A chip saw in which chips are brazed onto the peripheral edge thereof is clamped, and is rotated while bringing a rotational brush into contact with a honing-subjected portion of the peripheral edge. A liquid, which has dustproof oil and abrasive powder, provided with abrasive properties is supplied to a part in which the rotational brush is in contact with the honing-subjected portion. Therefore, the work efficiency of honing process is improved, and sawdust is not generated. This makes it possible to easily take countermeasures against environmental problems and effectively use resources. In addition, the liquid can be easily recycled.
