All knives are different from each other, not only because the manufacturer tries to make each model original and memorable. In many ways, the shape and dimensions of the knife are determined precisely by its purpose and scope.
That is why, in some ways, elegant fillet knives with a long and narrow blade. Are not suitable for hiking and working with small branches, and tourist models do not allow you to easily cut some types of products.
To date, all knives have a certain type of sharpening, so they are perfect for performing a particular job.
Smooth sharpening (aka, straight or flat from the English. Plain) is found in most knives with a fixed or folding blade and is the most familiar for many users. Moreover, this type of sharpening has been used in knives since time immemorial. As ease of execution and maintenance is complemented by good versatility. Making such knives suitable for a wide range of tasks.
The advantages of a smooth sharpening of the cutting edge also include high efficiency. When working with soft materials in the case of a small sharpening angle. And ease when working with hard materials with a small sharpening angle.
The disadvantage is that knives with a smooth sharpening are not suitable for working. With fibrous materials and when cutting. For example, rope, such a knife will become dull rather quickly.
To sharpen a blade with a smooth cutting edge, even the simplest whetstone will often be enough. Which makes it easy to maintain such knives in the field.
Serrated sharpening, both in appearance and in the principle of operation, is similar to a saw. Most often, such a cutting edge is a set of sharpened teeth of the same or different shapes. Thanks to this shape, it is possible to increase the area of the cutting edge without changing the length of the blade. Which has a positive effect on the cutting efficiency.
The advantages of such sharpening are high efficiency, especially when working with fibrous materials, and excellent wear resistance. As a rule, serrated sharpening stays sharp longer than smooth.
Alas, this type of sharpening has its drawbacks. For example, knives with such a sharpening of the cutting edge are not suitable for working. With fabrics, they tear them and are not able to provide a smooth and accurate cut. In addition, to sharpen a serreytor, you need to use special whetstones. Which are sometimes difficult to find even in urban conditions. Not to mention the cases of editing such a blade on a hike.
Semi-serrated sharpening, it is also combined – an excellent choice for a universal camping knife. This type of cutting edge is characterized by the presence of both smooth and serrated sharpening.
At the same time, most often a smooth sharpening extends from the tip of the blade. And approximately to the “center” of the cutting edge, and then, to the very base of the blade, a serrated one. With such a knife, you can both cut food and cut a rope or slings.
The advantage of the above sharpening is its high versatility and ability. To work effectively with different types of materials.
