10 Best Saltwater Fillet Knife 2025 in the United States

The BUBBA Pro Series Lithium-Ion Electric Fillet Knife is designed with serious anglers in mind. Its 8.5-inch handle, made from durable aluminum alloy, ensures a secure grip thanks to the non-slip coating and ergonomic design. Weighing 1.11 pounds, it is lightweight enough for ease of use during extended fishing trips.

One of the standout features is its four Titanium-Nitride coated stainless steel blades, which are not only durable but also non-stick, making the filleting process smoother and more efficient. The blades are also removable, adding convenience when it comes to cleaning and maintenance. The knife's brushless motor provides ample power and torque, ensuring it can handle even the toughest filleting tasks.

The inclusion of a lithium-ion battery and an LED battery life indicator means you won't be caught off guard by a dead battery. However, it's worth noting that the knife is bulky, with package dimensions of 17.5 x 10 x 4.5 inches and a weight of over 3 kilograms, which might make it cumbersome to carry around. Despite this, the heavy-duty build suggests it is a reliable and effective tool for fishing enthusiasts. The product also comes with a charger and a case, making it a complete package for any fishing trip. While the price point might be higher, the durability, power, and convenience may justify the investment for those who frequently fish in saltwater environments.

The Rapala R12 Heavy-Duty Lithium Fillet Knife Combo is designed for serious saltwater fishing enthusiasts. The knife boasts high carbon steel blades with PTFE coating, ensuring durability and ease of use when filleting fish. The combo includes two blades, measuring 6 inches and 7-1/2 inches, providing flexibility for different fish sizes. The blades are serrated, which can be beneficial for tougher cuts but may require more skill for precision filleting compared to non-serrated blades.

The handle is made of rubber, offering a comfortable and slip-resistant grip, which is essential when handling fish in wet conditions. The handle design is ergonomic, reducing hand fatigue during extended use. An added LED light feature allows for filleting in low light conditions, which is a thoughtful addition for early morning or late evening fishing trips. The knife runs on two R12 2 Ah Lithium ION battery packs, providing an impressive 80 minutes of continuous runtime, and it boasts twice the speed and three times the torque of standard fillet knives, making quick work of filleting tasks.

However, the knife's weight of 3.81 pounds may be on the heavier side for some users, potentially causing fatigue. The included sheath ensures safe storage and transportation. The product's 2-year limited warranty offers peace of mind. This knife combo is a solid choice for dedicated saltwater anglers, though its weight and serrated blade may require some getting used to.
