Having a good fillet knife is as important as a good rod when it comes to fishing. But getting the right one to serve your needs can be a daunting task since there are many of these fillet knives on the market. 

Well, not to worry, because after reading this buying guide you’ll certainly find it easier to choose a suitable one that will suit your specific needs. Here are some very important things to consider when shopping for one.  

The Blade

The blade is one of the most important parts of a quality fillet knife, as it determines how smooth the cut will be right through the fish. It’s very important you keep in mind the following points in blade selection so that you get the right knife for your specific needs.

  • The blade material: A blade made of corrosion resistant alloy will definitely last longer even when used in a salty environment or salt water. And a perfect material of this blade is one made with corrosion –free stainless steel or titanium.
  • Blade size: This comes in various sizes between 4 to 9 inches.  The size of blade you need depends on the type and size of the fish you usually work with. For larger fish, it is required you use larger sized blades as this will help to get the job done easily. Shorter blades will work great when used for smaller fish like crappie. 
  • Thinness and sharpness: This is one characteristic to look out for as this can play an essential role in determining how smooth and clean your cut will be right through the fish without leaving any rough edges behind. As you should know, the thinness of a blade matters a lot since thicker ones require a lot of effort to cut through the fish and bone.

Blade Strength

As well as the size and thinness of the blade, you will also want to consider the strength. A Flexible blade will make a lot of difference when used for removing bones. But they are not suitable for slicing larger fish due to its flexibility and less strength. Instead, a thicker one is preferable. 

Handle

Fillet knives come in different variety of handles, and having one that offers a comfortable grip will make the slicing a lot easier and quicker even when used with your wet hands. Like other types of knives, the popular options are the ones made of traditional wood, rubber or plastic. But whichever one you plan to buy always make sure that it fits your hand and it is comfortable to hold while filleting and boning. 

Electric Powered

An electric knife is a suitable choice if you’re finding a quicker way to fillet a lot of fish after a great catch. The electric types are either corded or cordless. The corded types require you to connect it to a power source when using it while cordless types come with a rechargeable battery. Most electric types offer an opportunity to change the blades for different cutting purposes; this means you don’t need to worry about getting several knives for different types of fish and sizes. 

Cost Factor​

In most cases, your budget will determine whether to get one that is expensive or cheap. But from experience, the expensive ones are usually made with high-quality material which makes it durable and long-lasting.  However, by reading the product reviews carefully you should be able to get one with sound quality that will also suit your budget.  

Warranty

For a satisfactory benefit, this is one of the essential things you have to check when shopping for your knife. This warranty in most cases ranges from a minimum of 1 year to a lifetime.  

There are many in the market which come with a limited warranty but it is best you get one that offers a lifetime warranty against defect.
