Is exactly what I wanted. A fishing knot for tying a leder. I've never been taught how to do that. I don't like using the steel leders on a swivel. Now I can use this knot to fish without steel leders. Plus other good to know knots. And I can just keep this thing open and sitting out as a 12' ruler. Measuring panfish should be so much easier now when I rent a cheap 14' alumicraft and tool around the lake during this upcoming spring season. I can just keep this on the bench and it is completeley out of the way.
