The Bubba E-Glide EFK Blades are designed with the freshwater angler in mind who targets more delicate species such as Panfish/Crappie, Walleye, Lake Trout, and even Speckled Trout. These blades have been engineered to have less aggressive blade teeth to deliver optimal cutting action and provide a clean cut of the fillet without going through the skin or backbone of less dense fish. Available in both 7 and 8 options.
