A: That depends almost entirely on how often you use them. If you are a professional chef who uses his or her knives every day then you should hone them every time you use your knives. But honing has its limits and over time your edge is going to become dull no matter what. Therefore your knives will need to be sharpened at least several times a year. Some chefs, in fact, will use a whetstone on an almost daily basis in order to ensure their knives are always razor sharp. Most of us, however, are not professional chefs and may not even touch our kitchen knives for days at a time. In that case, it’s probably a good idea to hone the edge after every couple of uses and have your knives sharpened once a year.
Using the strength of industrial high precision superior mono-crystalline diamonds, Diamond Machining Technology (DMT) have created a durable longer-lasting flat sharpening surface that will efficiently sharpen, hone, deburr and polish almost any type of knife or cutting tool. The DMT set contains 3 one-sided whetstones that have extra-fine, fine, and coarse grits which means you have a complete sharpening system at your fingertips.
Sharp knives make the culinary world go round but finding the best knife sharpener isn’t as simple as walking into the store (do people still walk into stores?) and grabbing the first sharpener that presents itself. There are different types of electric sharpeners, some that are straightforward and some whose sharpening process involves as many as 3 or 4 stages. If you’re looking to keep things simple by using a sharpening stone well, there are 3 different types of them as well – oil, water and diamond – and they each have their pros and cons. So it can be confusing.
Different knives are sharpened differently according to grind (edge geometry) and application. For example, surgical scalpels are extremely sharp but fragile, and are generally disposed of, rather than sharpened, after use. Straight razors used for shaving must cut with minimal pressure, and thus must be very sharp with a small angle and often a hollow grind. Typically these are stropped daily or more often. Kitchen knives are less sharp, and generally cut by slicing rather than just pressing, and are steeled daily. At the other extreme, an axe for chopping wood will be less sharp still, and is primarily used to split wood by chopping, not by slicing, and may be reground but will not be sharpened daily. In general, but not always, the harder the material to be cut, the higher (duller) the angle of the edge.
These are unquestionably great starter stones. After all the sharpening done over the course of a couple days, they're still perfectly flat, showing little to no signs of wearing down. Mind you I did watch tons of how-to videos online before undergoing the endeavor, so I knew how to try to make the stone wear evenly. But, my 15 year old nephew who was working on the Ontario, as I told him he could have it, if he wanted to fix it up, didn't watch all those videos and I didn't see any uneven wear on his stone after working it about a half hour either.
If no metal is being removed from the edge of the blade, it’s considered honing. Whereas if metal is being removed from the blade edge this is considered sharpening. Certainly, even honing will result in some microscopic amounts of metal being removed from the blade edge but not enough to be visible to the human eye, so the above definition is basically a solid one.
When the stone is intended for use on a flat surface, it is called a Bench Stone. On the other hand, small, portable, hand-held stones are referred to as Pocket Stones. Also, because Pocket Stones are smaller than Bench Stones, they are more easily transported but, they also present difficulty in maintaining a consistent angle and even pressure when attempting to sharpen longer blades. Consequently, Bench Stones are commonly used at home or in camp whereas, Pocket Stones are generally reserved for honing an edge in the field.
I've been using this stone for months and have started to find that, while the fine side does provide a nice sharp edge, the 400gr side is wearing my knives unevenly, which causes me to be unable to finely sharpen the entire length of the blade when moving to the fine side. The logo that is put in the middle of the 400gr side of the knife is causing more material to be removed than the rest of the blade when I'm sweeping across. I even verified this by going straight down the length of the fine side and watching the wear pattern come from the material coming off of the knife onto the stone.
The answer to the question of how to choose a single whetstone from among the many is actually one of both purpose and expense. Indeed, as the old adage says: “You get what you pay for” – This is certainly the case with sharpening stones. In fact, as a general rule, a high quality, natural, whetstone is significantly more expensive than a man-made whetstone but, they also tend to produce a noticeably finer edge than man-made stones do. On the other hand, man-made whetstones (with the exception of diamond hones) are very affordable and, just like natural whetstones, they too are available in different grits for different stages in the sharpening process from cutting the initial edge bevel to polishing a finely honed edge.
Works well. Just got it today, sharpened two pocket knives, one a 8Cr13MoV Chinese steel, the other s30v American steel The stone made short work of both steels (which were pretty sharp already). But notably was able to make the s30v hair shaving sharp easily, something I've had trouble with. Inexpensive and useful, I love this stone. It's not the Ninja sharp 8000+ grits that you can find, but for pocket knives and EDC, it's perfect and inexpensive. Get One!!!!!!!!!!!!
I had wanted a pair of sharpening stones for a while, so was enthused to get this last week. I watched a bunch of YouTube videos on how to use them and a deburring strop I also bought and wow, my kitchen and pocket knives are now wicked sharp. Pro tip: if you post anything about it on social media, family and friends will almost surely volunteer their knives for more practice...
Diamond plates are available in various plate sizes (from credit card to bench plate size) and grades of grit. A coarser grit is used to remove larger amounts of metal more rapidly, such as when forming an edge or restoring a damaged edge. A finer grit is used to remove the scratches of larger grits and to refine an edge. There are two-sided plates with each side coated with a different grit.
