STEP 1 Lay two ropes parallel to each other and tie a Double Overhand
Knot (see Chapter 1) on each of the two sides.

STEP 2 Tighten up each Double Overhand Knot and pull the two ropes
apart so that they form a circle, further tightening the knots.

This bend provides more security than the Fisherman’s Knot, which
you may need if you use very slippery lines or they differ in size a bit. If
you need more security than that, you may consider using Triple

Overhand Knots (see Chapter 1) to fasten the two ropes. If more than a
Triple is to be used in fishing line, it should be tied in the same manner
as the Uni-Knot (see further).

IMPROVED CLINCH KNOT

This knot is a useful fishing knot that works well with thin

monofilament.

STEP 1 Pass the running end through the hook eye or other attachment
point, then make three to five wraps around the standing part.
