What kind of wire?
I'll generally use a short,bought pre-tied black wire leader for smallish toothy critters. Swivel on the end...Uni the braid to the swivel.
I keep a couple of rolls of coated wire leader around if I need a longer one...I crimp those. Tie a spider in the braid and then an offshore knot to the leader. To tell you the truth I usually want a swivel in there if I can get one.
Single strand put a haywire and pinch it flat, then the same with a doubled braid line and an offshore knot or an Alberto.
