Kit of 3 stones include: Extra-Coarse diamond (60 micron/220 mesh) when significant removal of material is needed for a damaged edge. Coarse diamond (45 micron/325 mesh) to quickly restore a neglected edge. Fine diamond (25 micron / 600 mesh) for a razor sharp edge. No messy oils needed – use dry or with water. Durable construction will provide years of consistent performance and reliable service.
