Best Fillet Knife Sharpeners: Complete Buying Guide 2025
Why You Need a Good Fillet Knife Sharpener
As a chef who has spent years in both home and professional kitchens, I know this truth: a sharp knife is your best friend. A dull blade is not just a pain to use – it’s risky. When you try to cut with a dull knife, you push harder. This means less control and more chance of the knife slipping.
I’ve seen many good fillet knives go to waste because people didn’t keep them sharp. That’s why I’m sharing my hands-on tests of the best fillet knife sharpeners on the market today.

2. Horl 2 Oak Rolling Knife Sharpener

The wooden base isn’t just pretty – it stays put on the counter when I’m sharpening. After using it, my knives slice through fish so cleanly that I can make perfect sashimi cuts.
Who Should Buy This: This is perfect for knife enthusiasts who want precision control over their sharpening angles. If you have both Western and Japanese knives, you’ll love the flexibility this offers.
3. Brod & Taylor VG2 Classic Knife Sharpener

- Ergonomic rubber grip handle and base
- Compact design fits in kitchen drawers
What I Like: The four stages let me choose how much work my knife needs. For my fillet knives that just need a touch-up, I can skip right to the fine ceramic rods.

After using this, my knives glide through fish flesh without any tearing.

How to Choose the Right Fillet Knife Sharpener
After testing dozens of sharpeners over the years, here’s what I look for:
1. Type of Sharpener
Electric Sharpeners like the Chef’s Choice and Presto are fast and consistent. They’re great if you:
- Sharpen knives often
- Want quick results
- Don’t want to learn manual sharpening techniques
Manual Sharpeners like the Horl 2 and Brod & Taylor give you more control. Choose these if you:
- Want to develop your sharpening skills
- Have expensive knives that need careful treatment
- Prefer not to rely on electricity
Portable Sharpeners like the Smith’s and AccuSharp are perfect if you:
- Need to sharpen on the go
- Have limited storage space
- Want something simple for occasional use
2. Sharpening Stages
I’ve found that multi-stage sharpeners give the best results:
- Coarse stages reshape the blade and fix damage
- Medium stages refine the edge
- Fine stages polish for smoothness
3. Angle Control
This is crucial for getting the right edge on your fillet knife:
- Western knives typically need 20° angles
- Japanese knives work best at 15° angles
- Fillet knives often benefit from sharper angles (around 12-15°)
4. Ease of Use
Look for:
- Clear instructions
- Comfortable grip
- Stable base that won’t slip
- Safety features like finger guards
5. Versatility
Consider what other knives you might want to sharpen:
- Can it handle serrated blades?
- Does it work for different knife thicknesses?
- Will it sharpen other tools like scissors?
How to Keep Your Fillet Knife Sharp Longer
Here are my top tips from years of fish prep:
- Use a cutting board – Never cut on glass, stone, or metal surfaces
- Hone regularly – Use a honing rod before each use
- Clean and dry immediately – Don’t leave knives wet or dirty
- Store properly – Use knife blocks, magnetic strips, or blade guards
- Sharpen before knives get dull – Regular light sharpening is better than occasional aggressive sharpening
My Sharpening Routine
I’ve developed this routine over years of daily knife use:
- Daily: Quick hone with a rod before using my fillet knives
- Weekly: Touch-up with fine ceramic stones or the fine stage of my sharpener
- Monthly: Full sharpening session through all stages
- Seasonally: Inspect for damage and repair as needed
Frequently Asked Questions
How often should I sharpen my fillet knife?
If you use your fillet knife regularly, aim for a light sharpening every 1-2 weeks. Daily use on fish may require more frequent sharpening. I can tell it’s time when the knife starts to tear rather than slice cleanly through fish skin.
Can I sharpen serrated fillet knives?
Yes, but you need the right tool. The Chef’s Choice, Brod & Taylor, and AccuSharp models I reviewed all work well on serrated edges. Focus on sharpening the flat side of the blade and be gentle with the serrated edge.
What angle should I sharpen my fillet knife at?
Most fillet knives work best at angles between 12-20 degrees. Thinner angles (12-15°) give a sharper edge that’s ideal for delicate work but may dull faster. For general use, I recommend 15-17 degrees as a good compromise between sharpness and durability.
Electric or manual sharpener – which is better?
It depends on your skill level and needs. Electric sharpeners are faster and more consistent, especially for beginners. Manual sharpeners give you more control and are often gentler on expensive knives. I use both – electric for quick touch-ups and manual for fine-tuning.
How do I know if my knife is truly sharp?
A truly sharp knife will:
- Slice through paper without tearing
- Cut a tomato without squashing it
- Slice through fish without catching on the skin
- Feel smooth when cutting, with no pulling or tearing
Can I ruin my knife by sharpening it wrong?
Yes, improper sharpening can damage knives. Using too coarse an abrasive, applying too much pressure, or sharpening at inconsistent angles can all harm your blade. Start with gentle pressure and the finest abrasive that will work for your knife’s condition.
What’s the difference between honing and sharpening?
Honing realigns the edge of your knife without removing material. Sharpening actually grinds away metal to create a new edge. You should hone frequently (even daily) but sharpen only when needed (every few weeks to months).
Conclusion: My Top Pick
After testing all these sharpeners extensively, my top recommendation for most people is the Chef’s Choice 312. It combines ease of use with excellent results, works on all types of knives, and creates an edge that lasts. For those who prefer manual sharpening, the Horl 2 Oak Rolling Sharpener is my pick for its precision and quality.
Remember, the best sharpener is the one you’ll actually use regularly. A simple sharpener that keeps your knives consistently sharp is better than an advanced system that stays in the drawer.
Happy sharpening, and enjoy the smooth, effortless cutting that comes with a truly sharp fillet knife!
