OYA Copper Grater
Overview
Long-lasting grater
Since the copper grater is made of metal, the blade does not lose much weight, so it can be used for a long time.
The copper grater handled by Kamasa Shoten is individually grinded by craftsmen, and is characterized by its ease of grating.

Located in Saitama Prefecture, we are one of the few factories in Japan that specialize in copper graters.
One by one, the grater is carefully selected by many cooks.
3 Key of the copper grater
The flavor is enhanced.
The craftsman's blade does not crush the daikon cells and does not separate the water from the fibers, resulting in a fluffy grated daikon with plenty of moisture even after a long time.
Because the fibers are cut into small pieces, the texture is mellow and the flavor is not lost. Recommended for grating condiments such as wasabi and ginger.


Can be unloaded with light force.
At first glance, the artisan-formed blades appear to be neatly aligned, but in fact they are slightly uneven in spacing and height.
This allows the various surfaces to hit each other each time the food is lowered and allows the food to be lowered smoothly with light force without having to repeatedly change the direction of the food.
be able to make a fresh start
Although this grater has excellent durability, after many years of use, the cutting edge will wear out and the sharpness will deteriorate.
In that case, the old blade can be shaved off and a new blade can be made (for a fee).
In addition to its durability, copper has antibacterial properties and has been used for many years as a tool for professional use.
