The Bubba Freshwater E-Glide Replacement Fillet Blade is designed specifically for the freshwater angler who target species such as Walleye, Crappie, Lake Trout and even speckled trout. These blades have been redesigned to have a less aggressive style of blade teeth to deliver optimal cutting action to provide a clean cut of the fillet without ever cutting through skin or back bone of less dense freshwater fish.
