Many buyers appreciate this hand-sharpened knife stone because it is an item that has proven useful in many kitchens. It is a model provided with two faces, one with a grain size of 1000 grit, in order to restore the blade edge so that it acts as efficiently as possible, another of 3000 grit, in order to finish everything as pleasantly as possible.

The dimensions of this article are 19 x 7 x 3.5 cm, and the non-stick base it comes with makes it very easy to use when placed on a table or other such surface. The corners are sharp, and the girls have different shades – white and brown, respectively. It must be kept in water, according to the instructions, to give the best possible results.
If you want to buy a hand-sharpened knife, this option may be right for you. Why? Because it is a stable model, easy to handle, and this is due to the fact that it is positioned on a support made of bamboo wood, which in turn is based on a silicone insert, which prevents slipping.
Regarding the granulation, it is 1000, respectively 6000 grit, the model having two faces (green and white). It will be very useful to give the shape of the knife, but also to sharpen it very well. The pottery from which this stone is made is of a high quality, which will be very difficult to wear.
This product has dimensions of 18 x 6 x 3 cm and a weight of 638 grams. It’s not the best option if you want a model that you can take with you very easily.

If you want to use this stone on a table, then you need to place a non-stick surface at the base, because otherwise it will slip and you risk getting injured.

This article is not a sharpening knife with a grinder, but it is a classic, countertop model, which comes to the aid of people who want to bring a cutting tool to the best possible shape, in order to be as efficient as possible. It’s a model with two faces, a big plus, because each has its own grain. The lighter part has 800 grit, to make the most delicate finishes, and the darkest part 240 grit, which is why it helps to sharpen and give a shape you want. It is made of natural stone.

This model has two sides – one white, which comes with a grit of 1000 grit and is suitable for finer actions and an orange, 400 grit, which will help you sharpen the blade itself.

Knife sharpening kit
Zokura, stone kit
If you are looking for opinions about the best knife sharpeners, you may come across this kit, which contains a series of very useful elements that will help you prepare the blade of a cutting tool – sharpening stone, spacers to adjust angles, smoothing stone and non-slip base box.
The main “star” of the kit is the stone, which is a model with two faces, which of course have different granulation. One is 1000 grit, being recommended to sharpen the blade, another 6000 grit, which will allow careful finishes, so that in the end everything is as fine and sharp as possible. It is made of ceramic.
The 1000 grit face is blue, the 6000 grit face is white, if you value such details. The shape is rectangular and the corners are sharp. All the elements can be stored in the box that is used as a support, in order to have them as organized as possible and always at hand.
Usually, the knife blade loses its quality and will not be as efficient. In such situations, you do not have to change the tool completely, but use a special stone to bring it to its original shape. How to choose such an accessory and what selection criteria you should follow, we will tell you below:
Granulation : This is one of the most important features when you have to buy a knife sharpener, at a good price, because this way you will realize how you will use it.
The models we find on the market with the greatest ease, have a value of up to 8000 grit and can start from 200 grit. The higher the value, the finer and faster the sharpening will be.
Keep in mind that a smaller grain is used for sharpening, and a larger one for finishing. Some models even have two faces with different grits, to use them for both actions.
Materials : Even though they are called sharpening stones, these products are often not made of natural stone . If so, then it would have a high price and many people would not afford it. There are also such options, but harder to find or more expensive. You can eventually look for a natural stone on the mountain and if you know how, sand it and bring it to the right shape to use it for such purposes.
Most of the time, these products are made ofceramic , a more affordable material that can have varying degrees of abrasion. They must be used with care, because if they get out of hand they can chip.
Dimensions : A knife sharpening stone, at a good price, is of course chosen depending on its size. The larger they are, the higher the comfort will be when you want to use the product by placing it on the table or other surfaces (for example 18 x 5 x 2.5 cm).
If you want an option that you can take with you everywhere, if you go to the mountains with a tent, fishing, barbecue or all kinds of such activities, then turn your attention to small models (for example 10 x 3 x 0.5 cm). They are also suitable for sharpening knives by holding them directly in your hand, so be very careful how you handle everything.
Appearance : Some people are also interested in what such products look like.
Here, form could matter the most. We know that when we buy a sharpening knife with a grinder, it is round. But, in the case of the classic, manual variants, it is most of the times rectangular.
There are also models in tubular shapes, with sharp edges, a kind of thicker files, which are small in size, can be taken with you anywhere and allow sharpening by holding them in your hand.
Another aspect of design is color. It is usually gray, but there are also variants that have more diverse faces, in shades of orange, blue or white or black.
Key Features : Often, small details can make the difference between a higher quality product and a weaker one. Regarding the knife sharpening stones, here are the aspects that could lead to the improvement of the experience:
Girls with different textures – if the item you bought has the same grain everywhere, it will be just as effective on all sides. But there are also variants that have two sides, on one being a lower grid value, for sharpening, and on the other higher, for finishing. Thus, with a single stone you can do everything you need.
Anti-slip sponge – it is helpful to provide stability to items that are used on the worktop, not in the hand, so that it does not slip during use.
Rounded corners – are present on models that will be very comfortable to hold in your hand. They will not hurt you if you catch them too tightly and there is no danger of being stung in the corners which can be very sharp.
Use without water / oil – most of the time, these sharpening stones must be kept in water 10 minutes before use or greased with oil. If you do not like such an idea, then you will have to take a larger amount of money out of your pocket, because the options that do not require such actions are usually much more expensive.
Now that you have learned how to choose the best knife sharpening stones, all you have to do is go to the online stores and make the desired purchase. There is nothing very difficult, and the product will come into your possession as soon as possible.
How to sharpen knives correctly depending on the material and type
Many people ask this question and try to find the best answer to it. In practice, what you need to know about the materials that can be sharpened with a stone.
For example, you can act whenever you need on cutting accessories made of carbon steel, stainless steel or other types of metals, but you will not have to sharpen variants made of ceramic.
Regarding how to sharpen a certain knife depending on its type, you may not find information for absolutely any model. And you wouldn’t even need it. Why? Because a number of general rules apply.
First of all, you have to prepare the stone with which you will do the work. It must be kept in water for 10-15 minutes, to cool the knife blade during sharpening, because it will get very hot. You can also use oil if you want, but don’t forget that since you used this liquid once, you only have to use it once.
When you actually go sharp, go with the blade over the stone keeping it at an angle of about 20 degrees. With one hand hold the handle of the knife to form the required angle, with the other press on the top of the blade. Do this a few times, until you see that you reach the desired result. If you use a stone with two faces, first work with the more abrasive part, for sharpening, then with the fine one, for finishing.
If you have a knife with a more strange shape, then a small stone or a massage could help you, which will penetrate even the most difficult to reach angles, as happens in the case of curved ones.
Finally, we want to tell you a little more about how most knife sharpening stones work (at good prices). The results may not be the ones you want at first. And this is normal. Why? Because 4-5 sharpening will have to be done until the stone makes its “run-in”.
At the same time, you should also know that in time, on the surface of this accessory it can be formed as a kind of depression, this happening because the middle area is used more. To keep the stone in very good condition, after 4-5 uses, use another similar product to level it. You simply take both elements and rub them together.
