I thought crimps were for wire trace but someone else on here will know more. I make a small loop for accommodating a hook or a swivel – pass the wire though the crimp, add the hook or other tackle item, then double it back and use pliers to squash the crimp onto the line, I use a knot as well for extra confidence that the thing will hold together. Wire is quite hard to knot well, especially the thicker stuff, so a crimp helps.
