Fishing Knots
Uni Knot
Duncan loop, grinner
DIFFICULTY ●●○○○
A sliding barrel of wraps tied through a loop of the line itself. Snug it to the eye for a tight connection, or leave it loose for a free-swinging loop that improves lure action.

The Swiss Army knot of fishing: one motion ties hooks, joins lines (two unis back to back), and snells. Learn this single knot and you can rig almost anything.
Where it fails
Six wraps for mono, a couple more for braid. Like every fishing knot, cinch it wet and slowly — dry friction burns line and costs you strength invisibly.
