It is important to choose the right fillet knife for your needs, as the wrong knife can easily cause you to waste precious meat, slow down cleaning and preparation tasks, and even increase your risk of injury while filleting your catch.

Also, be sure to look for a fillet knife that has an ergonomic handle that will be comfortable in your hand while giving you the necessary power to control the blade and keep a firm grip, which can be difficult with some knives when your hands become wet.

Not only does a firm, comfortable grip offer safety for the user, but also reduces unnecessary strain while cleaning and filleting meat.

An included sheath for protection of the blade and the carrier is always a plus when choosing a fillet knife. Those with a built-in sharpener are especially helpful as well, because it lets you perform a quick blade sharpening while you are preparing the catch, with no need to stopand search for a sharpener to get the job done.

Also, notable is the mounting options for the fillet knife sheath, which can vary by product and manufacturer.
Look for those with a standard belt loop, as well as handy clips and loop attachments for backpacks, and even pockets for storage, as those features can come in handy for a variety of users, especially when out in the field.

With the wide selection of unique types of fillet knives available today, it is easy to find one that works well for your task, has the features needed to do a good job, and is well within your budget. Here are some tips to help you select the perfect fillet knife.


Tips for Choosing a Fillet Knife

• Blade – One of the most important choices when selecting a fillet knife is obviously the blade. Choose a thin and durable blade with some flexibility for ease of use. It should hold a sharp edge and be the right length for the meat or fish you plan to clean.
• Handle – Do not underestimate the importance of the handle of your fillet knife when making your selection. Choose an ergonomic handle with a comfortable fit that allows you to have control over the blade. Safety and comfort are key features to seek in a good fillet knife.
• Sheath – While not an actual part of the fillet knife, the sheath is an extremely important accessory, as it protects the blade and keeps you and others safe during transport. Sheaths come in a variety of materials like leather, nylon, and plastic.
Either type is fine, but those with a built-in sharpener get extra points. In addition, be sure to pay attention to the mounting options of the fillet knife sheath to ensure it has the features you prefer, such as belt loop mounting or additional hooks for attaching to tackle boxes, etc.


Fillet Knife FAQs

What is a Fillet Knife Used For?

A fillet knife features a thin, flexible, and typically short blade that offers the perfect precision, control, and maneuverability for cleaning fish and other meats for cooking. Fillet knives are made specially for removing bones, skin, and entrails from a fish to form fillets.

While cleaning and preparing fish for cooking is the main use of a fillet knife, it is also excellent for use on other types of meat such as poultry and beef.

Hunters and fishers are also big fans of fillet knives for use when cleaning big game and fish in the field. In fact, just about anyone who cooks – from professional chefs to the ordinary home cook, can benefit from having a favorite fillet knife to handle all of the precision filleting, cutting, dicing, and slicing these popular knives can do.


Is a Boning Knife the Same as a Fillet Knife?

While the fillet knife is technically a part of the boning knife family, the popular knife is actually quite different in its features and functions.

A fillet knife has a thinner and more flexible blade than boning knives, offering the user the chance for more precise cuts with less wasted meat. In addition, fillet knives are super flexible, making for better maneuverability when removing skin.

A major difference between the boning knife and the fillet knife is that the fillet knife is curved, were the boning knife has a completely straight blade. The curving of the fillet blade gives added flexibility when cleaning fish and meat and allows easier cuts to help make the job so much quicker to complete.


How Sharp is a Fillet Knife?

Razor sharp! And just how sharp is that, you ask? Typical kitchen knives have a 20-degree edge bevel, and the preferred edge bevel is 12 to 15 degrees per side for filleting. This extreme bevel provides precise, easy cuts, with a decent resistance to dulling.

If you are doing a light fillet job or a task that does not cut into bones or monofilament and fibers with your fillet knife, a 15-degree bevel should do the job just fine. Having a sharp fillet knife at all times is crucial for success when filleting fish and other meats.

The sharper the fillet knife, the more precise and attractive the fillet will be.



No matter what type of meat you want to fillet, there is a perfect knife for the job. In fact, it is actually a good idea to have two or three fillet knives with different blade lengths and features, so you are prepared for any occasion.

Once you find the perfect fillet knife for you, it will be almost impossible to work in the kitchen without it!

If you don’t have the luxury of getting several of these amazing fillet knives and you have to choose just one fillet knife for your tasks, the KastKing Fillet Knife is professional yet rugged and comes in a variety of sizes, and offers durability and precision needed for perfect fillet work every time!
