Competition fly-fishers introduced the world to Czech nymphs. These simple scuds and grubs dressed in a shiny, translucent shell are elegant and effective fish-catchers. The Czech Nymph / Scud Cutters stamp out shell-back material in just the right shape to wrap over your dubbed fly body. Add a wire or mono rib for durability, and you've got the kind of pattern that wins championships. Available in each size or as a complete set that includes all sizes.
