Description: CBN sharpening stones, Poltava 200 х 70 х 3 Length: 200 mm = 7.9 inchWidth: 70 mm = 2.8 inch Thickness: 3 mm = 0.12 inch Material: CBN - cubic boron nitride. It has the best cost/productivity ratio for processing of STEEL, comparing to diamond and cheaper stones. CBN is a generic name, there are also other names of this material, depending on manufacturer: borazon, elbor. CBN stones are similar in qualities to Japanese wet stones, have have ten times longer working life. CBN grit: any, please select from the list. Please refer grain size conversion chart below. There's also aluminum blank 200-70-10 in grain selection window, just in case you need support plate for these stones. It can be attached to stone with double-sided tape. I sell blank if you buy stone. Metal bond. Concentration 100%.Flat solid block. PreparationStones with grits finer 3 microns either require preparation on cast iron plates, or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well. This is common issue for all manufacturers, unless stones are prepared before shipment (cost 10usd). So there's "Stone preparation" option in grain selection window. Use and cleaningUse any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush. Maintenance is only needed every year or two.In 1-2 years you may need to flatten stone, 20 mins with Ferric chloride (FeCl): - 10 mins setting in 25% mixture (25 gr FeCl per 75 gr of water),- 10 mins polish movements (carefully draw "8") on glass plate. You may buy 100 gr. FeCl in grain selection window. I sell it if you buy a stone. Please review stone flattening/revitalization video below.
