About pattern exchange

Prices for re-patterning vary depending on the type and size of the knife. The handle of the Japanese knife can be exchanged on the spot.
If the core is badly damaged, such as rusting, it will take days and additional labor to repair.
Normally, we will attach a handle that matches the blade of the knife, but it is possible to change it to another type of handle upon request.
It takes about a month to replace the handles of Western knives because it is sent to a specialized craftsman.
We recommend that you replace the handle of the knife before the damage becomes severe.
If you continue to use a knife with a handle that has become thin due to use or has cracked due to corrosion, water will easily enter the core, and if you continue to use it as it is, the core will become brittle and break during use. Fear emerges.

Concrete example

Cutting edge becomes dull, or edge retention does not last long

Sharpening cost: 1,100 yen (Sharpening fee: 1,000 yen + Consumption tax: 100 yen)

※ The total amount varies depending on the size of the knife and how badly the blade is damaged.

A small chip is ground, and the cutting edge is thinned while judging the thickness of the knife and the properties of the steel material. As a result, it will cut into the ingredients well as before and it becomes easier to sharpen the knife by yourself. In the case of ordering repairs by mail, it takes about a week to finish repairing.

Cutting edge is greatly chipped (the shape has been lost and it’s difficult to use)

Repair Cost: 2,200 yen (Repair fee: 2,000 yen + Consumption tax: 200 yen)

※ The total amount varies depending on the size of the knife and how badly the blade is damaged.

Considering the balance of the entire knife, the chip is ground to remove and repaired to an easy-to-use shape. Please note that the cutting edge becomes narrower after repairing. As the knife is entirely repaired to reshape, it usually takes about a week to finish repairing either when you come to pick it up or send it back by mail.

The surface of Western-style kitchen knife has rusted

Repair Cost: 1,650 yen (Repair fee: 1,500 yen + Consumption tax: 150 yen)

Rust on the surface of the knife is removed and we sharpen the blade to be shiny. Please understand in advance that if the rust is deep, the engraving and mirror surface processing of the blade may be removed, and all rust may not be able to be removed. It usually takes about a week to finish repairing either when you come to pick it up or send it back by mail.

The back of Japanese style Kitchen Knife

Repair Cost: 2,200 yen (Repair fee: 2,000 yen + Consumption tax: 200 yen)

※ The total amount varies depending on the size of the knife and how badly the blade is damaged.

The back of the blade (urasuki), which is slightly depressed and curved as a characteristic of Japanese style kitchen knives, is re-made to its original state. Please understand in advance that if the rust is deep, the engraving and mirror surface may be removed, and all rust may not be able to be removed. It usually takes about a week to finish repairing either when you come to pick it up or send it back by mail.

The handle of Japanese style kitchen knife is damaged, cracked or broken

Repair Cost: 3,410 yen (Sharpening fee: 1,000 yen + Nakago tang welding: 1,600 yen + Plastic collar: 500 yen + Consumption tax: 310 yen)

※ The total amount varies depending on the size of the knife, how badly the blade is damaged and the type of handle.

The handle of the Japanese style knife is replaced with a new handle. In addition, even if the tang (nakago) inserted into the handle is worn out, a new nakago tang can be welded and a new handle can be replaced. If you’re only exchanging the handle you can come to the store and ask for a same day repair. If you request the repair by mail, we will repair it and return it the same day it arrives. * Please note that if welding is needed, it will take about 1 month to finish repairing. Several types of handles are available, such as a magnolia handle with a plastic collar, a chestnut shape magnolia handle with a water buffalo horn collar, an octagonal magnolia handle with a water buffalo horn collar and an octagonal ebony handle with a water buffalo horn collar. (The price varies depending on the type of handle.)

The handle of the Western-style kitchen knife has been damaged, cracked, or taken off

Repair cost: 6,270 yen (Sharpening fee: 1,500 yen + Replacing new handle: 4,200 yen* + Consumption tax: 570 yen)

*Depending on the condition, it will cost about 4,000 to 6,500 yen only for replacing the handle.
※ The total amount varies depending on the size of the knife and how badly the blade is damaged.

A new handle is replaced to fit the knife. It is possible to repair even if welding is needed as the blade is badly damaged, If the blade is damaged badly enough we will use the Tsuba part (metal part between the blade and the handle) to repair and weld it. We will not replace the Tsuba part so the knife will become slightly shorter. In addition, please note that the shape and material of the handle may not be exactly the same as the one you have. It usually takes about a month to finish repairing, either when you come to pick it up in person or it is sent back by mail.
