle feels as good as it looks. It fits properly in the grip of the hand. Both left and right-handed people can use it comfortably. The pakkawood handle supports both Asia rocking cuts and Western chopping.

There is a beautiful mosaic pin at the center of the handle. It makes the handle more durable by adding more beauty. 


The blade goes through the whole length of the handle, which means Miyabi koh chef’s knife is a full tang knife. A full-tang knife is always preferred over a half-tank knife. Because generally, full-tang knives are more durable than half-tang. This full tang contributes to the balance and weight distribution of a knife. 


Miyabi Koh knife has a Rockwell hardness of 61 which points to extreme hardness. With the increasing of hardness the edge retention and durability of a knife increase. 

Miyabi employs an advanced ice-hardening technique to enhance the hardness of their knives. Through this meticulous process, the blade undergoes controlled heating in a vacuum-sealed oven, followed by rapid cooling to normal temperature and then further reduced to extreme freezing. This cyclical cooling and heating method intricately refines the inner structure of the steel. Consequently, the FRIODURx2 blade of the Miyabi 4000fc gyutoh achieves exceptional durability, delivers an unparalleled cutting experience, and maintains razor-sharp sharpness. 


Miyabi koh knife has an 8 inches long blade. The total length of the knife is 14.75 inches. So the handle length is more than 6.5 inches. It is perfect for both small and large-hand users. 

When it comes to the thickness. This knife is very thin and lightweight. It has a thickness of only one inch. This site is all-around perfect for a variety of works.

This knife has another version for those who love more large blades. That version has a 9.5-inch blade. Inthat handle length also vary and you may pay a little extra. 

Weight and Balance

Balance of the knife while working is one of the most important things. Otherwise, how beautiful the knife it doesn’t matter. For proper balance, the weight distribution of a knife should be perfect.

Clean and maintenance 

Like all Miyabi knives and Japanese knives, the Miyabi Koh 8 chef’s knife prefers hand washing only. It is not properly dishwasher safe. Washing it in the dishwasher may cause chips or damage.

So, after washing, put the knife in an open place until it dries out properly.

Miyabi Koh 8-inch chef’s knife doesn’t come with any sheath. So, you need to use an extra sheath or any wooden knife block to keep the edge safe. A sheath or wooden block must cover the whole blade portion otherwise it may be unsafe. Try not to use a magnetic knife holder that may cause the inner structure of the knife.

A knife may be beautiful or made with quality material but the only thing that matters more is how the knife feels in hand.

With an octagonal handle shape, this knife will be comfortable for both left and right-hand use. The handle material gives a very comfortable grip and doesn’t slip from the hand. As it doesn’t absorb water it will not feel wet or slippery.
