This axe sharpening stone has two grinding faces; one course side (180 grit) for damage repair and a smooth side (600 grit) for sharpening.
Compared to natural sandstone, this ceramic stone has a finer grain for more precise sharpening. And because you’ll use the finer side more, the 600 grit side is thicker than the 180 grit side. Usually used with water as a lubricant, but can be used dry.*Protective rubber case included.
