Deba is Butcher Knife.

It is used when cutting fish or bones.
We recommend that you use different sizes of Deba knife, such as large Deba, medium Deba, and small Deba, depending on the size of the fish you cut.
Please note that all Deba knives are made to order; therefore, it may take “several months” to deliver it after your orders are received.

As our kitchen knife is very sharp, we recommend that you use a chopping board made of unfinished soft wood. Wash, wipe, and let it dry after use to keep it clean and hygienic. If you feel the knife are not sharp, you need use sharpening stone to maintain it. Aogami Steel easily gets rust and requires good maintenance.

By sharpening regularly, the product lasts for a long time. Contact us for the maintenance or if you need any assistance. 

What is kurouchi knife?

Kurouchi knives retain the scaly residue left from the forging process, meaning that the residue works as coating on the carbon steel to prevent from rust.
The finish of Kurouch reduces reactivity on carbon steel knives, and give the knife a very characterful, rustic aesthetic prized by many knife enthusiasts.
Kurouchi finishes varying widely in appearance, uniformity, and durability. Rarely do pictures do these finishes justice as they have a very complex look and feel to them.
Of course, you need to sharpen the edge every time after using it even if the Kurouchi coating works for the sides of blade.

TOSA traditional skill “Free Forging”

TOSA cutlery started from 1621, over 400 years ago. Forge to finished need many steps, all steps just made from one blacksmith. Easy to control every part and keep it free style to forging, because that’s made by same craftsman. So, that’s why call this skill to “Free Forging”.

With the sound of a violent blow sparks, the way thick steel is transformed into a kitchen knife in the blink of an eye is truly craftsmanship. By hitting it many times with a hammer and stretching it, impurities come out, by making the structure “dense”, it becomes a knife with high hardness and stickiness.

    You can see the marks of the hammer that was struck up with a hammer, it has the characteristic of being handmade by craftsmen and resistant to rust compared to polished finishing.

    KUROUCHI forging with different color for every cutlery. TOSA “KIYOKANE” and “MOTOKANE” with additional process of kurouchi knives. On every knife have different color.

    This knife isn’t using press process and solvent to make the pattern of knife, The final pattern and color of knife just depend on oxide film by random. So, the one and only knives. 

    So many situations can use that double bevel knife. Double bevel knife with more tough of edge than single bevel, and easily to handle, good for Japanese food and western food.

    Because free forging, can be easy to innovation.
    The knife is consistently performed by a single craftsman, without being bound by the framework of the process, so can continue to improve and evolve.

    This knife isn’t mass production.

    We are focus on the knife quality than productivity. You can feel the soul of craftsman. We recommend you use that for gift.
