Take your sharpening anywhere with the portable Dia-Sharp® Credit Card Diamond Sharpener. Fitting easily into any pocket or wallet, it also comes in a convenient, grit color-coded vinyl carry case. This kit of three is equipped with a coarse diamond stone (45 micron / 325 mesh) to quickly restore a neglected edge, a fine diamond stone (25 micron / 600 mesh) to hone a razor sharp edge, and an extra-fine diamond stone (9 micron / 1200 mesh) to polish and refine a razor edge after sharpening with a coarser diamond. Each stone is also conveniently sized at 3 1/4" x 2" x .05". Thanks to its micronized monocrystalline diamond surface as well, you can sharpen edges 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. Made in the USA.
