Transcript of Knots and knot tying
Knots AndKnot TyingFor Search &Rescue
• Knots used by rescuers are divided into 4 classes: – Class I—joining knots, – Class II—anchor knots, – Class III—middle rope knots, and – Class IV—special knots.
• The variety of knots, bends, bights, and hitches is almost endless. These classes of knots are intended only as a general guide since some of the knots discussed may be appropriate in more than one class. The skill of knot tying can easily be forgotten if not used and practiced. With experience and practice, knot tying becomes instinctive and helps the rescuer in many situations.
