Types of devices for sharpening knives

Sharpening devices knives can be classified according to the following indicators:

Bars and whetstones

A whetstone (whetstone) is an abrasive tool used to sharpen the cutting edges of household appliances and kitchen utensils, carpentry and metalwork tools.

The industry produces four types of stones for sharpening knives:

The type of bar used, as well as its size and grain size, are selected by the user independently, in accordance with the need for the quality of the processing performed

Hand tools       

This category includes manual machines for sharpening knives, as well as musat.

Musat is a rod made of various materials, equipped with a handle and characterized by a rough drawing of the working surface.

Musats differ in geometric shape and types of materials used in the manufacture

The roughness of the drawing is the size of the notch applied to the rod, and it is this that determines the degree of roughness of the cutting surface of the knife after its processing. Musat is equipped with a rod that has a certain degree of magnetization, which ensures that metal particles formed during use get into food and kitchen utensils. Musats are classified by:

The action of the abrasive tool on the cutting surface is carried out using the forces applied by the user. The main task performed by the manual machine is to create and maintain the optimal angle of sharpening of the cutting edges for the entire period of work, which is achieved by rigidly fixing the knife in a given plane. The industry produces various models of such equipment, differing in the size and method of attaching abrasives and processed knives, as well as the materials used and cost.

Manual machine model "Chefs Choice 415"

Manual knife sharpeners can be used not only as household equipment, they are successfully used by professionals as well. The only difference between models for household and professional use is their cost, which depends on the type of abrasive materials that guarantee the quality and speed of sharpening.

Professional and household knife sharpeners equipped with an electric drive

The presence of an electric drive greatly simplifies the process of using devices for sharpening knives, this applies to both models for home use and professional use.

Distinctive features of models for various types of use are:

Electric sharpener "Chefs Choice" model "CH / 220" for universal use

Household electric sharpeners do not take up much space and are very functional, because in their design, as a rule, various fixed sharpening angles are provided for different types of knives and other cutting tools (scissors, screwdrivers, etc.). The ability to quickly and efficiently sharpen the cutting edges of knives is very important for catering establishments, where the speed and quality of cooking depends on sharpening. Professional machines for sharpening knives are functional devices equipped with high-quality abrasive tools that allow you to perform not only rough sharpening, but also fine-tuning the cutting edges of knives for various purposes.

Sharpening angles, descents and micro-leads - on the cut of the knife blade

This value is for:

Some types of knives are sharpened with other sharpening angles, such as those intended for slicing bread (the angle is 15˚), but this is a narrowly targeted use, in which sharpening must be performed quite often, because with a decrease in this indicator, the resistance of the cutting edges decreases.
