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 24336 Japanese-style 4000/8000-grit combination waterstone creates an abrasive slurry for effective sharpening, with 4000 grit on one face for maintaining and refining a cutting edge, and 8000 grit on the opposite face for polishing 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.

3.0 out of 5 stars combo stone came apart at glue joint, November 30, 2009

I like these stones, though like all water stones, they are quite soft, and require frequent flattening. The problem I had was that after soaking in water for awhile, my combination stone separated at the adhesive that held the two different grit stones together. They still work as two separate stones, but they are now each quite thin, and I don't expect to get as much life out of them. I wish I'd just purchased two separate water stones. You might also want to check out the Shapton stones. They are expensive, but are much harder than Norton or Japanese water stones, and so don't groove so quickly.

Excellent, I use this stone to sharpen my straight razor. I bought the straight razor at an antique shop which is where you can find the better ones made out of German material. brought it home used the 4000 then the 8000 which really gets close to a mirror finish, then stropped before using it. Big difference before and after the stone touched the blade. I'll reccomend this to anyone, especially for those who have the straight razor. The width of this stone is perfect for the blade and you can easily put it away after your done.

These are, literally, Norton engineered stones: therefore different from more conventional Japanese waterstones in look and feel. As a dedicated straight razor combo stone it does wear flat. The 8000 side does not require prolonged soaking nor a slur. This, combined with a 3" width, makes for a convenient razor stone. This combo is the only stone needed for razor maintenance. (The often recommended twice yearly honing of a razor is inadequate.) Shopping around may save you a few dollars.

Wet 320 wetordry sandpaper on a flat (counter) surface can be substituted for a flattening stone. This can be done at each sharpening, and does readily produce a slur.
