Rapala RCD Mag Spring Split Ring Pliers 6'/15cm Built with two internally opposing magnets to hold the pliers open, the patented Mag Spring mechanism cannot fail, unlike conventional plier springs. The split ring nose opens rings to size 0 while the built in cutter cuts all lines or tag ends. Features stainless steel jaws and co-moulded grips. For lighter work, get the smaller 4 Inch Pliers.
