Review on 💎 Ultimate Precision: Ultra Sharp Diamond Sharpening Stone for Flawless Finishing & Polishing by Glenn Cho

Outside the packaging, they have red large pieces of sand. Use them on an old or low-value item first. After about 30 minutes of use, one or the other large particle will loosen and you can enjoy sharpening. For chisels, drafting knives and planes, I use a belt sander to shape, then a 300 grit diamond bead, then 1200 grit, then stumble across a leather belt. From there just adjust with a sling or 1200 and a sling. As a liquid, I use Prestone windscreen defroster in a spray can. Alcohol and glycol dry faster than water and will not rust. Perfectly removes all honing particles. About 0.25 cents an ounce in a monastery pump bottle.
