  • How to sharpen a knife with a grinding wheel
  • How to sharpen a knife with stone
  • How to sharpen a knife with a steel

It's possiblesharpen a knife with the grinding wheel, with the sharpening stone or with the steel cylinder. Let's start with the most difficult undertaking which involves the use of the electric grinding wheel, the one also used byknife grinder.

How to sharpen a knife with a grinding wheel

The method not recommended involves the use ofgrindstone electric. The electric grinding wheel is likely to ruinthe cutting edge.Just a little pressure error and the damage is done. If you are a beginner, practice with scissors blades or old knives. The principle is the same as the "stone", ie the blade must maintain a fixed angle of 20 ° with respect to the surface of the grinding wheel.

With stone it is easier to maintain the angle as the stone is straight and the sharpening is manual. The grinding wheel has a rounded surface and the motion is electric, so there is less control.

How to sharpen a knife with stone

With the'sharpeningwe're going torealign the cutting edge. The so-calledwater stoneis a good ally forsharpen the knife blades, both for cooking and hunting.

The secret is to keep a fixed angle so as to offer oneuniform sandingalong the entire edge of the knife.

On the market there are sharpening kits with water stone that provide different grain. How are they used? First of all:

  1. Soak the stone in water for 10 minutes.
  2. Grab the knife by the handle and, maintaining an angle between 15 - 17 ° (just below 20 °), pass the blade over the surface of the stone.
  3. Turn the knife and repeat the operation on the opposite side.

The same operation will then be repeated on the finer-grained stone (the less rough one). Somesharpening kitthey also have a sort of “plastic guide” that will allow you tosharpen knivesmaintaining the correct angle.

The kits sharpen knivesthey are not very expensive, among many others, I would like to point out one with a non-slip bamboo base and guide corner, offered on Amazon at a price of 25.99 euros. For all information, I refer you tothis Amazon page.

Note: the non-slip base is not necessary, if the kit you choose does not have a non-slip base, place the stones on a kitchen towel to keep them in place.

How to sharpen knives with steel sharpens knives

Forsharpen a knife without a stone, it is possible to use the steel cylinder. This is the most used tool for sharpening kitchen knives, the classic movement goes from the base of the knife to the tip.

Practice about 10 "strokes" on each side of the blade. Each stroke must accompany the knife from bottom to top, from base to tip.

The steel cylinder is also recommended in case ofceramic knives, but only if of excellent quality.

The steel knife sharpener is the favorite tool of butchers because it is very practical and allows you to realign the edge of the blade in a few seconds.

Also in this case, for completeness, I refer you to an Amazon product, this time tested, with full satisfaction, in first person. It is a 31 cm knife sharpener (with a long shaft, slightly flattened, therefore easier to use even for beginners) offered by Amazon at a price of 19.40 euros with free shipping. For all information on the product, I refer you tothis Amazon page.

If the stone may be more suitable for sharpening hunting knives that require precision, the steel knife sharpener cylinder, due to its practicality, is designed for daily use.

Please note:
also on Amazon there is no shortage of grinding wheels for knives and electric sharpeners with about 300 revolutions per minute ... but, once again, I do not recommend their use!
