The benefits of technological progress make life easier for everyone. This is its main charm. Not so long ago, people could not even imagine those things without which they cannot live today even a day. As a simple example, we can give everyone the well-known scissors. A very successful and still in demand invention, I must say.
Many, engaged in cutting fabrics, and in general sewing, still use scissors as the main tool. But what if they could find a replacement? Replacement in the form of a circular knife. We will tell you about the main and most significant advantages of this new-fangled tool in this short article, and it is up to you to decide whether to try it in practice.
Device
In their design, circular knives are not much different from their older brothers. Their main elements are still the handle and blade. On some models, there are even special sub-finger recesses on the handle or a full stop that prevents fingers from slipping onto the blade.
In most cases, the handle of a circular cutting knife is made of plastic, so as not to burden the tool. It can be straight or have an ergonomically curved shape. A common element of the handle is a safety mechanism. Its execution may be different, but its main purpose is to protect you by extending the protective cover if it is movable, or by drowning the blade in the handle until the cover, if fixed, completely covers it.
As the name implies, the blade of the circular knife itself is represented by a round plate sharpened around the circumference. In the center there is a hole for mounting the blade on the axis of the handle. The blades also come in different sizes, which adds to the versatility of the tool, because a smaller diameter blade is much more convenient to perform small jobs that require precision.
Features
Roller knives, like any other equipment for sewing production, have a number of features that need to be considered. We advise you to familiarize yourself with them:
- A roller knife does not crumple matter or leather, like a regular model tool.
- Quietly deals with cutting through coarse and dense tissue or skin. Including with several layers at the same time.
- Roller knives are often sharper than scissors.
- They do not need to be sharpened. It is enough to buy an inexpensive set of interchangeable blades.
- Operating with a circular knife is much simpler and less labor intensive.
disadvantages
Alas, there are no perfect tools. Everything has weaknesses. In this case, it is:
- Inability to cut shapes with intersecting lines. Cut, for example, a triangle, while not extending beyond the laid one of the lines, it will be very difficult.
- Over time, a backlash may appear in the knife, due to which the quality of the cut will suffer.
- A circular knife should only be used on the surface of a special mat. Otherwise, the blades will quickly deteriorate.
As you can see, a circular cutting knife is a very useful tool for any seamstress. Although it has minor disadvantages, the advantages, in our humble opinion, still outweigh.
