The Kreh Loop Knot (also known as the non-slip loop knot) is a strong, popular fishing knot developed by Lefty Kreh that creates a secure, open loop at the end of a line. It allows lures, streamers, and flies to move freely, enhancing natural action in both freshwater and saltwater fishing.
The Kreh knot (or Non-Slip Loop Knot) disadvantages include potential strength loss if tied incorrectly, visual bulkiness compared to other knots, and a tendency for the loop to become worn or misshapen under heavy strain, particularly with stiff fluorocarbon or heavy tackle. It is also less ideal for situations needing limited lure action.
