Steel grade
The name of the steel grade from which the knife blade is made.
Its working properties directly depend on the type of steel — hardness, brittleness, tendency to corrosion, ability to keep sharpening, etc. Accordingly, this parameter largely determines the features of the knife as a whole. Many different grades of steel are used in modern kitchen knives; knowing the name of a particular brand, you can find detailed information about it (physical characteristics, reviews, user reviews) and evaluate the quality and overall level of the tool.
Handle material
— Plastic. Plastic is often considered a cheap and low-quality material, but this is not entirely true for kitchen knives. The fact is that the term "plastic" in this case can mean various types of polymers, often with very advanced specifications. Most often, the quality of the plastic handle directly depends on the price category of the knife. With all this, the
plastic handles are strong enough to use the knife for its intended purpose for at least several months, are easy to clean, and are also resistant to water and kitchen chemicals.
— Wood. The wood is pleasing to the eye and touch, can withstand hits and falls without any problems, and its durable varieties are not necessarily expensive. At the same time, this material is sensitive to water — it “absorbs” water, loses its presentation, resistance to cracks, chips and scratches (which is not very high anyway) and can even “bloom”, which is generally unacceptable for a kitchen appliance.
Wooden handles are not used too widely — either in the cheapest knives, where durability is not important, or vice versa, in premium-class models, where wood plays the role of an stylish material.
— Steel. This material is considered one of the most hygienic: it is easy to clean, and the design of the knife has virtually no gaps in which dirt can accumulate. In addition,
steel handles look very solid, durable and
...hard, withstand hits and falls without any problems, and are also scratch resistant. On the other hand, a steel handle is more likely to slip out of your hand than a wooden or plastic one.
— Steel with an insert. A variant designed to eliminate the main disadvantage of all-steel handles (see above) — an increased likelihood of slipping. This is what inserts are used for: they are made of rubber, plastic or other similar material that increases the "grip" of the palm with the knife handle. The presence of inserts is the only difference between handles of this type and all-steel; the rest of the features are completely identical.
— Silicone. A material that looks and feels similar to the plastic described above, but has its own specifics. The main practical difference is that silicone is much softer, some of its varieties are similar to rubber. This provides a more comfortable and secure hold in the hands; in addition, the silicone surface is often made slightly rough, which improves grip and further reduces the likelihood of slipping. On the other hand, this material is more expensive than plastic, and the advantages described are not decisive; therefore, silicone handles are not common, mainly among premium knives (although there are exceptions).Blade length
The length of a blade is usually measured from the point to the neck (the bulge between the blade and the handle). The value of this parameter is determined primarily by the type of knife. For example, in
models for cleaning, it rarely exceeds 12 cm — otherwise it would be inconvenient to work with small round products). Among
bread, on the contrary, blades shorter than 20 cm are rarely found — loaves of bread can be quite thick, which requires an appropriate knife, etc. However, knives of the same type can also vary significantly in length. In most cases, you can use this principle: a longer knife allows you to work with larger pieces of food, but it is less “agile”, and the length of the blade can affect the price.
Hardness
The hardness of the metal used in the knife blade. Indicated in standard HRC units (according to Rockwell); the higher the value, the harder the blade.
This parameter in knives has a double meaning. On the one hand, the blade must be hard enough so as not to dull prematurely, not form burrs and not deform when bent; on the other hand, it must remain soft in order to sharpen normally, not crack or break (brittleness also increases with increasing hardness). In most kitchen knives, the hardness is in the range of 52 - 62 HRC - it is believed that this range provides the optimal ratio of strength, reliability and ease of sharpening.
In general, ceteris paribus, a knife made of softer steel will have to be sharpened or adjusted more often with musat, however, such procedures themselves will take a little time and effort. Conversely, a hard blade will hold sharpening for a long time, however, you will have to try to restore it.
Country of origin
Country of origin of the brand under which the kitchen knife is presented on the market. As a rule, it is indicated by the “homeland” of the manufacturing company or by the location of its headquarters.
There are many stereotypes associated with the “nationality” of brands and products, but most of them have no basis in our time. First, the actual place of production is often different from the brand's country of origin. Secondly, the quality of a product depends not so much on geography, but on the policy of a particular company and how carefully it controls this very quality. Therefore, you should pay attention to the brand’s country of origin only if you fundamentally want or (do not want) to support a manufacturer from a certain country. Quality is best assessed by the reputation of a particular brand and the general price category. However,
Japanese kitchen knives clearly differ from other manufacturers in their quality.
Belgian and
Swiss are famous for their reputation thanks to the brands BergHoff, Vinzer and Victorinox. But
Brazilian knives also have a place in the home kitchen due to the good price-quality ratio of the Tramontina brand.
