🏠NSK Kogyo Diamond Sharpening Stone - Komon

This video introduces the sharpening stones that Ivan uses in his sharpening work.
In his stone shelf there is many stones but the stones Ivan picks up in the video are those that Ivan in particular daily uses or could use in his work really well. Even with this, only carefully selected sharpening stones that are used at work are concentrated on the shelves. All of the stones look similar at first glance (especially Uchigumori), but they all have different characteristics, so it is fun just to watch(shoot and editing for me) the slow-motion video.
Also, I would love to hear your opinion about Unknown stones!
