The Rapala Knot is the knot that the Rapala brothers recommend to use with Rapala lures. The Rapala Knot attaches the lure with a loop at the end of the line. The loop will allow the lure to move freely and naturally. The Rapala brother also emphasize that the line is attached directly to the eye of the lure without the use of a snap or swivel. Again this is to insure a natural movement. This is a preferred knot among many speckled trout fishermen using mirrolures.
