Why do Japanese knives cut so well?


Why do Japanese knives cut so well?

The blades on Japanese hand-made knives have such a great cutting performance because the blade is made to be very thin.

The blade can be made so thin because they are made with such good-quality materials.

By forging the knives out of hard and tenacious materials, the structure of the steel is fragmented, making it denser, and giving the knife a sharp cut.

 The durability of the sharpness of the blade is an important element in deciding the quality of the knife.

Of course the blade of any knife will dull with continued use, but the sustainability of a "good cutting performance" is what decides the value of the knife.

Using great materials and the hands of skilled craftsmen to create the knife helps to sustain the cutting performance of the knife.


Things to keep in mind


The blades of knives that concentrate on good cutting performance are made extremely thinly.

As these knives can cut well you may think that it will be fine to apply force on the knife to cut harder objects,

but this actually a cause of chipping when used on items such as meat that contains cartilage or frozen foods, so please use specialist knives for these items.


Knives are weak against force from the sides.

If you are used to using knives with duller blades, you may unconsciously end up "cutting by force".

If you unconsciously put too much pressure onto the knife and twist it left and right to cut, you could end up chipping the knife.


Rusting of steel knives is unavoidable.

Rusting particularly occurs for a while after the knife is first put into use.


The best way to keep knives clean is to wet the knife, apply a powdered cleanser (polishing sand), and to use a wet wine cork to firmly rub the surface of the knife.

(Rub until both sides are clean.)


Pro chefs also repair rust on their knives in the same way.

 Then simply wash the knife with water and wipe with a dry cloth.

Repeating these steps will make it harder for rust to form.

 *Even stainless steel knives will experience slight rusting. Please repair these knives in the same way as above.
