Remove any twist from legs. Select a swivel with adequate wire diameter. Too small a swivel will actually cut the knot. Pull loop through swivel 2. Rotate vertically through loop three times.
Saliva helps lubricate the knot.
Pull against line, making sure legs of the double are equal length. Use thumbnail to cinch down tight. Carefully measure doubled line to a maximum I.G.F.A. allowance of 15' overall in line classes 5 - 50 and 30' for line classes 80 and 130. Plait tightly, so knot never creeps or slips. To end knot, form loop with loose end and continue to plait.
