The convenient 4" pocket models of the Diamond Whetstone™ and Machinist sharpeners with convenient black fabric tool roll are brought together to provide easy access for all your sharpening needs. This kit includes four different grits of diamond sharpening stones to provide comprehensive edge care. First among these is the extra-coarse diamond stone (60 micron / 220 mesh) for when significant removal of material is needed to repair a damaged edge, followed by the coarse diamond stone (45 micron / 325 mesh) for quickly restoring a neglected edge, a fine diamond stone (25 micron / 600 mesh) for honing a razor sharp edge, and finally an extra-fine diamond stone (9 micron / 1200 mesh) to polish and refine a razor edge after sharpening with the coarser stones. Every stone is also conveniently sized, with overall dimensions of 4 1/3" x 7/8" x 3/16". Thanks to the micronized monocrystalline diamond surface on each stone as well, you can sharpen edges much faster and easier than conventional stones can. No messy oils are needed either, allowing you to sharpen dry or with water. Complete with a durable construction that will provide years of consistent performance and reliable service, professionals rely on the superior quality and versatility of DMT® products for proper tool maintenance.
