  • Slide 5
  • Whipping is a good start if you want to learn about knotting. Use a thick thread, with different colors at each end of the rope. We use in making the carrying the rope very easily. Normally used to secure an eye splice or to protect the bitter end of a rope from chafe. Used to protect the end of a rope from chafe. Can only be used on stranded rope.
  • Slide 6
  • It is used to join two dry ropes of the same thickness. It will not slip, and can be easily untied when wanted. Do not confuse it with the "Granny" knot. It is the only knot used in First Aid work.
  • Slide 7
  • Used to tie on the poles. Is a very strong knot. Can be used in dragging fire woods during camping. There are of two kinds full timber hitch and half timber hitch.
  • Slide 8
  • Use to attach a rope to a pole, this knot provide a quick and secure result. It rarely jams, and can in fact suffer from the hitch unrolling under tension if the pole can turn. Often used to start and finish lashings. With practice, this can be easily tied with one hand - especially useful for sailors! A knot that is easy to make. Usable when you want to moor a boat. Do not use to tie something to a square post as it can easily come off.
  • Slide 9
  • FFor stiff ropes and cords you shall use the Fisherman's Knot. YYou should make it double on cords of nylon, or it will not last. TThe fisherman's knot is used by fishermen to tie silkworm gut together. I tt is easily untied by pulling the two short ends, but it never slips.
  • Slide 10
  • The Sheetbend is a knot that you use to tie two ropes together. Good both for thick and thin ropes. Easy to untie. Use the Sheet bend (Becket Hitch) when you hoist a flag, and the loop already exist.
  • Slide 11
  • The Sheepshank is a shortening knot, which enables a rope to be shortened non-destructively. It is sometimes necessary to shorten a rope temporarily and not desirable to cut it, and the sheep-shank knot solves the problem. It is used by the sailors, who do not believe in cutting ropes. It will stand a tremendous strain without slipping, but will loosen when held slack, and can be untied by a quick jerk of the two outside ropes forming the bights. Tip. Never cut ropes to shorten them!
  • Slide 12
  • The bowline, a loop that will not slip, to tie round a person lowered from a building, etc. Fixed loop, very safe. You can use it when climbing and lifesaving etc. If your life depends on this knot, you should do an extra knot to make it safer. Often learnt by thinking of the end as a rabbit, and the loop as its hole, and as Elma Fudd would say: The rabbit grows up, out of his hole, wound the back of the tree, and back down into his burrow!
  • Slide 13
  • The Thief knot resembles the Reef knot at a casual glance.Reef knot Note that the ends of the Thief Knot come off opposite sides of the knot. In the Reef knot, they come off the same sides. However, the Thief knot has no strength whatsoever, and will slip under tension. Tip. Only use this knot for tricks. NEVER use it where life and limb are at risk.
  • Slide 14
  • This is the simplest knot of all. It is commonly use to temporarily "stop" the end of a fraying rope. The overhand knot is commonly tied in a bight formed at the end of a rope, forming the Overhand Loop.
