To prepare a batch of weighted hooks you need: Medium or heavyweight grub/shrimp hooks, size 4 to 16. Square or rounded lead wire - fine, medium and heavy. Superglue With a hook in the vice - run a bead of super glue from just around the bend to just behind the eye. Wind a length of lead wire on to the hook (the bigger the hook the thicker and heavier the wire.) Remember to leave a gap at the bend end and eye end of the hook, this gives room to tie in and tie off without creating bulk. Nip off the waste ends of the wire with your finger and thumb. Remove the weighted hook from vice and leave to dry.
