The Blood-Knot Dropper
A dropper line above your fly, lure, or bait is the perfect way to rig split shot. When you snag, the weight will pull free and you'll keep your terminal tackle.
Step 1 Overlap the lines to be joined by 10 inches.
Step 2 Wrap the left-hand tag end five or six times around the standing line, then put the tag end back through the opening held by your fingers.
Step 3 Switch hands so your left thumb and index finger hold the opening. Use your right hand to make five or six wraps around the standing line with the other tag end. Put it back through the same opening but in the opposite direction.
Step 4 Lubricate the knot with saliva and pull gently on the standing line portions. At least one of the tag ends must stick about 5 inches out of the knot for use as a dropper.
