The present invention 10 is an improved electric knife with several enhancements which make it uniquely suited for use in its intended watery environment. In case it is accidentally dropped in the water, it has several floatation chambers 54 in the handle 24 and the end cap 52 that will keep it afloat and nearly water and damage free for a reasonably long period, certainly time enough for any reasonably serious effort at retrieval to be effective. The end cap 52 is highly buoyant, having a sealed partial vacuum chamber 54. The housing has several sealed buoyant air chambers 54 in the. rearmost area to directly offset the weight of the battery pack 36. The motor housing unit also provides buoyancy and floatation by the presence of the water-resistant seal 63 at the juncture of the knife blades 42 and the handle housing 24. The critical areas around switches 44, 50 and access openings are also watertight for operating in wet or rainy conditions. Additionally, there is a light 48 in the top front area of the handle with its nearby water-sealed 56 switch 50 for illuminating the work area when operating under night or low light conditions. The present invention comes with a carrying case 18 and many additional components: a recharging unit 34 for recharging the power pac 36, a reenergizer 38 for charging the power pac 36 and operating under AC simultaneously, a spare power pac 36, 2 different sized interchangeable blade sets 26, a blade cover 28, DC 12 volt power cord 30, AC power cord 32 and the fillet knife housing unit.
