19 key What does the 28 key of fishing rod mean?

Tonality of fishing rod. The so-called tonality of fishing rod actually refers to the hardness of fishing rod body. For traditional fishing rods, the easiest way to distinguish tonality is to divide the fishing rod into 10 segments, hold the rod horizontally, and locate the tangent point of the arc formed by the natural bending of the rod body, which is the basis for judging tonality.

For example, the tangent point of the last arc is a superhard tuning stick, also called 1.9 tonality; The first two paragraphs are hard tuning, also called 2.8 tonality, and the first three paragraphs are middle tuning, also called 3.7 tonality; The first four paragraphs are soft tonality poles, also called 4.6 tonality.
