(Also known as FUJITORA)
Quality stones made in Niigata, Japan.
If you have a stone you need this!
No more ridges or valleys in your Whetstones!
This stone restores your other stones to a flat level allowing accurate sharpening. (Draw lines across your other stones using pencil to reveal your flat spots and wear.)
Probably the most underrated stone and its also the cheapest!
Recommended for anyone who owns a stone.
