2  Definition  Types  Different types of knots  Uses  Demonstration  conclusion

3  Rope: it is a very strong thick string made by twisting thinner strings, wires, etc. together.  Knot: it is a join made by tying together two pieces or ends of string, rope, etc. (oxford Advanced Learner’s Dictionary, 2005) Advantages:  Portable  Cheap  Easy to make the knots  Very strong  Easily available

4 1. Whipping. 2. Reef knot. 3. Timber hitch. 4. Clove hitch. 5. Fishermen’s knot. 6. Sheet bend. 7. Sheep shank. 8. Bowline. 9. Thief hitch. 10. Thumb knot

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.

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.

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.

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.

9 FFor stiff ropes and cords you shall use the Fisherman's Knot. YYou should make it double on cords of nylon, or it will not last. TThe fisherman's knot is used by fishermen to tie silkworm gut together. I tt is easily untied by pulling the two short ends, but it never slips.

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.

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!

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!

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.

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.
