Saltwater and trophy freshwater fishermen have a fillet knife that can handle any big fish in the Piranha from Mister Twister, the pioneer in electric fish cleaning technology. Every bit as rugged as the classic Mister Twister Electric Fisherman, the Piranha, features 25% more torque and 15% more speed than most other electric knives, so it will handle the tough scales and skin of any trophy fish. The real key to its cutting power is in its 9" heavy duty stainless steel blade. More power, more torque, and more speed make the Piranha, "Bad to the Bone!" 9" blade length means less time cleaning fish and more time on the water.
