The Kreh Loop, also known as the Non-Slip Mono Knot, is a very strong loop knot that has a tag end hitched around the standing line. It was originally developed by Lefty Kreh when he was trying to create a strong loop knot. The purpose of this knot is to end up with a strong fixed loop in the end of the line that allows for easy movement because it will not grip the lure. It is recommended to adjust the size of the loop when the turns are loose because once it is tightened, the size of the loop will be fixed. The number of turns that you will need to make on your line will vary depending on the strength of your line. For example, if your line is six to eight pounds you should make about seven turns and if your line is 60 pounds or more then your should probably go with two turns.
