Product Description

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.

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.

I use the Japanese style stones to sharpen all my knives, as well as straight razors I shave with. They are a little different than the standard stones, but if you want a truely 'razor sharp' blade, this is the only way to get it. Many people say, "my knife will shave hairs." Yes, but can it do it without razor burn? My kitchen knife will shave hairs off my arm, but that doesnt mean Id be willing to shave my face with that blade.

These stones need to be soaked in water prior to use. Only about 20 minutes. More than that can cause problems, they are not meant to be STORED in water. Too much soaking can lead to the stone degrading or the glue splitting the two sides apart as other reviewers mentioned.

This stone is meant to hone more than sharpen. That means you should ALREADY have a sharp knife before you use this stone. If your knife is dull, sharpen it by whatever method you would usually use, I personally use another Japanese water stone Steelex D1067 800-Grit Japanese Waterstone.

The 8000 grit side of this stone will polish the side of a blade to a true mirror finish if you wish. The edge gets the same, but obviously its harder to see. This level of finish causes the blade to be significantly sharper than a 'regular' sharp knife, plus it stays sharp longer and cuts smoother as well.

The only drawback to this type of stone is that they are softer and wear faster than other types. Thankfully, it can be made flat again by using 600-1000 grit sandpaper and a flat surface to rub the stone on. So I find it more useful as I can ensure my stone is always flat that way.

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.

All the reviews are accurate, this is a good stone.

I just want to point out that, as some of the other reviews mentioned, the stone will not arrive perfectly flat. If you are going to use it on a straight razor, or other ultra sharp blades, this is critical. Uneven stones will mess up your cutting bevel.

Mine had to be re-flattened on both 4000 and 8000 sides, wasn't even close. You don't sacrifice much material but I feel something that is meant for sharpening should be ready to sharpen when you purchase it new.

So if your like me, and not an experienced razor sharpener, do your research on a flattening method.

I went ahead and purchased the Norton flattening stone after the fact. I should just bought the whole set it would have saved some cash.

So if your after a fine honing stone, the 4000/8000 works great but be sure to pick up a flattening stone and Prep (Nagura) Stone.

It's a good stone, does what it needs to. I use mine for maintaining and honing a straight razor. HOWEVER it is my civic duty to tell you something that Norton does not: It is *not* ready to use out of the box! For reasons beyond my understanding, The stones *do not* come out of the factory perfectly flat nor of the right abrasiveness. You have to slurry the stone with either a Norton slurry stone or a waterproof sandpaper on a flat surface. I used a 400 grit sandpaper to get it flat, then the Norton approved 600 grit (on both sides) to get it to the proper abrasiveness. I have verified this with several forums, all with people who universally have the same problem - its not ready to use as-is. Once flattened it is ready to use and lasts a while before needing to be re-slurried. I was happy with the size/weight of it, and the storage box doubles as a honing stand.

TOO LONG DIDN'T READ: Good stone, does what it needs to, needs to be slurried before initial use.

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.

I purchased this stone to hone my straight razors and keep them shave ready. I have had little experience honing my own razors, however, after spending a week searching forums and watching youtube videos that teach honing techniques, I quickly found that this stone is the one most often used by straight razor enthusiasts. Considering my limited knowledge of honing techniques that I studied from the forums, my razors came out super sharp with a smooth polished edge which gave me a comfortable shave. I owe this to the good advice I researched to some degree, but the lion's share of the credit goes to how well this stone works and how easy it is to use. When removed from the box, the box is designed to be used as a stand and since honing razors requires a gentle touch, its stability was more than adequate.

When I first purchased this stone I didn't want to spend $73, but I thought in the long run If it works it will pay for itself. A professional honing usually costs between 25-40 dollars. Now that I see how well it works, I wish I would have purchased the Norton waterstone starter kit which sells on amazon for about $137. At first I thought that was too much money and would not get much use from it. Looking back that was a mistake. Now that I see how easy it was to learn honing (about 2 days of practice before reaching good results) I plan to maintain all my own razors from now on and my results will get even better with practice. The first hard lesson was that I had to use the 1000/4000 grit stone to both set the bevel and polish the edge followed by micro abrasives and stropping. Setting the bevel was slow because the 4000Grit side was too smooth to really bite into the blade.
