1. Stopper Knots

2. Overhand knot • Thumb method - create a loop and push the working endthrough the loop with your thumb. • Overhand method - create a bight, by twisting the hand over at the wrist and sticking your hand in the hole, pinch the working end with your fingers and pull through the loop.

3. Double overhand knot • The double overhand knot is simply a logical extension of the regular overhand knot made with one additional pass. The result is slightly larger and more difficult to untie. It forms the first part of the Surgeon's knot and both sides of a Double fisherman's knot. The Strangle knot is a rearranged Double overhand knot made around an object. It is sometimes used to secure items to posts

4. Figure-eight know • The figure-eight knot is a type of knot. It is very important in both sailing and rock climbing as a method of stopping ropes from running out of retaining devices. Unlike the overhand knot, which will bind iron-hard under strain, often requiring the rope to be cut, the figure of eight can be easily untied after even the greatest strain

5. Stevedore Knot • The Stevedore knot is a stopper knot often tied near the end of a rope. It is more bulky and less prone to jamming than the closely related figure-of-eight knot.

6. Oysterman's stopper • Ashley's stopper knot, also known as the Oysterman's stopper, is a knot developed by Clifford W. Ashley around 1910. It makes a well-balanced trefoil-faced stopper at the end of the rope, giving greater resistance to pulling through an opening than other common stoppers. Essentially, the knot is a common Overhand noose, but with the end of the rope passing through the noose eye, which closes upon it. • Ashley developed this knot in trying to duplicate a knot he saw on a boat in a local oyster fishing fleet. When he had a chance to observe the knot up close at a later time he realized it was just a badly water-swollen figure eight stopper knot
