世界上唯一不变的就是“变”,钓线的线径也是如此。早在许多年前,国外的钓鱼人发明了飞蝇钓法。为了提高拟饵的隐蔽性,需要绑拟饵的引导线径尽可能的细。但是如果整条线采用细线径,其强力得不到保证,如果选用粗线径,又达不到使用要求。为解决这个问题,在当时的生产条件尚不完善 The only constant in the world is “change”, as is the diameter of fishing lines. As early as many years ago, foreign fishing people invented the fly fishing method. In order to improve the concealment of the proposed bait, it is necessary to tie the bait guide wire diameter as fine as possible. However, if the entire line with thin wire diameter, its strength can not be guaranteed, if the use of thick wire diameter, but also reach the use requirements. In order to solve this problem, the production conditions at that time were not perfect
