Product Description

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.

Norton Abrasives manufactures sanding, grinding, and polishing abrasives, and has been located in the United States since 1885. Norton, now a brand of Saint-Gobain, meets ISO 9000 and 14001 certification for quality and environmental management standards.

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.

This is my first waterstone, but I have used them before in restaurants and know a good one from a dud. The 1000 grit side (brown) brings back an edge to a slightly dulled knife in just a couple of minutes, and the 4000 grit side (white) refines that edge further and slightly polishes the blade. I've used this stone on carbon steel knives, inexpensive stainless steel ones, and rather pricey stainless steel ones. The results with all of them have been excellent. There is a somewhat steep learning curve with these stones; it's easy to get a knife sharper than it was, but tricky to achieve the sort of edge that you're probably after if you're considering a whetstone. Regardless, I highly recommend this stone. The price may seem daunting, but considering how rarely you'll need to use the stone after your initial sharpening (a honing steel is sufficient for regular maintenance, in my experience), it will last a very long time. Other advantages include the larger than average surface area of the stone, which makes sharpening long or wide knives much easier than on the smaller, more common versions of stones that are popular, and the carrying case, which doubles as a sturdy stand.

The first one I got was chipped; returned to Amazon and the 2nd was perfect. Sharpens very well. A couple of my knives had nicks. The 1000 grit fixed them...eventually...but it took a lot of patience. I'd get a courser grit (in addition to this stone) next time I work on knives that need TLC. Best advice was a) watch a few howto videos on youtube about using a waterstone; and b) get an angle guide. Holding the knife at a consistent angle is essential (and tough in the beginning).

This stone works very well in sharpening knives without taking a lot of metal off of the knife. Highly recommended.

Teaching a high school culinary class, the students put a hurting on the knives. I'd never used a water some before but just admit I'm almost liking these better than my tristone.

As noted, this is for those who already know how to properly sharpen knives. You must be able to hold the knife at the proper angle during the sharpening process.

That said, these two grits are about what one might need for most applications. The brown will take a mediocre blade and put a good edge on it. Flip that bad boy over and finish the process. As long as that stone has water for lubricant it works quite well.

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.

very good quality stone. Needed flattening out of the box, but not much. The stone is a great combination and puts a very nice edge on any blade. The 4000 grit leaves a very sharp "toothy" edge, probably good for most people and is a good intermediary stone before going to the 8000. I was concerned about grit contamination with a combo stone a quick run under the faucet before going to the higher grit is all that is needed. The large size of these stones makes sharpening even twelve inch chef knives a breeze.

Originally purchased the one thousand to four thousand grit Norton Stone for honing straight razors, found out it was to rough then somebody told me to purchase the four to eight thousand grit Norton Stone ( to put a more refined edge on your straight razor ), well it worked to perfection! Word of Warning though - It's very expensive - but it's a very smart and worthwhile investment. If you learn how to hone your own straight razor's you won't have to pay through the nose to get them sharpened somewhere else.

you are ready to get sharp ! We had several knives that we had given up on. We got this waterstone due to a review I saw on a knife forum. It is great. My husband watched a you tube video and then took one of our cheapest knives and started to practice. WOW...I now use that old knife a LOT ! It takes a little time and practice to get the technique down but after that you will have all your friends asking you to sharpen their knives too.
