【Say goodbye to power anxiety】 Our electric fillet knife comes with an efficient 12V fast charger and two 1500mAh replacement batteries. A single battery provides up to 4 hours of continuous runtime and recharges fully in just 1 hour. When one battery drains, simply swap in the fully-charged spare to get back to work instantly. Perfect for all-day fishing trips or multi-day excursions, ensuring you're never left powerless. 【Professional 2 Blade Set】Fillet knife set includes an 8-inch and a 10-inch detachable stainless steel blade. Each blade undergoes passivation and mirror-polishing process, creating a dense protective oxide layer. This makes them highly corrosion-resistant and rust-proof while significantly reducing meat sticking for incredibly smooth, clean cuts. Effortlessly handle everything from delicate flounder and cod to large, tough-skinned tuna, swordfish, and halibut for perfect fillets every time. 【Secure & Comfortable, Non-Slip Grip】The handle is wrapped in a soft, tactile TPE material and features a perfectly balanced ergonomic design. It provides a superior, non-slip, and secure grip even when wet or covered in fish slime. This comfort-focused design minimizes hand fatigue during long sessions, allowing you to focus all your attention on the blade and achieve millimeter-level precise cutting. 【Safety Lock, Prevents Accidental Activation】Your safety is our priority. We've integrated a unique safety lock button on the trigger guard. When the tool is not in use, simply press the lock button gently and the trigger will be completely locked and cannot be pressed. This crucial feature effectively prevents accidental start-ups during storage, transport, or handling, greatly enhancing safety for you and your family—especially important on a moving boat. 【Full set Portable】The product is equipped with an ultra-thin and lightweight portable case, which can neatly store the main unit, two batteries, a charger and two professional blades. The box is wear-resistant. Its ultra-thin design enables it to be easily placed in a cabin storage cabinet, car trunk, luggage bag or backpack, making it an ideal companion for your travels and outdoor fishing. Wherever you go, you can always carry a complete set of professional fish-slicing tools with you.
