Types of Fillet Knife Sharpeners

Manual Sharpeners

Even without electricity infusion, manual fillet knife sharpeners hold up very well. The reason being, they can be as effective as their electrical counterparts.

Most of them use whetstones to grind beat metal. They also don’t require assistance from angle stabilizers and other devices. Instead, they only need your bare old muscles.

Nevertheless, some people don’t like manual sharpeners because they dislike applying effort.

Electric Sharpeners

On the contrary, most people love electric sharpeners because of their ease of use and speed. They are probably the most convenient sharpeners out there.

However, like any other machine, electric sharpeners aren’t perfect. Most of them produce loud and annoying noise besides reducing the blade’s lifespan. Also, sometimes these sharpeners tend to overheat.

Sharpening Systems

These are guided accuracy devices. Mostly, they comprise grit stones or diamonds, angle adjustment, polish tapes, etc.

They are straightforward to handle and use as well. Nonetheless, knife sharpening systems have several parts. And so, they tend to be somewhat bulky.

Buying Guide


When purchasing, you must consider the size. It may not affect the sharpener’s performance. However, it influences how you store it.

Do you have enough room for a substantial electric sharpener? Or, is your kitchen running low on space? Most manual and stone sharpeners, however, are compact enough to fit in a drawer.

So, always check the dimensions of your target sharpener. Then before purchasing, consider if you have enough kitchen room to store it.


All sharpeners come with some level of grit. Stone sharpeners mostly feature two sides. Electric and manual sharpeners, on the other hand, mostly include at least two settings. When sharpening, the amount of metal taken off the blade determines the level of grit.

A damaged knife with chips or nicks requires a coarse grit. A dull blade without any damages will only require medium grit. And, if refining is all your knife requires, fine grit should do.


Nearly all sharpeners will do the job. But it takes some sharpeners longer to sharpen your edges than others.

Some people don’t mind taking five minutes or so running the knife up and down a whetstone. However, that’s not fun for others.

If you fall under the impatient category, opt for an electric or manual sharpener. With these, it only takes a few passes through the unit. They’ll finish the job, only much quicker.


You’ll find knife sharpeners running from as low as $10. At the same time, high-end models run as high as $150 or more. It’s vital and necessary to examine your budget. After doing so, get yourself the best sharpener in that price range.

Do you intend to use your sharpener every month or week? If yes, opt for a high-end unit with durable materials for longevity.

In the same way, you may only need a knife sharpener to use before or during the holidays. As such, a fairly-priced model should do.

How do I sharpen my fillet knife without a sharpener?

If you urgently need to sharpen your blade and you lack a sharpener, try the following. Use the rough rim or a ceramic cup or mug. Alternatively, use another knife.

What should I use to clean my ceramic rod?

I would recommend using an eraser block to eliminate any metal detriment from the rod.

Should I do anything else after sharpening the blade?

After sharpening your knife, polish it using stropping leather or fine sandpaper. The step is voluntary.

Which sharpener has the best size?

Most manual and electric knife sharpeners are compact to fit comfortably on your counter. When not in use, store them in a drawer.

Do you pull or push when sharpening?

You can do either or combine both strokes. But for edge refinement, I would recommend the push stroke.

What is the best material for a knife sharpener?

A sharpener with ceramic as the abrasive is effective on steel. But for ceramic knives, consider diamond abrasives.

Which brand makes the best knife sharpener?

Many brands are making great knife sharpeners. However, I believe Chef’sChoice and Work Sharp have the best products.
