NAGURA Whetstone

The role of Tennen Nagura is to remove mud from natural whetstones, which are difficult to get mud from.

But when used on an artificial whetstone, natural mud is transferred to create a natural-looking sharpness.

The role of the artificial Nagura is to clear the clogged grindstone, by using it with a whetstone of a different grit, you can achieve a finish that is a little different from the original grit.
