How To Choose A Good Knife
The knife is an important tool that facilitates our daily lives, but we especially appreciate its importance when we are in nature. However, choosing a good knife, especially one that doesn't cost too much, is a difficult task. However, if one knows exactly what they are looking for, they can find a good knife for a very decent amount. Here are some tips that can help you in your search, especially if you are not a lit knife:
1. Fixed blade or folding knife?
What do you want to do with the knife? For example, will you need to cut and trim wood or to open packages and cut a rope or fabric? Generally, for heavier tasks, such as playing game or wood, it is much more convenient and safe to use a fixed-edged knife. While for lighter tasks such as opening packages or preparing food, a folding knife can easily be used. The main difference between the two types is that the folding knife is usually much lighter and more compact to carry, but does not offer the same blade stability under heavier loading.
With folding knives you have two types of opening. To open the classic folding knives, it is necessary to use both hands. Modern tactical folding blades have a quick-opening mechanism that allows the blade to be pulled out quickly with just one hand. Which one you need depends on what you use the knife for. With fixed-blade blades, the belt is important - what material it is, how strong it is, what wearing it allows. For example, in addition to classic canoes, there are neck-wear canisters that facilitate concealed carry, even canoes that allow attachment to tactical modular systems.
2. What will you cut with the knife?
The difference between using a knife to cut food, to process wood, to scrape, to cut ropes or to open packages is essential. Different tasks set different requirements for the blade. There are basically three determining factors for how well one cuts a blade - the shape of the blade, the heat treatment and the type of steel. Heat treatment of steel is a complicated process, but any modern knife, even if it is of a low grade, has a pretty decent heat treatment. The type of steel is also an extensive topic, to which we will dedicate a separate article, but briefly we will turn a little further into the text. Particularly important for the knife is its blade shape. It is determined by profile and bevel.
Generally, the shape of the blade depends on what kind of work is intended. If you are going to cut thick ropes or nets, a "hawk beak" or a curved back blade will be helpful. For more specific tasks, such as those of the rescue services, for example, when it has to be cut, but care must be taken not to puncture anything, there are blades with a blunt tip or a sheep's foot. Practitioners of martial arts usually resort to a tanto-type blade because of its puncture or warncliffe-type cutting. In general, hunters rely on the so-called. "drop point" blades or curved blades (used for milling).
If you need a knife for general use, the choice is usually to fall back, drop point, clip point or blade. No matter the name, you should look for a knife with a sharp, sharp tip, a nice, smooth curve (called the "belly" on the blade, this is the part you will most use) and a straight part near the handle. If you have no experience with sharpening, it is better not to take a very curved blade.
3. How will you use the knife?
The work for which the knife is intended determines both the profile and the bevel (sharpening) of the Blades. Bevelling is the method used to create the blade. There are at least a dozen types of bevel, but three are the most common - concave, flat, and convex.
If we imagine the blade as an inverted triangle, with the concave bevel (A), the sides of the triangle are curved inwards. This allows the thick steel to be quickly reduced to a very sharp edge. This sharpener is good for cutting. The flat bevel (B) of the sides of the triangle are straight. This bevel is good for general felling and performs well when loaded, and the edge is shock resistant. With the convex bevel (B), as the name implies, the sides of the triangle are curved outwards. This adds great strength to the blade and the cutting edge. This type of sharpening is very suitable for hard work. Used in cutting tools such as machetes, hammers, bows and camp knives.
Two specific types of sharpening can be mentioned here. Sharpened (toothed) sharpening is very useful when cutting fibrous material such as a rope or net. But if you use the knife often, you will have to sharpen it often, and with serrated blades, it is more difficult. Scandinavians are common in nature knives. If the other bevels have a large bevel (the main one) and a second bevel, just at the end that creates the cutting edge, then the second bevel is missing in the scandy bevel. This makes the blade very sharp and suitable for use in nature, but also difficult to sharpen properly. If you have no experience with sharpening, it is better to opt for a different bevel.
4. What kind of steel is a knife?
There are three main indicators regarding steel selection - corrosion resistance, hardness and strength. The balance between the three that will be right for you again depends on the tasks for which the blade will be used.
The corrosion resistance determines how much the steel lends itself to rust and discoloration. Not only water can oxidize steel. Acidic foods such as tomatoes can also oxidize the blade. There are some steels that are very resistant to corrosion, such as Krupp 1.4116 (Victorinox Swiss Knife Steel), VG10 and N690. There are extremely durable stainless steels like H1. In general, the more corrosion-resistant the steel, the less the strength or rigidity of both, or both.
Hardness is related to the ability of the steel to absorb the load without deforming it. The advantage of harder steels is that it imparts resistance to the blade and also gives it greater sharpness and, accordingly, better cutting ability.
Strength is the ability of the steel to absorb, without damaging, saturate, crack, etc. It is important when the blade performs tasks such as cutting a tree, when there is a strong collision.
We will elaborate on the steels and their other characteristics in the following materials.
As a conclusion,
you could say that finding a good knife is a challenge. But when one knows exactly what to use it for and how intensively they will need to work with it, one can better navigate among the different classes and prices to find the best for it, the most acceptable price.
