How many swivels should be used when fishing? Generally, the fewer the better; every swivel requires a join either to the line or cast, which weakens it. On most occasions just | one is enough, provided that is has been properly maintained and is us-. ed with an efficient anti-kink vane. But there are arguable exceptions to this rule. Some would say that the choice depends upon the length of the trace: a short trace needing two swivels, one at each end, while a longer trace needs another built in about the mid-point. In eel-fishing, too, multiple swivels are necessary. Eels have the habit of spinning in the water, causing severe line twist. Because they also have sharp teeth, it is advisable to make up a number of short fine wire traces, with the hook at one end and a swivel at the other. If you slip a ledger weight on to the reel line before tying the hook link on, the swivel acts as the stop and prevents the lead slipping down to the hook. 3 Anti-kink devices 3 Anti-kink devices either attach to the line in the form of a vane, which is designed to hold it and prevent it iturning, or by means of a weight iclipped to the line and intended to zhold it from revolving. Celluloid or plastic vanes fastened to the line work well in principle, but wear slightly after repeated use, allowing the line to turn after all. An improvement is the Kneverkink, a finned tube that fits on to the line and slides on to one eye of the swivel, holding it and making sure that the other parts turn. Last, and probably best of all, is the anti-kink vane designed specifically to complement the ball-bearing swivel, clipping on to its barrel and really making sure that it remains stationary.
