Ever wonder how to tie the rapala fishing knot? Wonder no more. Watch this instrucional knot tying video and find out. The rapala knot is a popular method to tie a lure (such as a rapala!) to a line such that it can move freely and unimpeded by the knot. Essentially the same as the non slip mono loop, the knot has one more step in it's making. Whether this makes it more secure is still up to debate. It does make it slightly more difficult to tighten down neatly, but with practice it can be done. You should know how to tie one or the other for the occasions that you want your bait to swim more naturally.
