There are a million other uses for fishing knives that might not even occur to you until you’re in the moment, at which point you’ll just be grateful that you came prepared. I have laid out guidelines on things to consider when purchasing a fishing knife, the types of knives, the best of the best, how to sharpen and maintain your fishing knife, and answer frequently asked questions about fishing knives. Let’s kick this off!

Things to Consider When Picking Fishing Knives
1. Blade

The blade in your saltwater fishing knife needs to be resistant to water and rust, or it won’t last long. Most anglers feel that the best fishing knives have quality stainless-steel blades.

Ideally, any fishing knife you use should have a razor-sharp blade that can maintain its edge for a while and not immediately rust from either salt water or fish guts and fluids. Many knives have corrosion-resistant blades but how well you maintain the knife is also a factor.

Blade length is also an important factor when considering which fishing knives to purchase or use in a certain situation. A fillet knife typically has a longer blade, typically 7 inches – 9 inches in length, while other, more versatile knives have much shorter and sturdier blades.

2. Handle

Aside from the blade of the knife, the handles are the next important factor to consider. The ideal handle for a fishing knife will be sturdy with a non-slip grip to avoid dangerous accidents.

The handle should also be durable and resistant to deterioration from constant exposure to water. It must also be hefty enough to be used to club a fish if necessary. Some good materials to consider when looking at knife handles are; rubber, hard plastic, cork, and treated wood.

3. Uses

The kind of knife that you need is also dependent on what you want to use the knife for. While virtually any knife can be used for anything in a pinch, some knives are just better suited to filleting fish or gutting fish.

Types of Fishing Knives

As I said, different fishing knives have different uses. While you can use some knives in a variety of ways, it’s best practice to just buy the appropriate knife for whatever activity you’re doing. You can ruin a fillet knife if you use it to cut rope, for example, so it’s best to avoid that and just be prepared.

If you don’t want to buy several knives, or if you can’t afford to, that’s also okay. There are affordable fishing knives that can serve several functions without breaking the bank.

1. Fillet Knives

A fillet knife is best used for what it sounds like; filleting fish! Unlike the other types of knives, this one is pretty specialized and not for versatile use. A fillet knife has a long, thin, curved, razor-sharp blade to make cleaner and more precise cuts when separating the fillets from the spine and ribs of the fish.

This fillet knife comes with a sheath and features a 7 inch blade length on a stainless steel blade and a tapered non-slip grip as well as safety guards to prevent injuries from the blade and fish. It’s very lightweight at only 0.7lbs. The blade is Tri-Nitride coated, which makes it rust resistant, so this fillet knife will have a long life.

2. Fixed Blade Knives

Fixed blades are more durable than folding knives because the blade extends all the way into the handle. This makes them the perfect choice for dealing with larger fish as well as anything else that might need to be cut with minimal effort, like a rope. They can also be used for heavy-duty tasks around a campsite or boat.

However, these knives can be a little big and unwieldy. Most fixed blade knives will come with a sheath so that they can be stored and transported safely.

3. Manual Fold Pocket Knives

Fishing pocket knives are a very nifty thing to have on hand in a number of everyday scenarios, and that’s no different in a fishing situation. These knives are great in a variety of fishing and camping situations, and if you pick a good one, you’ll have a very useful, sharp, and versatile knife. These knives can be safely kept in a pocket because the blade folds into the handle.

Their small size means that they’re fairly easy to handle and can be used with one hand without fear of injury. You can use it as a bait knife or to cut your line, and it’s most ideal for dealing with smaller fish and smaller bodies of water.

7. Multi-functional Knife

This may be the best kind of knife to buy if you’re working under budget constraints, as it can do most of the things that you need. A multi-functional knife is kind of like a fishing pocket knife but for fishing. You can use this knife to do several things, and it’s very portable and safe to use.

FAQs
– How do I sharpen a fishing knife?

You can easily ruin your best fishing knife or fillet knife by sharpening it the wrong way. Ideally, your blade will hold its edge so well that you won’t have to do this, but there are several methods you can use; using a whetstone, using an oil stone, or honing your knife regularly.

There are lots of helpful videos online that you can watch to make sure you’re using the right technique and not actually making it worse.

– How do I maintain my fishing knives?

It’s important to clean your fishing knives regularly to avoid deterioration. It’s advised that you wash your knives after every fishing excursion in warm, soapy water and then thoroughly dry them afterward so that they’re not exposed to water for unnecessary amounts of time.

This varies from state to state, so it’s best to familiarize yourself with your local laws and your state laws. There might also be laws on how to carry your knives openly.
