Fishing is one of the most popular outdoor recreational activities in the world. Nothing beats an early morning boat ride to the middle of the lake to try your luck with the biggest catch yet. People in the US, in particular, are born fishermen. According to a report by Outdoor Industry, there were over 49 million people in the US who went out fishing in 2020. The report also notes that there were over 880 million fishing expeditions in that year alone. Despite this popularity, fishing can be a pain if you don’t have the right gear, including something as simple as fishing knives. The best fishing knife also means the best fillet knife for anyone who loves fishing trip. In this review, we focus fully on the fishing knife and we will go through our list of the top three knives you can buy.

How to Pick the Best Fishing Knife – Fillet Knife

Well, there are several factors you may want to consider before you buy a fishing knife or fish fillet knife.

As we have noted above, there’s a great variety of knives out there, each with a set of unique features. But it doesn’t mean that these knives will work for everybody. You must always remember that the best fishing blade also is the best fillet knife.

For this reason, it may be a good idea to consider the following simple things before you buy a knife. This will help you land something that works great for your needs so you don’t regret your choice later.

  • Design

The design of the blade can play several roles both in terms of practicality and aesthetics.

For example, extra thin and long blades are very good in streaking large game fish and cutting meat. Thicker blades, on the other hand, are ideal in cutting harder materials such as wood.

However, a good rule would be to pick a versatile design. Blades that feature a serrated end at the top are, in particular, highly recommended.

They are simply so versatile they would cut through anything. It may also be a great idea to pick blades that are easy on the eye as well.

  • Handle

Well, you can’t use a blade without the handle. The great news is that handles are available in very many different designs, styles, and sizes.

But the rule of thumb here is to always pick a handle that feels comfortable on your hands. The last thing you want is for your knife to slide while you’re cutting through something.

This isn’t only annoying but may pose serious safety risks. Additionally, pick a handle that offers excellent grip even in wet conditions. Don’t forget to consider the size as well.

We all know that different people have different sized hands. In that case, pick a knife whose handle fits perfectly into your natural grip. This will make usability quite easier.

  • Tang

The tang plays a huge role in the handling of any knife. It’s basically the rear part of the knife that connects to the handle.

There are two types of tangs. The first one is a partial tang that goes halfway into the handle and the second is a full tang that spreads the entire length of the knife handle.

If you want extra durability and safety using your knife, then pick blades that feature a full tang, well-installed into the grip.

However, it’s still possible to find strong partial tang knives as well. Additionally, pay attention to how the tang is attached to the handle. You want to make sure that both the grip and the blade are strongly connected as one.

  • Quality

Just like the handle, the blade quality also plays a key role in the normal function of any knife. Most blades are constructed from stainless steel and for good reason.

Stainless steel isn’t only highly durable but it’s a rust-resistant material as well that will last for years. In some cases, you may find some knives come with a special coating on the steel designed to prolong their life.

In addition to durability, you may also want to ensure that your blade feels sharp. Some knives, in fact, come with a razor-sharp edge right out of the box. With proper maintenance; they may not need extra sharpening for a long time.

However, the longer you use the blade the blunter it becomes. For this reason, invest in a fishing knife sharpener as well, especially if you see yourself using that blade for a long time during your fishing trips.

  • Size

Finally, it’s also very important to consider the length and thickness of the blade you’re using for the best fillet knife. What size fish fillet knife is best?

As we have noted above, this determines the functionality of the knife massively. Nonetheless, a good portion of fishing knives is often thin and relatively long. The perfect size for a fishing fillet knife is 6 inch and that is ideal for freshwater fillet on trout and panfish. You must try the skinny blade if you do not want to waste any meat and of course, that is good for working around bones.

But the length often comes down to personal preferences. The great news is that many brands will give you the option to pick among a wide variety of blade lengths available.

This will eventually allow you to pick a blade that works just perfectly for you.

What’s the Difference Between Fishing Knife, Hunting, Camping, and Other Knives?

Hunting knives, different models and shapes. 

Now that we went through the list of the best fishing blades you can buy, it’s important to highlight the main difference between fishing, hunting knives, and of course, camping knives. Well for starters, most fishing blades tend to be serrated.

This is done purposely to make it easier for you to cut the rope when you need to. Additionally, you’ll also notice that these knives have a flexible and very thick blade.

The blade can measure between eight to ten inches long. This makes it an efficient tool in cutting out large chunks of fish.

The knives also have stronger handles with excellent grips as well. While the design may differ from one brand to the next, a majority of fishing curved knife brands are smaller and more compact to ensure they can fit into the pocket or in a small bag.
