This Lithium Ion Cordless Electric Fillet Knife is ergonomically designed to fit perfectly in your hand. Saying true to their roots by incorporating the iconic non-slip grip handle which allows you to cut through fish like butter. The lithium ion battery has the longest run time of any electric fillet knife on the market so you can stack fillets until you’re out of fish. The engineered ventilation has been designed to maximize motor transmission output giving you an incredible amount of torque. Included are four different blade styles — 7” E-FLEX, 9” E-FLEX, 9” E-STIFF and 12” E-STIFF — that reflect their legendary tapered flex and stiff fillet knives. These blades are constructed out of high carbon stainless-steel and coated with titanium nitride making them extremely corrosion resistant. The electric fillet knife comes in a premium EVA molded carrying case which allows you to break apart the storage units for easy cleaning. This knife contains a secondary replacement battery, charging cord, and all batteries contain a battery life indicator so you can rest assured that you'll never run out of juice.
