Sharpening a fillet knife can be frustrating but it’s not your fault.
Fillet knives are thin and flexible by design, which makes it difficult to hold a consistent angle on traditional sharpening stones. In this video, we break down why fillet knives are so hard to sharpen and show a simple, repeatable system to get a sharp edge at home and keep it sharp in the field.
At home, we use the Work Sharp Knife & Tool Sharpener (KTS) to support the blade and eliminate flex—making it easy to hit a consistent angle and raise a burr quickly.
In the field or on the boat, we use a kitchen pull-through sharpener for fast touch-ups. It’s simple, easy to use with wet or gloved hands, and keeps your knife working until you can get back to a full sharpening setup.
In this video:
Why fillet knives are difficult to sharpen
How to sharpen a fillet knife at home (KTS method)
How to keep your knife sharp in the field
When to use ceramic vs diamond touch-ups
Tips for maintaining a consistent edge
If you’re tired of fighting the flex, this method will make sharpening fillet knives simple and repeatable.
Let us know in the comments if you think we got it right—or if you want to see us sharpen one on a stone (we’d really rather not).
