Fishing Knife: How to Choose the Best Model

06 | 05 | 2026

Choosing a fishing knife is about much more than simply selecting a sharp blade. Whether you fish at sea, on a lake or along a river, your knife must meet several essential requirements: resistance to moisture and saltwater, a secure grip, practicality and long-lasting durability.

Whether you are a keen angler, a recreational boater or simply enjoy watersports and outdoor activities, choosing the right fishing knife deserves careful consideration. The right model will serve you for many years, whether for routine onboard tasks or fishing-related activities.

So, how do you choose the best fishing knife? Which features should you prioritise? Should you opt for a plain-edge blade, a folding knife or a multi-purpose model? And what makes Wichard's Aquaterra knives stand out?

Here are the key criteria to help you find the fishing knife best suited to your needs.

Why choose a knife specifically designed for fishing?

Whether you fish offshore, on rivers or on lakes, your equipment should be designed to withstand the environment in which it is used. Moisture, water spray and frequent handling can quickly wear out a knife that has not been designed for these conditions. At sea, saltwater also places particularly high demands on corrosion resistance.

A fishing knife should therefore be designed to assist anglers in a wide variety of situations. It can be used on board a boat, along a riverbank or beside a lake. Easily accessible, it becomes an invaluable everyday tool for many different tasks.

Depending on the situation, a fishing knife can be used to:

  • perform a wide range of cutting tasks;
  • carry out minor jobs during a fishing trip;
  • cut fishing line or other materials;
  • handle ropes and fishing equipment;
  • assist with fish preparation.

Your knife should therefore be as versatile as possible. To learn more, read our article dedicated to the specific features of a marine knife.

Although freshwater environments are generally less demanding than saltwater, regular maintenance remains essential to preserve both performance and service life.

How to choose the best fishing knife

There is no single "best" fishing knife. The best fishing knife is the one that best matches your intended use, your environment and your personal preferences.

Several criteria should guide your decision.

1. Corrosion resistance: essential for saltwater and freshwater fishing

For saltwater fishing, it is advisable to choose a knife specifically designed for marine applications and manufactured from materials capable of withstanding the harsh effects of a saline environment.

Freshwater conditions are generally less aggressive, but the knife is still exposed to moisture. Choosing corrosion-resistant, easy-to-maintain materials remains highly recommended.

Proper maintenance will help preserve your fishing knife's performance and extend its service life, whether you fish in saltwater or freshwater.

2. Blade shape and type

The choice of blade largely depends on how you intend to use your knife.

A plain blade offers excellent versatility and is suitable for many everyday cutting tasks. It is an ideal choice for anyone looking for a simple, practical and easy-to-use fishing knife.

For more specialised applications, other blade profiles may be more appropriate. Whatever your choice, the knife should offer handling and ergonomics suited to your intended use.

The Aquaterra range includes several fishing knife models, including plain-blade versions as well as models incorporating a corkscrew.

3. Handle design and ergonomics

A good fishing knife should feel comfortable and secure in your hand. Handle ergonomics are therefore an important consideration.

On board a sailing boat or powerboat, operating conditions differ significantly from those encountered ashore. Choosing a knife that provides a comfortable, secure grip is therefore essential.

The handle material also contributes to the knife's overall appearance.

Combining style and practicality, the Aquaterra range is available in several colours inspired by the sea and the natural world: Tropical, Atlantic and Anemona. These finishes allow every user to choose a knife that reflects their own style while benefiting from a product designed specifically for fishing enthusiasts.

Aquaterra knives feature an ergonomic Soft Grip handle, resistant to extreme temperatures ranging from -60°C to +100°C. Designed to provide excellent grip, it is manufactured in France and available in several colours.

4. Folding knife or fixed-blade knife?

The choice between a folding knife and a fixed-blade knife largely depends on your habits and intended use.

A folding knife offers the advantage of being compact and easy to carry. Once folded, it takes up very little space and can easily be stored in a bag or pocket. It also offers an important safety benefit: with the blade folded away, there is much less risk of accidental contact with your hand or surrounding equipment.

For everyday use on board, a folding knife is often the most practical option.

A fixed-blade knife, on the other hand, may be preferable for specific applications where immediate blade access is essential. Ultimately, the choice depends on your intended use and personal preferences.

Why choose an Aquaterra knife for fishing and boating?

The Aquaterra range has been developed for anglers, recreational boaters and outdoor enthusiasts alike.

It offers several models to suit a wide variety of needs. Depending on the version selected, you can choose a simple plain blade, a model fitted with a corkscrew, or other practical configurations.

This variety allows you to select a knife based not only on its intended use, but also on your personal preferences.

Choosing an Aquaterra knife offers several advantages:

  • a compact, versatile tool;
  • comfortable, ergonomic handling;
  • a stainless steel blade offering excellent resistance to corrosion, moisture and saltwater while maintaining outstanding cutting performance;
  • a choice of Soft Grip or wooden handle;
  • a lightweight design weighing just 60 g, making it easy to carry;
  • a knife specifically designed for the marine environment.

Ultimately, the best fishing knife is the one that best matches your needs and how frequently you intend to use it.
