Product Description

From the Manufacturer

Waterstones are synthetic stones designed to be softer than oil stones. These softer grade stones are used with water as the lubricant (versus oil) to develop fast-cutting slurry. Designed in a carefully planned and efficient sharpening sequence. You get the level of abrasiveness that you need at each stage, without wasting time trying to sharpen your knives on a grit that is too fine, too soon.

Product Description

The Norton 24450 Japanese-style 1000/4000-grit combination waterstone creates an abrasive slurry for effective sharpening, with 1000 grit on one face for establishing a cutting edge, and 4000 grit on the opposite face for maintaining and refining cutting edges; this 1 x 8 x 3 inch (H x W x D) stone, suitable for bench use, cleans up easily with water, and comes encased in a blue plastic hinged box. (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The box protects the waterstone and provides a reservoir to keep it moist. The removable box lid, with no-slip rubber feet, acts as a sharpening station to hold the waterstone in place during bench use.

This synthetic waterstone is created by grading abrasive material to a consistent particle size and blending it with bonding agents. It is then molded and surface-finished. Waterstones have a finer grit and softer bond than oilstones, and use water as the lubricant to develop a slurry, a thin paste of abrasive grains and water that removes metal with less pressure than an oilstone requires. Cleanup is easier than with oil as lubricant. The use of waterstones originated in Japan, where such stones occur naturally. As a result, some synthetic waterstones may be called “Japanese-style.” However, whether natural or synthetic, and whether labeled “Japanese-style,” all waterstones have the same basic characteristics. This stone conforms to the Japanese Industrial Standard (JIS) for waterstones.

Sharpening stones, or whetstones, are abrasive surfaces used to sharpen and hone the edges of steel cutting implements such as chisels, knives, scissors, hand scrapers, and plane blades. Sharpening is the process of creating or re-establishing a cutting edge by grinding away portions of the metal to adjust the angle of the edge and reform the shape. Honing removes small imperfections. Stones can be flat, for working flat edges, or shaped, for edges that are more complex. Sharpening stones are made of natural or synthetic materials that range from softer to harder, and are categorized by the size of their abrasive particles, known as grit. A stone with a coarser grit is used when more metal needs to be removed (e.g., when sharpening a nicked or very dull blade); the stone with the finest grit produces the sharpest edge. Where numbers are assigned to specify grit, they range from coarser grit (low) to finer grit (high). Some sharpening stones are designed for use with a lubricating liquid, some can be used dry, and others can be used either wet or dry. When used with lubricating liquid, a sharpening stone can be called a waterstone or an oilstone, based on the lubricant required.

good all in one waterstone. i suggest getting lower grit for shaping heavily miss shaped knives (really dull). but if you want to just get one stone this is a good buy. the carrying case doubles as a platform, that is a big plus.

Good choice for kitchen knives, and lower HRC knives. Don not use it to hone steels like D2 or VG-10, that will hurt the surface of this water stone.
