Make the knife you reach for first a small one.
When you reflect, you always find yourself reaching for the same knife.
For morning fruits, bento boxes, or small preparations.
In the daily kitchen, there are more occasions to quickly cut what's needed than to cut large ingredients.
corebacca is a minimalist knife that condenses the ease of use of a Santoku knife into a 9.5cm blade.
Because it's small, you can quickly pick it up.
Yet, it can cut meat, fish, and vegetables well.
Our goal was to create the knife you reach for first in your daily cooking.
Because it's small, cooking becomes lighter.


The ease of use of a Santoku knife, condensed into a 9.5cm blade.
corebacca is not merely a shorter version of a typical small knife.
It is designed not only for peeling fruit and detailed tasks, but also for chopping ingredients on a cutting board and cutting meat and vegetables.
1. High-grip structure that supports push-cutting
Even with a short blade, the relationship between the handle and blade is designed to easily transmit force to ingredients on the cutting board.
This structure makes it easy to use for mincing onions and chopping vegetables.
2. Handle that prevents slippage
A protrusion at the front of the handle cradles the hand holding it.
This allows even small knives to be held stably and makes it easy to transfer force to ingredients.
3. Small but reliable sharpness
The core material of the blade is Yasuki Hagane's Ginsan Stainless Steel.
It is a stainless steel material that combines sharp切れ味 and rust resistance with daily ease of use, making it suitable for everyday kitchen use.

The joy of choosing is also one of Somaé's charms.
Plain for a gentle impression,
Naguri for a comfortable grip,
Multi-color to add a playful touch to your dining table.
You can choose your favorite wood pattern,
and enjoy it with your cutlery and tools.











Minced onions, or

Shredded cabbage.

Even tough chicken cuts cleanly.
Even tough asparagus spears cut cleanly.
It can also cut a large 1/4 head of napa cabbage.

Use a Santoku for large ingredients.
Use corebacca for daily cooking.
Despite being a small knife, it can handle large ingredients like pumpkins and cabbage.
However, when cutting large ingredients, it's best not to try to cut them all at once. Instead, on a stable cutting board, it's recommended to cut them in several stages as shown in the picture.
Even with corebacca, you can cut smoothly by moving the blade little by little.
Of course, for such large ingredients, a larger Santoku knife is more convenient.
If you own a Santoku, use it for large ingredients.
Use corebacca for everyday cooking.
That kind of distinction is recommended.

General petty knives are small knives specialized in peeling fruits, decorative cutting, and delicate tasks.
However, corebacca excels at more than just that.
It's designed for chopping ingredients on a cutting board,
and for everyday cooking with meat, fish, and vegetables.
The ease of use of a Santoku knife has been condensed into a size that suits modern small-scale cooking.

A minimalist Santoku, the main knife for everyday use.
That is Somaé's concept of a "minimalist knife".

This is not just a small knife. |

3 Reasons to Choose it as Your Daily Knife
|
1. Easy-to-handle size for everyday use |

Including this project and the encore project on Makuake, we received over 38 million yen in support in total.
corebacca, which became the second most funded knife in history, has received many comments from those who have actually used it.
*As of March 2026, based on our own research

Since it arrived, I've literally been using "this one all the time" (lol) Thank you for making such a great product.

It's so easy to use, and ever since it arrived, I've been using "this one all the time," just like the name suggests. It looks cool, and it feels great in my hand. I don't feel any signs of it losing its sharpness, and I plan to use it carefully for a long time.

While it's difficult to cut large items (like pumpkins or cabbage), for everyday use, this one knife is perfectly sufficient. Especially since my hands aren't large, other knives were too big, but this one is a comfortable size and has made cooking more enjoyable.
After actually using it, while it's a bit unwieldy for cutting something as large as a cabbage in half, I felt that it was sufficiently sized for most knife tasks. It's a great product that significantly lightens the effort of knife work, as you can quickly grab it, use it, and then wash and wipe it down.
Supporting your "go-to" knife: the dedicated wooden case.
Tools used daily should not be put away in the back,
but kept in a place where they can be naturally reached.
The corebacca dedicated wooden case is a horizontal type that is easy to store on the kitchen counter or in a drawer.



