The method of reinforcing and tying the hook for large objects is very simple. First, one end of the fishing line is folded back five to ten centimeters and placed at the hook bend, and then the line with one end folded back is wound back five to seven times on the hook handle. Thread the end of the return line through the hook loop, tighten the loop from one end of the long line, and finally cut off the end of the line. Large fish hooks are usually used to catch herring. There are two kinds of hooks: barbed and non-barbed. Its hook bar is thick, the hook handle is short, the hook door is wide and the hook tip is turned inward.
