|MONOCRYSTALINE DIAMOND HONES. Our DMT sharpening hones use monocrystaline synthetic diamonds, and will last several times longer than other diamond sharpening products made with polycrystalline synthetic diamonds (which are meant to break down during lapping.) The solid diamond coating is bonded to a heavy, flat steel plate. (Your curved and smaller tools won't drop down into the holes of a polka-dot grid.) We recommend using water as a surface cleanser; about once a minute, splash a small amount of water onto the surface with a small brush. Honing oil tends to clog the surface.
These sharpening hones are manufactured by DMT, a pioneer manufacturer of synthetic diamond sharpening products. The flat steel hones are available in three sizes and four grits. The 2" x 6" hones (which are 1/4" thick) are for general purpose honing of plane blades, chisels, gouges, kitchen tools, etc. The larger 2-1/2" x 11-1/2" hones utilize 3/8" thick solid steel plates. These larger hones are particularly useful when using a honing guide, and for safety when you secure a tool in place (with a vise or clamp) and then rub the hand held hone over the tool's edge. The 7/8" x 4" inch hones are 3/16" thick.
The new 220 grit (60 micron) is so aggressive that it can often take the place of a powered grinder. (But with no fear of overheating and losing temper.) Available in 2 1/2" x 11 1/2" size only. The 325 coarse grit (45 micron) is useful for light shaping work, general sharpening, light filing, and de-burring. 600 medium grit (25 micron) is for quick cleanup of cutting edges that are in generally good condition before going on to fine honing. 600 grit is also recommended for sharpening pocket knives and most kitchen tools. The 1200 fine grit (9 micron) products are for finish honing. For the ultimate in woodworking tool sharpness, we recommend final polishing with a Japanese water stone (4000-8000 grit) or a hard felt buffer.
I'm sending an order for 2 more of your diamond stones. The ones I bought 10+ years ago and use in my knife making are STILL very servicable, just a little finer... All these years of tools and knife making and they're still
