|If you search the internet you will find hundreds of different types of knots and loops for fishing. Each one is used for a specific application, but there are only a few that you really need to be familiar with for fly fishing. At some point in your fly fishing adventure you may need to understand how to tie a Bimini Twist or Plaited Double loop, but those are not every day knots.
