Non-Slip (Kreh) Loop Knot

The non-slip loop knot or non-slip mono loop is also known by the names Kreh loop knot and Lefty Kreh’s loop knot since the fishing legend Lefty Kreh popularized it. As it doesn’t grip the lure or fly, it forms a flexible attachment giving it free, natural movement. It can be tied in monofilament, fluorocarbon as well as braided leaders.

How Do You Tie a Non-Slip Loop Knot


  1. The size of the loop needs to be adjusted while the turns around the standing part are still loose. Once it is tightened, the loop size cannot be altered.
  2. The number of turns made in step 2 depends on the strength of your fishing line. If it is six to eight pounds you should make around seven turns and if it is 60 pounds or more then around two turns should suffice.



  • Very strong
  • Does not slip
  • Retains most of the line’s strength
  • Since the tag end faces the hook, the knot doesn’t catch grass and weed while retrieving the line
  • Being more obtrusive than other knots, it may not be suitable for fish that are line-shy
  • Fails to be your go-to knot when you don’t want your lure to swing freely on the line, like, when you need to manipulate your plug
