4-piece whetstone set / Large whetstone + 3 artificial nagura stones (Showa era, practical use)

This is a set of 4 whetstones from the Showa period, sold as a bundle.
The set is designed for practical use, allowing you to perform a full sharpening process.

- Large whetstone (approx. 20cm / 792g)
  Equivalent to a medium grit whetstone (for edge setting and base preparation)
- 3 Nagura stones (Green, Brown-Black, Yellow)
  Artificial Nagura (for creating slurry and aiding in finishing)

By wetting the Nagura stones and rubbing them on the whetstone surface, you can create a polishing slurry (mud) to adjust the sharpening feel and finish.

There are no markings, but all stones are in usable condition.
You can enjoy a different sharpening experience compared to modern stones, with the characteristic texture of Showa-era whetstones.

As these are used items, there are scratches, dirt, etc. Please check the photos for condition.
