This type of cutting tool, such as a circular knife, is widely used for cutting leather, paper, rubber, polyethylene, plastic, all kinds of fabrics, cardboard and some other materials. The main feature of such a knife is that, unlike an ordinary model tool, the ability to crush the material and, accordingly, produce an uneven cut, is nullified. It should also be noted that often roller knives are sharper than scissors. Another important feature of this fixtures consists in the absence of the need to sharpen its cutting surface (it is enough to simply purchase inexpensive interchangeable blades). Note that in the kit for the presented product of such blades is 5 pieces.
The cutting tool itself, the length of which is 180 mm, is made of high-quality plastic, which greatly facilitates the design and, of course, is an important factor, since often when working, the knife has to be kept on weight. The sharpened blade made of high-carbon stainless steel with a diameter of 45 mm is closed by a plastic casing and is extended by pressing the lever built into the handle. A safer tool is the presence on the handle of a safety button that prevents accidentally pressing the lever.
We point out that in order to extend the life of the blades and protect the surface of the desktop, it is recommended to use such a knife on a special cutting mat. A variant of such a rug is also presented on this site.
Thus, a circular knife is able to greatly facilitate the life of lovers of modeling and creating all kinds of homemade, and due to the low price and fairly good workmanship, such a device will be an excellent acquisition for you.
