Choosing the Best Fish Fillet Knife for You
If you are buying a fish fillet knife for the first time, it’s a good idea to examine all the features in detail so as to figure out what’s best for your needs.
When it comes to blade material, there are various schools of thought that support the use of different materials. Sure, ceramic seems like the best option ever because of the simple fact that it can easily be sharpened and holds its sharpness a little longer than other materials, but they break quite easily too. And top-quality ceramic blades do not come cheap. However, there are plenty of other viable options including stainless steel, forged blades, carbon steel, and high-carbon stainless steel.
This is the most common metal you’ll find around the kitchen place. It is durable, easy to sharpen, and inexpensive too.
Slightly more expensive than stainless steel, carbon steel is an easy-to-sharpen premium metal that holds a sharp edge for a long time.
High-Carbon Stainless Steel
As the name suggests, the high carbon stainless steel has a little more carbon in the steel mixture, giving it superior strength. You’ll have to pay top dollar for this but its quality and craftsmanship make it a worthwhile investment.
Today, fillet knives come in a hue of colors, so you can pick a hue that matches your décor. Some people like subtle colors, while others prefer darker hues, which are more forgiving in case of dirt. Some even like to match their cutlery sets with the rest of the kitchen decor. This is completely up to you—have fun choosing!
You can find a fillet knife that fits just about any kind of budget. You’ll find knives for only around $20 and knives prices at several hundreds of dollars. It all depends on the quality of the knife, brand name, durability, and finish.
Additionally, if you want to get an electric fish fillet knife, expect to spend more. You’ll want to invest in quality and durability, so it’s best to not cut too many corners when it comes to these electric knives.
You should get a knife with a high-quality handle that feels right in your hand. It should both ergonomically design for maximum comfort, boast a good grip, and be well-balanced to avoid overexertion.
The more comfortable it is, the easier it will be for you to prepare many pounds of fish. If you get a low-quality knife that is too heavy, you won’t want to use it every again—and there goes your investment.
There are typically three types of material in fish fillet knife handles:
Wood is a classic material that feels great in your hands. However, it tends to hold onto bacteria quite a bit and as far as durability goes, it pales in comparison to other materials used to make handles.
Laminate is pretty much a mix of plastic and wood. You might confuse it for wood because of its resemblance but, unlike wood, laminate is far easier to care for. Plus, it’s also more durable.
Plastic is very user-friendly, to say the least. It’s easy to maintain and incredibly light, too, which makes it a go-to handle material for easy-to-carry knives. However, since it is somewhat fragile, it may crack a little too easily with wear, especially when it’s exposed to high temperatures.
Because of the nature of filleting, you’re going to need a flexible fillet knife that won’t break. And I don’t mean that you should go for a flimsy knife; certainly not! A filleting knife should be flexible in the sense that you can easily maneuver around the meat with little or no difficulties at all. Preferably, something short that fits in your hand just fine.
While blade length is a matter of personal preference, there are some specific things that you have put into consideration. Blades come in various lengths and each length is suited for a particular type and size of fish. And so, it all depends on the type and size of fish that you’re more likely to go for. But to put things into perspective, there are generally three kinds of blades. Short blades, medium-sized blades, and long blades.
Short blades are fairly easy to take with you and offer better control and maneuverability when you’re dealing with smaller fish species such as crappies, yellow perch, and sunfish.
These fish fillet knives, on the other hand, are better suited for larger fish. They range in size between 7 and 7.5 inches long. They’re the perfect pick for preparing trout, bass, and walleyes.
Lastly, there are the larger sized blades. They give you greater control and let you prepare bigger fish, such as large salmon and broad-shouldered pike. However, keep in mind that the larger the blade, the more awkward it is to carry it with you.
Ease of Use
Think of all the cutting and skinning involved when filleting fish. It takes a lot of hours, right? That’s why you want to opt for a simple tool that’s easy to maneuver.
While most knives are pretty easy to use, some are a little more complex than others. For the inexperienced chef, having a fillet knife that takes the guesswork out of meal prep is refreshing. A no-frills approach is our favorite approach.
