Should I Choose a Flexible or Stiff Blade for Filleting, and Why?

When it comes to filleting fish, choosing the right fillet knife can make a significant difference in precision, efficiency, and overall ease of use. One of the biggest decisions anglers and chefs face is whether to use a flexible or stiff blade for filleting. Each type of blade serves a specific purpose, and the best choice depends on the kind of fish you're working with and your preferred cutting technique.

Understanding Flexible vs. Stiff Fillet Knives

Fillet knives are designed to remove bones and skin from fish with precision. The main difference between a flexible blade and a stiff blade is how much the blade bends when pressure is applied.

What Is a Flexible Fillet Knife?

A flexible fillet knife is designed with a thin, pliable blade that bends easily when cutting. This flexibility allows for smooth, close cuts along the bones and skin, making it ideal for delicate fish.

Advantages of a Flexible Blade:

• Perfect for small to medium-sized fish (trout, crappie, perch, etc.)
• Allows for precise and clean cuts around bones
• Reduces waste by maximizing the amount of meat removed
• Offers better control for intricate filleting techniques

When to Use a Flexible Blade:

A flexible blade is best when working with soft, delicate fish where precision is key. If you frequently clean panfish or small saltwater species, a flexible blade will help you remove bones with minimal effort.

What Is a Stiff Fillet Knife?

A stiff fillet knife has a thicker, more rigid blade that doesn’t bend as easily. This design is better suited for cutting through larger or tougher fish where more force is needed.

Advantages of a Stiff Blade:

• Ideal for larger fish (salmon, tuna, redfish, etc.)
• Provides more power for cutting through thick skin and bones
• Works well for filleting and portioning meatier fish
• More durable and long-lasting

When to Use a Stiff Blade:

If you frequently clean large saltwater fish or thick freshwater species, a stiff blade will give you the control and power needed to remove meat efficiently. It’s also useful when processing game fish that require more force.

Which One Should You Choose?

The choice between a flexible or stiff fillet knife ultimately depends on your needs:

For those who fillet a variety of fish sizes, having both a flexible and a stiff fillet knife in your kit is the best solution.
