Naniwa Base 220 whetstone is a great rough stone that sets up a new egg in a short time.

It is a relatively soft whetstone suitable for beginners as well as experienced. Suitable for all kinds of knives from customs knives, kitchen knives and various egg tools.

We recommend buying the Naniwa PTC-03 stone holder/case for this stone.

Specifications:

• Roughness (Grit): #220
  
• Type: Soaking stone
• Size: 185 x 65 x 30 mm
• Grinding material: Aluminum oxide

Instructions for use

Place the stone in water and let soak for 5-10 minutes before grinding.
Add water if necessary so that the stone does not become dry during grinding.
Rinse and let the stone dry at room temperature after use.

Maintenance

If the stone starts to become less effective or the surface becomes uneven, you can use a smoothing edge to flatten and clean the stone. We recommend flattening often, preferably after each sanding to avoid the stone becoming uneven over a longer period of time.
