Best chopping knives for 2020

A construction knife is useful for any craftsman or installer. Thanks to it, it becomes easier to perform simple operations, for example, cutting cardboard, plastic or similar materials. If you buy a high-quality product, then it can last over one year. In addition, it is important to understand that in this case, the cost is not the standard of the guarantee. Even expensive devices can fail after a single use. And to make it easier to choose a product, the editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best assembly knives for 2020.

Selection features and main elements

The main part of such equipment is the body. It can be metal or plastic. The peculiarity of the first option is its low price, compactness and ergonomics. Metal products are distinguished by good shock resistance and reliability, but due to the heavy structure, it is not always convenient to work with such a model.

Construction knives resemble office supplies, but there is one significant difference - the presence of a guiding element, which is located in the body. Thanks to this element, the blade can be fixed in one position. Therefore, it will not cut into the body when working with dense materials. Also, this product allows you to hold the tool with a finger, which significantly increases cutting accuracy and increases safety.

The second thing to remember is the thickness of the guide and the backlash relative to this element. If the blade stroke is high, then the product is not doing its job and the manufacturer has supplemented it as decorative purposes. It is better to give preference to a reliable and durable option that will last several years and will not deteriorate.

Modern solutions

Today there are two popular versions of cutting knives:

• Mechanical;
• Automatic.

The latter option has an automatic blade feed system. This solution allows you to replace the blade with the push of a button. In addition, most knives are equipped with a special compartment that holds 2 to 4 blades. This has a positive effect on the mobility of the instrument and makes it possible to use it in all situations.

Another feature of construction products is that they do not require sharpening. Almost every model uses segmented blades that break off easily as they wear out. Such designs can be updated 7-13 times, depending on the number of segments. Trapezoidal models are also sold, but they are only intended for cutting dense materials such as linoleum or carpet. Breaking off the blade, in this case, will only work twice.

What is important to know when choosing steel

The knife is selected not only based on convenience and strength, but also on the cutting ability. Three types of steel are traditionally used:

• Tool steel. There is a CS marking.This option is not very reliable, therefore it is only suitable for working with materials such as cardboard or paper. Also cuts wallpaper well. However, before work, you need to stock up on blades, as they break the fastest.
• SK This is a more robust option and is intended for cutting plywood or linoleum. Such a performance is called professional steel.
• But there is also a better performance. Marked as SK This material is used exclusively in expensive structures.

To prevent corrosion of the main elements, burnishing is carried out during the production phase. This prevents this process from spreading. It is easy to find such designs, since the blade has a rich black color. Most often, they are found at the Russian company VIRA.

What is important to know about the fixing element

Intermediate fixation takes place in several ways, it all depends on the type of specific performance: automatic, twisting and push. The most popular option is the automatic type of retainer, since when working with such a knife, a person does not need to perform any action, which will not be distracted from the process. However, professionals recommend using products that twist, this ensures high reliability. The push-button options are a balanced option and provide convenience with high reliability.

It is important to understand that experienced builders have a collection of their favorite knives that suit a variety of tasks. If a person buys a product for the first time, then it will not be possible to immediately find a suitable model, it is necessary to try different designs in order to understand which fixing element is most convenient. Also, we must not forget about the handle, it should sit well in the hand and not slip.

What to look for when choosing?

In order for the product to serve the maximum period, you need to know in advance what technical characteristics are best to pay attention to. Thanks to them, a person will select the optimal configuration that will cope with their work by 5 points:

• Retractable mechanism. Most of the problems are associated only with this element. The device should work quickly and conveniently. No delays are allowed. Because with a complex technical process, it can cost a positive result.
• Helper functions are needed only for those who do not use this product often. When a person cuts several dozen different materials every day, additional options are replaced by convenience.
• The weight of the structure must be balanced. Of course, the lighter the product, the better, but we must not forget that this also affects strength.

The plastic slider can be used, but only the one that looks good. If a flimsy design is applied, even an inexperienced person will notice it. It is not recommended to buy such a product, as it will break after a single use. If you press such a knife, the mechanism will stop functioning and the blade will not be able to be fixed in one position.

There are also knives with a plastic wheel. They provide good grip and reliability. However, it is important to understand that if you firmly clamp the blade, then there is a possibility that the person will not be able to unscrew it after that. Therefore, the knife can be thrown away immediately.

One of the best options is a metal wheel. It is easy to operate and provides high reliability in all situations. It is desirable that the knife is also made of metal. But even here you can buy a low-quality product, for example, some manufacturers sell a product made of mild steel. The best solution is a knife made of stainless material.

For frequent use, a model is suitable, which has replaceable cutting parts, the size of which is 25 mm. The main feature of this design is high strength and reliability. In addition, this option is suitable for most types of work.Blades for a mounting knife do not differ in such characteristics, mainly manufacturers produce models with a width of only 18 mm. This solution only handles small tasks well.
