The analysis of use-wear “polish” variation and differences according to rock types contributes to the study of the “polish” formation process. The examination of the polished surface on andesite, rhyolite and a hard variety of slate with the SEM and optical light microscope thows that the polished surfaces are produced by mild wear. This provides a basis for use-wear analysis of stone farming tools made of these rocks, which come from early Japanese rice paddy cultivation contexts.
