Product Details

This is a Naniwa 400 grit diamond whetstone.
I am selling it because I no longer have a use for it.

The diamond layer on the bottom right is thin, and the metal base is visible. Please check the photos.
Due to sharpening, there are areas where the diamond layer is thin. Therefore, it is being sold at a low price.
It doesn't wear down easily, so I believe it can still be used for a long time.
A GC nagura stone is also included, although it is small.
Please use it for slurry creation and to clear clogging.

Immediate purchase is welcome.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
