Bubba Blade Flex Fillet Knife

In this article, you will find a comprehensive review of one of our top choices when it comes to fillet knives—the Bubba Blade Flex Fillet Knife. This knife has a nine-inch flexible blade that is great for gutting, descaling, and filleting medium- to large-size fish.


The Bubba Blade Flex Fillet Knife offers the following:

  • 8CR13MOV Stainless Steel

And what the heck is 8CR13MOV Stainless Steel? Well, trust me it’s good. It relates to the quality of steel used. This stuff comes from China but it’s still good. No offense intended to my Chinese friends but you know what I mean. It signifies that it’s tough, rust resistant and keeps a good, sharp edge.

As mentioned, the blade material is one crucial aspect when choosing a great fillet knife. It doesn’t matter if you fish in saltwater or freshwater, you must choose a knife with a blade that is made with non-corrosive material.

With this knife’s exceptionally durable stainless steel edge, you can expect good edge retention and ease of sharpening whenever needed.

  • Tin-Coated, Non-Stick Blade

The sharp blade has a non-stick feature that makes every single slice clean, which means that you don’t have to wipe the blade between slices. This is because the blade is coated with Ti-Nitride, making it resistant to corrosion, even when used frequently in both saltwater and freshwater environments.

  • Hand-Sharpened Quality

The blade of each Bubba Blade Flex Fillet Knife is sharpened by hand, which ensures it is as sharp as a scalpel. This makes it more than capable of filleting different kinds of fish.

  • Ergonomic, Slip-Proof Grip

The handle can make or break a fillet knife. It is one of the two major parts of a knife that you should never overlook. The Bubba Blade Flex Fillet Knife has a trigger-shape, non-slip handle that ensures a solid hold even when things get slimy and wet.

This fillet knife has a handle that is made with a thermoplastic polymer that is wrapped with synthetic rubber, giving you a sticky, strong grip. For total control and to avoid accidents, this knife also comes with thumb and finger pads.

  • Moderate Flexibility

With a knife that is slightly flexible, you can bend the blade moderately as you slice through the fish’s backbone, giving you a clean and close fillet every time. Fortunately, this can be done easily with the help of this knife’s flexible blade.

  • 56 to 58 Rockwell Hardness Rating

The Rockwell Hardness Rating or HRC rating of the Bubba Blade Flex Fillet Knife is between 56 and 58, which means that the stainless steel used to craft this piece is of the highest quality.

  • Lanyard Hole

The knife has a lanyard hole in the handle, allowing you to attach it on your belt. Make sure to use a safety knife cover when you do.

Cons & Pros


  • Has a blade that keeps its sharpness
  • Non-stick finish that also prevents corrosion
  • Easy to sharpen
  • Comes with safety features
  • Full-tang construction ensures durability
  • Does not slip easily


  • Not ideal for filleting small fish

Summary of the Features

The Bubba Blade Flex Fillet Knife is a nine-inch fillet knife with a hand-sharpened, tin-coated, stainless steel blade. Like with most high-quality fillet knives, this one is built with a full-tang design, ensuring durability and top performance for years to come.

With your safety in mind, this ergonomically designed fillet knife is also equipped with a slip-proof handle as well as thumb and finger pads. All in all, it measures 15 inches, with a nine-inch blade and a six-inch handle. This makes it perfect for filleting medium to large fish.

Comparison With Another Fillet Knife

Let us compare the Bubba Blade Flex Fillet Knife with the Victorinox Cutlery Straight Fillet Fishing Knife to see how it fares. First, the size difference of the two is just an inch, making both of them ideal for medium- to large-sized fish and not that great for filleting a small catch.

Both knives use high-carbon stainless steel blades, but Bubba Blade Flex is coated with non-stick Ti-Nitride while Victorinox is not. The non-stick coating allows continuous slicing without needing to wipe or clean the blade. Plus, it keeps corrosion at bay, regardless if the knife is used frequently for saltwater fishing.

Regarding the sharpness, both have exceptional qualities. However, the handle of the Victorinox fillet knife is ideal for home use rather than for outdoor adventures. Bubba Blade’s thermoplastic polymer handle is rugged and has a synthetic rubber coating, which makes this knife virtually slip-proof, thus keeping the user safe and the knife secure even when you are using it in the most awkward of situations, including cold weather for the fishing enthusiasts.

The Final Say

If you are looking for a high-quality fillet knife, you can check out Bubba Blade Flex Fillet Knife. With a full-tang construction, you can expect durability since it is made from one-piece steel all through its handle. This does not only mean a hard-wearing knife, but also a well-balanced one that has a nice heft, which makes it ideal for any cutting needs.

Nevertheless, do not expect the edge to stay sharp if you are using it to cut fishing lines, ropes, and other similar things. You can easily run it through a knife sharpener or knife steel though, and the blade will be as sharp as new.

The handle, on the other hand, is comfortable to hold, thanks to its unique trigger shape. Its main material is coated with synthetic rubber that turns sticky when wet, ensuring less slippage. The included thumb and finger pads help, too.

All in all, the Bubba Blade Flex Fillet Knife is definitely one of the best fillet knives you can buy. Undoubtedly, it would also help level up your food preparation skills in no time.
