Fitting conveniently in the palm of your hand, this compact “Oroshigane” (卸金) copper grater is perfect to use for condiments such as ginger, wasabi, garlic, or citrus. Each grater is carefully chiseled one-by-one by skilled craftsmen in Japan, then plated in tin for extra durability and rust prevention. The irregular arrangement of blades resulting from handcrafting is what makes the grated foods especially flavourful, as the moisture does not get separated from the fibre when shredded. 


The gracefully curved sides of this grater add a warm depth to the shape, while also creating a border around the edge to help prevent spillage. So, not only does this grater provide great function, but it is also very beautiful. When not in use, you can proudly display it on a hook in your kitchen or you can even collect different shapes to create a charming wall arrangement.


*Recommend to use with a bamboo scraper to remove fine food fibres.


Always be careful of your hands and fingers when using this grater, and keep out of reach of children. Over time, the copper will change in colour and develop a patina. This patina is harmless and will not affect the taste of your food.

How to care

  • Wash once with dish detergent before use for the first time.
  • Do not use with hard objects, such as frozen foods, as it may damage the blades.
  • After every use, immediately wash with water and dry with a cloth.
  • Use brushes such as Tawashi to remove food fibres and remains.
  • Do not soak.
  • Do not wash with chlorine bleach, harsh cleanser, steel scrubbing brush, dishwasher, or dryer.
  • Salt, acid, remaining foodstuffs, and moisture can cause discolouration. Due to the nature of metal, the surface discolorus over time. Depending on the temperature of the storage location, the color may change even for a short time. Even if it discolours, there is no harm in using it as it is.

The copper oxidizes naturally over time and use, and gradually create rich patina. Although patina on copper is harmless, if you want to shine it again, please apply a mixture of vinegar and salt to a cloth or brush and rub it. Then wash with water.

As the teeth are very sharp, please be careful when handling them so not to hurt your fingers.


Since 1792

Tokyo, Japan

* * *

Kiya is a company that manufactures hardware such as knives and cutlery in Nihonbashi Muromachi, Tokyo. A long-established store founded in the middle of the Edo period, it is known as “Kiya of cutlery”. Known for their professional kitchen knives, they also handle general hardware such as cutlery, pots & pans, and various scissors for gardening.

The first Kiya store opened in 1573 by an original founder Kyube Hayashi, who served to Toyotomi family as a tradesman of medicine materials in Osaka. Then Shogun Ieyasu Tokugawa invited his brother to Edo, and he opened a store in Honcho (Tokyo). The brother’s store was separated from the Osaka one, so he separated a Chinese character of his family name(Hayashi, 林) into two parts(Ki, 木 and 木), then he named his store Kiya (木屋).

This store traded in fancy goods, Japanese ware and candles, and remained open for centuries. Then in 1792, after working his way up through the company, Iisuke Kato received permission to establish a new store with the same name, “Kiya”, with both stores operating next to each other. The new Kiya store traded in cutlery and other merchandise not being sold at the original store and continues to do so to this day. 

In the great picture scroll Kidaisyoran (1805), you can see the Kiya stores as they were at that time, with their original trademark symbol printed on the shop curtain. This trademark is the same one which is still used today, over two hundred years later.
