I use what I simply refer to as coarse, medium, and fine diamond stones. The manufacturer refers to them as coarse, fine, and extra fine. The coarse one is about a 300-grit (American system equivalent.) The medium one is a 600-grit and the fine one is 1,200-grit.
The 300 grit stone is best used to work small surface areas like narrow chisels and knife tips where greater pressure per square inch can be applied. For larger surface areas or to flatten the back of chisels and planes, it is best to use a 600 or even 1200 grit diamond sharpening stone.
The 1000-grit blue side was the coarser of the two, while the 6000-grit was finer.
The lower the number, the larger the diamond particles, and the coarser the grit size. Conversely, the higher the number, the smaller the diamond particles, and the finer the grit size. Diamond grit sizes typically range from 16 to 3000, with 16 being the coarsest and 3000 being the finest.
It is easy to forget that the back of the chisel is just as important to finely sharpen or polish as the bevel. We recommend at least 2 or 3 more grits to get all the way to a polished edge. Common examples of finer stones would be 600-1000, then 3000-5000 and finally ending with 6000 - 12,000.
In our testing, diamond stones cut the quickest of all types for both shaping and initial honing. But because they come only in grits from 120 to 1,200, you'll need to supplement them with waterstones or ceramic stones of finer grits for final honing, making diamond stones the costliest option (for half the process).
This is done fastest using a rotary buffer with a wool pad and the Meguiar's Ultimate Compound. f you don't want to spend a ton of money then I'd recommend the Griot's Garage 6" DA Polisher.
There are many types of diamond blade, and they have many uses, including cutting stone, concrete, asphalt, bricks, coal balls, glass, and ceramics in the construction industry; cutting semiconductor materials in the semiconductor industry; and cutting gemstones, including diamonds, in the gem industry.
Flawless is the top grade in the GIA Clarity Grading System. Diamonds graded Flawless don't have visible inclusions or blemishes when examined under 10-power (10X) magnification by a skilled and experienced grader.
Start with your lower grit whetstone. For kitchen knives, a good starting point is 1000 grit for the first sharpening, and 6000 grit for finishing/honing, so they're the numbers we'll use in this guide.
For repairing chips, broken tips or thinning, we recommend a very coarse, 220-grit sharpening stone. For the first step in sharpening a very blunt knife, we recommend a coarse, 400-grit stone. For the first step in sharpening undamaged and regularly maintained knives, stones with 800-2000 grit are a good choice.
Honing oil SHOULD NOT be used on the diamond hones, honing oil will clog the diamond coating.
Ultra Sharp II Diamond Stones. Ultra Sharp Diamond Sharpening Stones are the best value we've ever seen in a diamond sharpener. It is a quality stone and the first stone we grab for around here. These extremely fast honing diamond sharpening stones are available in 300, 600 and 1200 grit.
Diamond stones are very low maintenance. They don't need flattening, the surface doesn't need prepping before use and they can even be used dry. That said, we recommend using a cutting fluid, such as water, to rinse away the swarf (metal particles) left behind during sharpening.
The most commonly purchased diamonds are those that are near-colorless, often with a faint yellowish tint, falling around the G to J range in color. These are more common than completely colorless diamonds, yet in most cases appear white or clear to the naked eye.
While you'll find diamond ore anywhere from Y-level -16 and below, the best Y level to mine diamonds is anywhere between Y-level -53 to Y-level -61. In terms of the optimum layer level? You're best off heading down to Y-level -53 to find the most diamonds in Minecraft.
Diamonds are separated into five types: Type IaA, Type IaB, Type Ib, Type IIa, and Type IIb. The impurities measured are at the atomic level within the crystal lattice of carbon atoms and so, unlike inclusions, require an infrared spectrometer to detect.
Forcing the blade may cause overheating or blade damage. Don't cut or grind with the sides of a diamond blade. Don't allow the blade to deflect in the cut. Don't attempt to cut curves or radii.
#400 grit whetstone is used for coarse sharpening of damaged knives (eg, broken tip, chips or nicks in the blade), or for totally blunt blades if your knives (god forbid) haven't been sharpened in ages.
Selecting the Right Grit Sandpaper
For heavy sanding and stripping, you need coarse sandpaper measuring 40 to 60 grit; for smoothing surfaces and removing small imperfections, choose 80 to 120 grit sandpaper. For finishing surfaces smoothly, use extra fine sandpaper with 360 to 400 grit.
Moving onto 2000 grit, using the same process, at this point, all the orange peel should have been removed and now you're only left with preparing the paint for polishing, removing those coarse sanding marks.
For polishing stones and rocks, a progression of grits is typically recommended, starting from around 80 to 120 grit for shaping, moving to 220 to 400 grit for smoothing, and finally using 600 to 1200 grit for polishing.
