There is no doubt that knives are fundamental instruments in any kitchen in the world, be it professional or amateur. Inseparable companions of the great chefs – who display them, often as trophies -, are also great partners of the housewives who cook daily for the family.

It is important that the knife is always with its blade very sharp, so that it can fulfill its greatest function: cutting. And that’s what a knife sharpener is for, leaving the equipment always ready for cutting.

Sharpening a blade can be a simple act. There are people who sharpen it at the edge of the sink, for example, and even in ceramic mugs. But it can also be a more complex art, which requires a lot of knowledge and years of practice.

Renowned chefs argue that it is very subjective to talk about sharpening knives, as each professional uses a different type of knife. The sushiman, for example, uses thinner-bladed knives than those who work with noble meats, which require thicker blades. Each knife has a different point, a function.

The most experienced ones use stones, chairas, emery and other items to sharpen them. While many amateur cooks prefer the safety of home sharpeners. Everything will depend on the expected result and also on the value of the instrument that is being sharpened.

Therefore, in order not to risk your health or the efficiency of your knives, it is better to resort to the practicality of a sharpener, be it manual or electric. After all, nothing worse than a kitchen with cordless knives.

In a kitchen, sharpening knives is as essential as changing car engine oil in a workshop. If this process is not done, it can cause problems and wear when cooking. And having a sharpener at home can make this job a lot easier.

Gastronomy professors argue that a very sharp knife allows for a more precise cut of the food, in addition to preventing them from oxidizing and leaving dark spots on meat or some vegetables.

Blind knives can be dangerous for those who use them. They slip on the surface of the food and can cause accidents with cuts. It is also worth remembering that a cordless knife can crush food instead of cutting it, causing it to lose its juices at the time of cutting.

We have already presented in this review several advantages of having a knife sharpener at home. It makes working in the kitchen easier, as well as being practical and safe in a very necessary task in preparing food.

Other than that, their metallic discs can increase the useful life of the knives. But of course, like any product, there are still some disadvantages that we need to take into account.

Because it is a specific device, it ends up being more expensive than stones or plates. Electric sharpeners, of course, are still a little more expensive than manual ones.

Another problem is that some of the products do not sharpen all types of blades. Some of the more sensitive ones, like ceramic knives, need more specific equipment, so it is good to be attentive to the purchase, or it may end up spoiling your utensil.
