The Eugene Bend knot is one of the strongest hitch knots used for attaching terminal tackle. Rather than using a single line for wrapping around the standing line, it employs a double line as a loop is first formed before wraps are made. One distinctive feature of the knot is that it will often “pop”, either by feel or as an actual audible popping sound, when the knot is tied correctly and cinched down tight.
Here are the knot strength efficiency numbers for the Eugene Bend Knot as tested across the three major line types.
See the Fishing Knot Strength Chart for more data and details on the testing methodology.
