Start With a Clean Knife

Saltwater and fish residue can quickly damage your knife’s steel. Before sharpening, always rinse your knife thoroughly with fresh water, dry it completely, and wipe off any remaining salt or debris. This step prevents corrosion and protects the blade’s edge.

If you use a Victorinox Filleting Knife, keeping it clean is especially important. Their steel is designed for long-lasting sharpness, but salt and grime can shorten its lifespan. Regular cleaning is the first step in fishing knife care that preserves your investment.

Use a Sharpening Steel Correctly

Sharpening steels realign the blade’s edge, keeping it sharp between full sharpenings. Here’s how to use one like a pro:

• Hold the sharpening steel vertically with the tip resting on a stable surface.

• Position your filleting knife at a 15° angle against the steel.

• Swipe the blade from heel to tip in one smooth motion.

• Alternate sides with each swipe.

• Repeat this process 6 to 10 times per side.

  
  

For best results, use a Victorinox Round Sharpening Steel. It’s designed to maintain the precise angle needed for filleting knives.

Pro tip: If your knife is very dull, start with a whetstone before using the sharpening steel. This removes more metal and reshapes the edge.

Test the Edge

After sharpening, test your knife’s sharpness by slicing through a sheet of paper. A sharp blade will cut cleanly without snagging. If the blade catches or tears the paper, sharpen again using the steel or whetstone.

This simple test helps you avoid dull blades that can slip and cause accidents.

Maintain Sharpness Weekly

Sharpening your filleting knife regularly keeps it in top condition. It’s better to sharpen a little and often than to wait until the blade is blunt. Weekly maintenance saves time and effort in the long run.

Storage Matters

How you store your filleting knife affects its sharpness and safety. Never toss knives loose in a drawer where edges can dull or cause injury. Instead, use one of these options:

• A Knife Wrap with multiple pockets protects each blade individually.

• Blade Guards slip over the edge for safe storage.

• A Magnetic Knife Rack keeps knives accessible and secure.

  
  

Proper storage protects your knife’s edge, your gear, and your hands.
