Feature
Oya Seisakusho's pure copper grater
Oya Seisakusho's pure copper graters are hand-forged by artisans, producing fluffy, watery grated daikon radish. The irregularly shaped, sharp blades preserve the flavor of the ingredients, and the more you use them, the more you appreciate their quality—a tool you can use for a lifetime.
What is an Oya Seisakusho grater?
These handmade pure copper graters are made by repeatedly hammering thick copper plates, then hand-carving each blade. The irregularly positioned blades allow new surfaces, such as daikon radish and wasabi, to come into contact with the blade one after another, resulting in efficient grating with just the right amount of moisture.
What Makes This Artisan's incense So Special
- By hammering the copper plate to harden it, we achieve strength and a sharp cutting edge.
- The irregular blade, hand-carved by artisans, cuts without crushing the material.
- Resharpenable, durable for years of use.
The workshop
Saitama, Japan
Oya Seisakusho is a workshop that has been making copper graters for three generations. The process, in which artisans hammer and manually sharpen each blade, is so laborious and time-consuming that they can only produce about three graters per hour, or about 24 per day. Even now, with the number of copper grater makers in Japan dwindling, Shigeki Oya continues to create tools that can be used for decades, repairing them as he believes in "making things that bring joy to the user." The tradition continues to be preserved today, with the sound of the hammer echoing from morning to night.
