What to Look for in the Best Fish Fillet Knives
So, what should you look for when shopping for a new knife? There are a few important factors to keep in mind before you buy:
With a sharp fish knife, filleting is easy. That’s why the blade sharpness and material is so critical. You need a blade that is both flexible and thin, while keeping its edge so that you don’t have to sharpen it regularly. A full tang blade is a good feature to look for, as it will provide extra strength and balance the knife out well.
A stainless steel blade is best because then you have the added advantage of it being corrosion-resistant.  Fillet knives are in contact with water frequently, so you don’t want your knife to rust away. Another alternative to a stainless steel blade is to look for a blade that has a titanium coating to protect it from rust.
Handle Grip & Comfort
An ergonomic handle is an essential feature of a good boning knife. You want to be able to hold it comfortably, especially if you have a big batch of fish to work your way through. Another critical factor to look for is a non-slip handle so that you can get a firm grip on the knife and reduce the risk of slips and injuries.
Size of the Knife
The size of the knife needs to match the size of the fish that you will be filleting. The best fillet knife shouldn’t be more than 2 inches longer or shorter than the fish for safety and ease of use.
Strength & Durability
You want a fillet knife that’s durable, strong, and built to last for years. The more flexible the blade is, the less likely it will be to break during use. Look for a knife that seems sturdy and is made from high-quality materials. Some brands even offer a warranty, which is an added bonus.
The Rockwell hardness scale is useful for gauging how strong the steel is.  The strongest steels will rank high on the Rockwell hardness scale, with high carbon stainless steel right at the top. So, if you find a knife made from high carbon stainless steel, you’ll know you’ve got a winner.
