Coarse Grit (#400, #600, #800) are aggressive, and geared toward stock removal, repairs, and (re)profiling. They are also excellent at removing the deeper scratches from diamond plates. The #400 Chosera is a very solid, hard and aggressive stone that does not wear easily. The #600 Chosera is a softer stone that has a sensational, "buttery"  feedback to it, and excels on harder steels.


Medium Grit (#800, #1,000, #2,000, #3,000) refine the edges on most tools and knives to working sharp levels, and quickly perform maintenance on dulled knives. They are still aggressive enough to do minor repair and profiling work, and they set the stage for the fine grit polishing stones. The #800 Chosera Is still technically a coarse stone, but when used with some mud, it leaves a very good, basic working edge. It is a real workhorse. The #1,000 Chosera is one of the best stones in the series, and is aggressive enough for most maintenance while leaving an edge that is slightly more refined than other 1K stones. The #2,000 grit Chosera is a softer stone, and produces an excellent "good enough" edge on softer steel knives (HRC~55 and below). The #2,000 stone is made even more effective when combined with the #800 Chosera stone. The #3,000 stone is a harder stone, and is the perfect choice for a working edge on a quality knife, and for setting the edge up for the polishing stages.


Fine Grits (#5,000) bring every edge to a whole new level, and where cutting becomes effortless. The #5,000 Chosera is a softer stone, with wonderful feedback. It produces a mirror finish that takes the edge to a whole new level.