With a brass plate as an accent,
it was designed to look beautiful even with the knife inserted.
Made of water-resistant laminated reinforced wood,
it's designed to be disassembled and cleaned inside.
Because you can leave the knife out, you can pick it up immediately when you want to use it.
It's not a storage item,
but a case that supports the habit of using corebacca every day.

Not just a purchase, but a commitment to continued use.We'll explain Somaé's reasons for offering free sharpening and our commitment to long-lasting tools. |
From blade to handle to screws.
Made at our own factory in Miki City, Hyogo Prefecture.
Somaé's parent company, Kanzawa Ironworks,
is a cutlery manufacturer established in 1895.
corebacca is manufactured in-house, from blade processing to wooden handles,
and even the brass screws that secure the handles.
Because we manufacture ourselves,
we can provide sharpening, handle replacement, repairs, and parts supply.
We believe that the system for long-term use of small knives
is also part of the product.









Rust resistance and sharp切れ味.
Made with Ginsan stainless steel.

The corebacca blade uses a full three-layer steel structure with Yasuki Hagane's Ginsan stainless steel as the core material.
Ginsan stainless steel is characterized by its sharp切れ味 and high hardness, while also being easy to handle as a stainless steel material.
By combining it with stainless steel for the outer layers,
we achieve a balance between sharpness and rust resistance.
It's easy to use even with acidic ingredients like vinegar and citrus fruits,
making it a material that can be used without hesitation in daily cooking.

Avocado, seed and all, cut in one stroke.
The blade slides through effortlessly.
Even soft sandwiches can be cut cleanly without crushing the edges.

Care Instructions
After use, wash with a neutral detergent,
and store after thoroughly wiping off moisture.
Although it is a stainless steel type of steel,
leaving it wet can cause rust or discoloration.
Dishwashers and dish dryers cannot be used.
To keep the wooden handle clean for a long time,
wash it promptly after use and dry it thoroughly.

For yourself or as a gift.
corebacca is a small santoku knife that is easy to use in the everyday kitchen.
It's perfect for your own home or as a gift for someone special..
A knife they might not have, even if they seem to have everything.
Most homes have large, everyday knives like santoku or gyuto knives.
However, not many people own a small knife like corebacca that can be used for quick daily cooking tasks.
It doesn't overlap much with the knives they already have, and it can add new convenience to their usual kitchen routines.
That's why corebacca is also recommended as a gift for special occasions like housewarmings, weddings, or birthdays.

For breakfast or bento preparation, or for prepping fruits and garnishes.
It's a knife they'll naturally reach for in their daily lives, long after you've given it.
A pleasant experience when giving and when storing.
corebacca is a small knife that can be used casually in the everyday kitchen.
However, precisely because it's a casual tool, we wanted to ensure the impression it makes upon being held is also important.

The packaging has a simple appearance based on light gray.
We made sure the grain of the wooden handle is slightly visible, so you can enjoy the anticipation of meeting the tool even before opening the box.
It's easy to choose for yourself, and also as a gift for someone who loves cooking.
It can be stored neatly when not in use or for safekeeping.
Even if it's a small knife, we hope it will be welcomed as a tool for a long-term relationship.
We've put that sentiment into the corebacca packaging.
If you would like gift wrapping,
please add the gift wrapping cloth bag to your cart along with the product when ordering.
We also offer engraving.
By adding a name or initials, you can make it a one-of-a-kind item.
It also adds a special touch to a gift for someone important.
*The number of characters that can be engraved is up to 11.

Why corebacca is chosen as a gift |
Leather case for taking it outside.
For those who want to take their
corebacca out for camping, picnics, etc., we offer a dedicated leather case.
It comes in three colors: tan, black, and camel.

It protects the blade while carrying it,
so you can use it for cooking outdoors or while traveling.
*The leather case is an optional accessory for carrying.
For home storage, we recommend the dedicated wooden case.
Tan
Black
Camel

A small knife at the core of your life.
The name corebacca was born by combining
"core," which supports daily life, and
"bacca," which represents the fruits of daily labor.
There are days when a large knife is necessary.
But not every day.
For breakfast, for lunchboxes, for dinner prep.
When you decide to cook, your hand naturally reaches for it.
After using it, you might suddenly think,
"I used this one all the time today too."
We hope this knife becomes such an essential part of your kitchen,
always there to support you.
