Buying Guide- Which is The Best Fillet Knife Sharpener?

In choosing the best sharpener for your fillet knife, consumers consider a variety of factors typically. These factors can include:

Quality of Abrasives

To ensure your fillet knife is sharpened properly without causing any damage to its blade, you need to consider the quality of abrasives used. Most sharpeners use 100% diamond abrasives to provide users with razor-sharp edges. Generally, diamond abrasives are hard to beat when it comes to sharpening quality. Other sharpeners boast tungsten carbide or polished ceramic abrasives but are relatively expensive.

Number of Sharpening Stages

Most sharpeners feature between two and three sharpening stages. For models with two stages, you can expect pre-sharpening and honing or polishing stages. Even though sharpeners with a two-stage system is flawlessly functional, units with more stage systems are much better depending on your needs. 


The best sharpener for your fillet knife should at least be backed by relatively good warranty. Most manufacturers offer one to three years of limited warranty against defects. As a precaution, always inquire what your warranty covers prior to making your purchase.

Manual vs Electric

Manual fillet knife sharpeners are easy to use and even safer compared to their electric counterparts. However, most knives especially those with heavily waved edges don’t lend themselves to manual sharpening. Electric sharpeners, on the other hand, provide faster results than manual units. They are also easy to use, offer a lot of conveniences and do more than just sharpening the blades. Most electric sharpeners will even polish your fillet knife. 

Ease of Use

A fillet knife sharpener that is easy to use should at least be accompanied by an adjustable precision angle guide. This is because the guide will automatically position the knife at the perfect angle for accurate sharpening. Make sure the guides can easily handle different angles including 15 degrees. 

Final Verdict

Dull or blunt fillet knives makes it difficult to get the job done and can become a health hazard. As a matter of fact, you are more likely to get cut while using a blunt fillet knife than when using a razor sharp one. Using a dull fillet knife can also ruin your fish. So keep your fillet knife as sharp as possible without damaging its blade by investing in any of these best fillet knife sharpener options.
