The Big Eye Swivel Leads feature a swivel with a large eye. This easily attaches the lead to lead clip or connector. In addition, this lead has a vertical eye. Do you want a very direct hookup, cut the swivel off the lead and attach the lead clip directly to the vertical eye of the lead. The clip always lies flat or the bottom due to the position of this eye and will scare suspicious carp less and hook more directly. On frequently fished waters this can make all the difference!
