(Surface roughness: about Ra0.8μ)
Measurements are taken using a surface plate with a pick test of 1μ.

●Application
・Jig for checking the warpage of blades.
・A jig for checking the flatness of knives, natural whetstones, artificial whetstones, etc.
- Back pressing using abrasive paste.
・Attach sandpaper or the like to the base plate to smooth out the surface of the whetstone.
In addition, please use it for various purposes.

*Since each product is inspected for accuracy, we will accept returns if the flatness is not obtained.
