SKU / Item reference: 有 No.T 50 水

Vintage deadstock item from about 40 years ago, in near-unused condition. Since it was stored uncovered in a box with other stones for decades, there are natural surface scratches, lines, and minor stains. Shape is an irregular 'Koppa' fragment, not a perfect rectangle. No wooden base included. Please check the photos carefully.

Product Summary:

This is a rare, vintage Japanese Natural Whetstone (JNAT) from Kyoto, Japan. It is a "Koppa" (irregularly shaped fragment) finishing stone (Shiage-toishi). This piece was stocked about 40 years ago and has been carefully kept in storage. Since almost all historical natural stone mines in Kyoto are now completely closed, genuine vintage JNATs are highly collectible and increasingly hard to find.

Condition:

Near unused, vintage long-term storage item. Because it was stored uncovered in a box with other stones for decades, the surface has some minor scratches, lines, and natural discoloration/stains. The shape is irregular (Koppa) and not a perfect rectangle. It does NOT come with a wooden base.
