Volosin serves as a basis for a fishing tackle that connects all parts of the snap into a single whole. There are many types of fishing line: from soft to firm, different stretch marks, used for catching different types of fish. Today, this product is almost always made of artificial fibers, although sometimes there are still fluffy silk cords. But this tradition is tribute and such cords are used only a little number of anglers in the world. There are monofilament fishing lines and multi-fiber, so-called wicker cords. They differ both in production technology and in the materials from which they are made. The main materials of the monofilament are nylon, capron and fluorocarbon.
