What causes blade spillage?

Hello.

Today, I would like to explain one of the most common problems we see with kitchen knives, which is the “edge spillage”.

The knife in the photo is an all-purpose Santoku knife purchased from us.

It is our original product manufactured by a long-established manufacturer in Tsubame-Sanjo, Niigata Prefecture, using a hard and long-lasting high-purity steel material called “aogami No. 2” made by Hitachi Metals.

This time, we received a request from a customer to repair a kitchen knife that had suffered a major blade spill.

What kind of usage causes this “blade spillage”?

The main cause is that you try to cut “hard foods”.

For example, frozen food and bones.

It is a common misconception that a sharp knife can cut anything.

A sharp knife has a “thin” blade, which is very delicate in exchange for its sharpness.

Soft foods can be cut cleanly, but there is a risk that the blade will chip easily when cutting hard foods.

In mail-order programs, there are frequent performances of cutting hard foods to express the sharpness of knives, and this has created misunderstandings among viewers.

New kitchen knives made in Japan have particularly thin and sharp blades, and foreign customers often have problems with chipping blades.

Conversely, knives whose sharpness has dulled after long use may have thicker blades and are less likely to chip even when used in an unreasonable manner.

In some cases, such knives with thicker blades are suitable for certain purposes.

Spilled blades are one of the most important issues to pay attention to when selling knives.

It is important to listen carefully to the customer’s needs and suggest knives suitable for the intended use.

In order to do so, the dealer must also fully understand this problem and have the appropriate knowledge.

The kitchen knife we received this time had a major blade spill, but our repair brought it back to sharpness again.

If you are suffering from similar symptoms, please contact us and we may be able to repair it.

If you are ever in Kappabashi, please stop by Kamata Hakensha.

See you soon.
