The Chosera 400 Grit Sharpening Stone is a high-end, coarse-grit tool from the Naniwa Professional line. It is constructed with an aluminum oxide abrasive and a magnesia binder, resulting in a fast-cutting, hard, and highly wear-resistant stone. This 400 grit stone is purpose-built for aggressive material removal, making it ideal for repairing chips, removing nicks, fixing severely blunt edges, thinning blades, and rapidly establishing new bevels. It leaves a toothy edge and is known for producing a scratch pattern finer than typical 400-grit stones. The stone is a "splash-and-go" product and must be used with water as a lubricant. Prolonged soaking is not recommended; only a brief wetting or spraying is required before use.
