The price is for only one piece. Each weights about 130-139g. Randomly selection based on stock situation.
We import very rare and famous natural whetstone "nagura" from Mikawa Aichi prefecture, Japan. Soft grit abuot 4000-5000. Each stone comes with natural light yellow/brown stripes, and already flattened 2 or 3 sides.
Nagura whetstone can clean large sharpening stone clogged with iron dust, and produce fine mud to help sharpening much more smoothly. We recommend use nagura with stone over 4000 grit.
