In My Opinion, The Best Fillet Knife Is Made From The Highest Quality Metal And Should Simply Slice Through The Skin. This Is My Top Ten Sharpest Fillet Knives

A fillet knife is just as essential as baits and reels for every fisherman. It is an important  piece of kit that any fisherman who needs to cut their bait in the right size fillets a simple task. However, despite the fact that the initial concept was passed down generations, some things changed over the years and fillets knives are not built the same anymore.

Some knives corrode when exposed to saltwater, others break when under pressure while others are built with less-than-average quality. This makes choosing a fillet knife that can sustain your needs, not an easy task. With that in mind, we have put together a list of the 10 best fillet knives that offer durability, reliability, and flexibility.

Criteria for Choosing Fillet Knives

Material

The first consideration you should make when shopping for a fillet knife is the material used in making a particular model. Make sure that the blade is made from a strong material, preferably stainless steel with an anti-corrosion coating. A blade made from a low-quality material will get damaged easily, get corroded or bent when trying to cut something. The type of steel used varies from one manufacturer to another, and an anti-corrosion coating is often applied. Some brands also include a non-stick coating to minimize sliding resistance.

There are different material options when it comes to the handle. Common ones include plastic, wood, and rubber. Wood is slippery when it gets wet and doesn’t provide a very good grip. It also has a tendency to absorb water, which could result in unpleasant smells. Rubber and plastic are good choices as they offer firm grip without adding too much weight.

Blade size

This is pivotal to your decision as it defines the task. Go for a small blade if you intend to use the knife for limited domestic applications and small cutting needs. Larger blade size is more suitable for dealing with large fishes at the lake or in restaurants and fish shops.

Blade flexibility

A flexible blade is incredibly important, especially if you are filleting small fish. If going for a larger knife, ensure that the blade doesn’t offer too much flexibility because it will only make cutting through fillet more difficult. The flexibility of a blade usually depends on its thickness, with long and thinner blades being more flexible than thicker ones.

Safety features

Many people tend to overlook safety and end up with knives that don’t offer much protection from the blade or fish spines. Most fillet knives incorporate a finger guard while others have a dimpled handle. There are those that are provided with a free cover for the blade, allowing for transportation without risk of injuries.

Making the best decision when it comes to fillet knives shouldn’t be hard work. as long you keep an eye out for things like blade length, handle material and safety, you will get something worth every penny you spend. The models reviewed in this post are some of the best money can buy. And while we strongly recommend all of them, your decision ultimately depends on the features you want most and what you’re willing to spend.
