In our tests, the Chef’sChoice ProntoPro 4643 took seriously dull blades—we ran them against a chunk of concrete curbstone until they were all but useless—to tomato-filleting sharpness in less than a minute. And like all our picks here, it’s far easier to master, and far cheaper, than traditional sharpening stones or modern jig systems. Effective, affordable, simple to use, and easy to store, the ProntoPro 4643 is the clear winner for most people.
You shouldn’t use this stone often, as it will wear your knife down. The #2000 and #3000 grit stones can be used more often if you are the sort of person who likes to sharpen a bit more regularly as they are less coarse, but again, they are designed for sharpening and not maintaining your edge.Once you get into a routine, you will get to know how often you need to use your medium stone.
Grit choices should fall in line with the steel used to make the knives you plan to sharpen. If your knives are all European, relatively soft steel knives, then you could finish off your knives at the 1,000 – 2,000 grit level. There is a lengthy explanation regarding this topic but suffice it to say that at 2,000 grit, these knives can be made extremely sharp.
All stones require either water or oil as a lubricant to sharpen the knife. We prefer water stones because they’re easier to use, less messy and don’t have the possibility to go rancid like oil does. If you choose a water stone, all you have to do is either add water to the stone before placing the knife on the surface, or soak the stone in water for 10 minutes before use. You’ll want to read the instruction for the stone you purchase to find out how to use it properly.
Aesthetics – While it’s true that most people keep their sharpener, (even their expensive mechanical sharpeners) in the drawer until it’s time to use them you’ll still want to be aware of whether your sharpener fits into the overall aesthetic of your kitchen when you do take it out to use. While sharpener designs are fairly limited to be sure you typically have some control over the color and finish of the device as well as design factors like whether the device is boxy or rounded in appearance. With a stone sharpener or a stick however you pretty much get what you get.

A common myth is that sharpening steels actually sharpen knives, and can replace stones or other sharpening devices. Steels actually hone a knife and help keep its edge if used regularly. A steel should be used before and after each knife use for proper maintenance. Easily enough, it's used the same way you use a sharpening stone. To find the proper angle, hold the knife horizontally with the edge touching the steel. Move the spine upward to create a 45-degree angle, and then half that again for your optimal sharpening angle.
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.
