10 Best Fishing Knives 2025 in the United States

The KastKing Bait Knife and Fillet Knife with a 9-inch blade is a versatile tool designed for various fishing and food prep tasks. The blade is made from G4116 German stainless steel, known for its sharpness and durability, making it effective for both fresh and saltwater applications. The non-slip super polymer grip ensures safety and comfort during use, which is essential for handling slippery fish.

It comes with a protective sheath that securely locks the knife, with drainage slots to keep the blade dry and sharp. This thoughtful design enhances both safety and maintenance. Users have praised its sharp edge and flexibility, making it suitable for filleting fish of different sizes and for steaking large game fish like salmon and tuna.

While the stainless steel handle is durable and easy to clean, it may not be as comfortable for prolonged use compared to softer materials. The knife is also lightweight, which can be both a benefit and a drawback depending on personal preference. Another consideration is that the knife is hand wash only, requiring extra care to maintain its condition. If you need a reliable and sharp fillet knife for fishing and food preparation, the KastKing Bait Knife and Fillet Knife is a solid choice, although you may want to consider how the handle material aligns with your comfort needs.

The KastKing Speed Demon Pro Lithium-ion Electric Fillet Knife is a high-quality fishing knife designed for efficiency and ease of use. It features a powerful high-torque motor that makes filleting quick and smooth, regardless of the fish size or species. The knife includes 420 stainless steel blades with a titanium Vapor Deposition coating for durability and corrosion resistance. The pack comes with four different blades (7" and 9" Finesse blades, 9" Talon blade, and 12" Talon blade), providing versatility for different filleting needs.

The ergonomic Thermoplastic Elastomer (TPR) handle ensures a firm, non-slip grip, reducing hand fatigue during extended use. One of the standout features is its extended battery life; the 12.6v lithium-ion battery provides up to 1 hour and 40 minutes of continuous runtime, and the pack includes two batteries for uninterrupted use. The custom-molded EVA carry case is a convenient addition, making it easy to store and transport the knife and its accessories.

Users will appreciate the power level display and overcharge protection features that ensure battery safety and longevity. However, the knife's weight (4.07 pounds) might be a bit heavy for some users, and its larger size (16.5 inches in length) may not be ideal for those looking for a more compact option. This knife is best suited for avid anglers who require a reliable, high-performance fillet knife with the convenience of cordless operation.

The KastKing Intimidator Bait Knife and Filet Knives set is a solid choice for fishing enthusiasts. It features ultra-sharp G4116 German Stainless-Steel blades that maintain precision cutting edges for longer periods, suitable for both freshwater and saltwater environments. The set includes various blade lengths: a 5” stiff blade bait knife with a serrated edge, and 7”, 9” fillet knives alongside a 9” steaking knife, which are thinner and more flexible for precise filleting tasks. These variations offer versatility for different cutting needs when fishing.

The ergonomic, slip-resistant handles ensure comfort and control, reducing the risk of slipping while working with the knives. Additionally, the set comes with a durable storage bag for convenient carrying and protection of the knives, which is particularly handy for travel and outdoor use. The included professional honing rod makes it easy to maintain a razor-sharp edge, enhancing the longevity and effectiveness of the knives.

However, it should be noted that the knives are hand wash only, which might be less convenient for some users. Furthermore, while the non-slip handles are beneficial for safety, they may not be as comfortable for extended use. This set is a practical choice for those needing a reliable and comprehensive fishing knife set.
