You can use it for practically everything. Tying on hooks, sinkers, swivels and lure. I use the Uni Knot for tying on Zed spinners and ticers for salmon fishing. It is ideal for joining two ends of fishing lines together, both monofilament and braid. Click on the link to see the full article on the Uni Knot.
