Keep your knife razor-sharp with a high-quality sharpening stone. We offer a wide variety of sharpening stones, such as Arkansas stone, Diamond stone, Bench stone, Water stone and more. Whether you own a pocket knife, a hunting knife or a kitchen knife, a sharpening stone is essential for preventing your blade from becoming dull. Most of our sharpening stones are lightweight and portable, so you can use them at home or take them with you wherever you go.
If the blade is only slightly dull, using a steel rod, called knife sharpening steel, can give the edge a quick touch up by realigning the edge, as shown by Cook's Illustrated. Technically, using this method means you're actually honing the knife, rather than sharpening it. For a dull blade, though, a knife sharpener provides the best method of obtaining a sharp edge again.
Oil Stones differ from water stones in that they require the use of honing oil to float the swarf (metal particles). Also, these stones are commonly made from one of three different materials consisting of Novaculite, Aluminum Oxide (Corundum), or Silicon Carbide (Carborundum) and they all use oil to lubricate the stone and suspend the swarf in order to prevent the stone from becoming clogged. Also, while Novaculite and Coticule are the most traditional types of oil stones, there are also synthetic oil stones made by the Norton abrasives company called “India Oil Stones”.
If I am to be completely honest, I must tell you that I actually came extremely close to selecting another manual sharpener for this position. I thought it looked wonderful. It had all the specifications I would hope for in a manual knife sharpener and then some. It boasted the ability to sharpen at two different angles (15 degrees and 20 degrees) and included a honing feature. It looked solidly built. It used diamonds to grind the blades down. It sounded perfect and I almost selected it, until I read the consumer reviews. The consumer reviews for that apparently perfect manual knife sharpener were abysmal.
Sharpening stones consist of coarse, abrasive material bound together to form solid stones. As you run your knife along the stone, the abrasive material will cut away microscopic layers of metal. You can see this metal in the dark paste that will form on the stone called the slurry (more on this later). Lower grit stones will remove metal more quickly, and provide a coarser edge. These are great for re-establishing an edge quickly and removing any dents or chips from your blade. As you increase in grit, the stone particles get finer, removing less metal with each pass and helping to create the polished, smooth edge that makes your knife screamingly sharp.
Start off on the rough grit side of the stone. Check the grit on your stone, or the packaging that came with the stone, to identify which is which. In general, whetstones and diamond stones each have different grits on either side. The rough grit side is used to grind the steel down, while the fine grit side is used to sharpen or hone the knife. The grinding process comes first, so you start on the rough grit side.
Japanese whetstones (also called water stones) – both natural and synthetic – are known for their quick-working qualities, not only for Japanese blades, but also for their Western equivalents. The small particles that do the cutting are loosely bound together in the stone, and so during sharpening with the whetstone, the surface particles are quickly washed out, allowing new, sharp, particles to start working on the blade. These whetstones must be lubricated only with water! Never use oil or other lubricants!
The Presto EverSharp 08800 electric knife sharpener gets great reviews. In our test, though, its flimsy motor instantly bogged down when our knife contacted its sharpening wheels—and even light pressure threatened to stop the the sharpening wheels entirely. The high, wide guide frames meant it couldn’t sharpen the last ¾ inch of a blade, an unacceptable shortcoming. We’ll take our experience over the reviews.
