Probably, in every kitchen there is a serrated knife, because a good housewife appreciates her work. And with the help of such a blade, you can easily and thinly slice bread, vegetables, fruits, and more. Tourists and fishermen also have a serreytor in their arsenal. There are many myths that serrated knife sharpening is a big problem. So, further we will refute some misconceptions about this and consider what this knife is after all.
Serrated blade
Serreytor, or serrated blade, is a type of blade that has a wavy, sawtooth shape. Such blades with a wavy cutting edge are used to make knives or other cutting tools. A semi-serrated blade is a blade with only one part of it grooved.
The similarity of the serrator and the saw is only conditional, because the teeth of the saw are arranged with wiring on the sides and lead to the formation of sawdust. The teeth of the serratorare in the same plane. Serrated blade sharpening is usually one-sided.
A saw can be located on the butt of the knife blade - for a frightening type of melee weapons. This type of knife can often be seen in various action films, for example, Rambo used a blade with large teeth.
Pluses of serrated sharpening
For a housewife, the advantage of a serreytor is obvious, but this blade is used not only in the kitchen, but also in tourism, fishing and even parachuting. So, the advantages of serrated blade sharpening:
- Increased cutting action efficiency. The cut is made from several angles at once and improves the efficiency of cutting fibrous materials. Layered, fibrous materials such as ropes, ropes, cables, nets, etc. are not a hindrance to the serrator.
- The length of the cutting edge is increased due to the wavy line of all teeth. If we calculate the length of the blade with all the bends, we will see that it is greater than the length of the blade itself.
- Blade sharpness lasts longer due to the fact that the load is distributed evenly on all teeth and curves. Serrated sharpening prevents the blade from bending, so it lasts longer.
- Ease of penetration into the material. The sharp teeth of the serrated blade penetrate the material like a prick, cutting deeper than a simple smooth blade.
- Increases the effect of ripping penetration, which is used in defense. A serrator will cut clothes better than a blade with a smooth edge, which means that when hitting an enemy, he will literally tear apart any fabric with histeeth.
The serrator is often used as a melee weapon, not just to get thin slices of bread.
Cons of serrated sharpening
The wave-shaped blade has a number of disadvantages, consider them:
- The half serrator leaves an uneven trail. Due to the smooth and serrated blade, the knife will cut the material unevenly.
- Limited action. In some common situations, it is impossible to handle a serrated knife. For example, a can of canned food will be problematic to open.
- The serrated teeth can become clogged with sticky material.
- The cut is not as smooth as with a smooth blade. The smooth edge of the blade literally crushes the material, and the serrator tears.
- When cutting, the blade moves to the side. Due to the specific one-sided sharpening of the blade, the knife will behave differently in the hands of a right-handed or left-handed person. The longer the blade and the more force on it, the stronger the evasion.
It's important to understand what a serrator is for and not ask for more.
Sharpening
Due to the uneven surface of the serrator, it is quite problematic to sharpen the blade. The time and effort spent sharpening a smooth blade is equivalent to sharpening a single serrated ridge.
There are various inventions for sharpening serrated knives - in the form of a cone or bar. The material from which it is madegrinding tool, it can be different, for example: diamond chips, metal, ceramics and others. In order to sharpen the serrator with high quality, you must follow the following rules:
- Choose the right sharpening tool. Experts recommend a triangular grindstone, but many say it's uncomfortable.
- Determine the desired sharpening angle. Usually, experts advise to take into account the purpose of the serrated knife, but at the same time keep the sharpening angle closer to 15 degrees.
- Determining the sharpness of a blade. The smaller the sharpening angle, the sharper the blade will be. For cutting a sharp blade is not needed, you can choose a sharpening angle less.
- Properly remove burrs. As a result of sharpening the teeth of the serrator, some kind of "burrs" are formed, which can be removed with a softer sharpening tool.
If your choice is a serrated knife, first decide if you can maintain it.
