Best Fillet Knife For Tuna Buying Guide

Before choosing the best fillet knife you should consider following options:

1. Blade Shape: The first thing to consider when choosing a fillet knife is the shape of the blade. There are three main types of blades: straight, curved, and half-blades.

Straight blades are the most common and best for most filleting jobs. They have a sharp edge that runs from end to end.

Curved blades are ideal for filleting fish like trout and salmon. With a curved edge, it’s easier to maneuver around the bones, scales, and stomach of the fish.

Half-blades are great for jobs where you need to lever up a steak or fish. They have a straight edge on one side and a curved edge on the other.

2. Blade Length: The blade length is an important factor to consider when buying a fillet knife.

Generally, the longer the blade, the easier the job is. For example, when filleting a large fish, the fish will be supported by the backbone and the knife will most likely be in contact with the cutting board less.

On the other hand, when filleting a small fish, the knife will be in contact with the cutting board more, making it more difficult.

Longer knives also allow you to fillet bigger fish. If you’re new to the job, you may want to consider a longer knife. Otherwise, it’s not crucial to have a long knife.

3. Blade Material: The material the blade is made out of is another important factor to consider when buying a fillet knife.

Generally, there are three types of materials: stainless steel, carbon steel, and high-grade steel.

Stainless steel blades are easy to sharpen and are resistant to corrosion.

Carbon steel blades are inexpensive and sharpen quickly, but they’re prone to corrosion.

High-grade steel blades are expensive, but they sharpen easily, resist corrosion, and last a long time.

4. Handle: The last factor to consider when buying a fillet knife is the handle.

Not only does the handle provide a place to grip the knife, but it also helps to protect your hand from cuts.

For safety reasons, you may want to consider a knife that has a bolster, a piece of metal between the blade and handle, or a finger guard.
