Naniwa has redesigned its packaging and made some changes to the names of its popular stones. The stones themselves remain the same but the packaging and names have been updated. Here’s a guide to help you navigate these updates.

Naniwa Diamond Pro

The Naniwa Diamond Pro Stone is a sharpener with a 1mm thick diamond abrasive bound in a layer of resin, mounted on a sturdy metal base.

All of these products remain the same sharpeners you know and love. It’s just the names and packaging that has changed. The stones are still made of the same materials and the item numbers will remain the same. During this packaging and labeling change, you may receive a product with the old or new packaging. When you purchase more than one stone, we will do our best to provide you with stones that have matching labels and boxes.
