How to tie the most popular loop knots in fishing. Use the Perfection Loop to tie a nice compact and reliable loop at the end of a fishing line. The Surgeons End Loop is easier to tie and is considered totally reliable but makes a knot that is just a little bulkier and the loop lays a little off center. The Dropper Loop makes a loop anywhere in the middle of the line which is useful for attaching hooks or other tackle.
Here also we have the Kreh Loop and the Non Slip Loop Knot which are the same knot by different names. The Rapala Knot is very similar and they all are used for tying a lure or fly to a line so that it can move freely in the water.
