  • Brand: Bubba
  • Model Name: BB1-7F
  • Blade Length: 7 inches
  • Blade Style: Tapered Flex
  • Handle Material: Non-slip grip

The Bubba BB1-7F stands out with its iconic red and gray non-slip grip handle, 7 inch ti-nitride coated high carbon stainless steel blade, and convenient belt sheath. It’s designed in the USA by Bubba Blade, a leading maker of fishing knives and tools.

Features and Benefits

  • Razor Sharp Blade: The 7 inch tapered blade is crafted from ti-nitride coated 8Cr13MoV stainless steel hardened to 56+ HRC. It retains its factory edge very well.

  • Ideal Flexibility: The tapered flex blade moves easily around bones and fins for precise, effortless filleting. It has enough stiffness to cut through meat and skin.

  • Non-Slip Grip: The signature grip handle provides outstanding control when wet or bloody. The trigger grip adds further security and comfort.

  • Corrosion Resistance: The ti-nitride coating protects the blade from rust and corrosion. It’s easy to clean after use.

  • Convenient Sheath: The secure belt sheath keeps the knife close at hand while protecting the blade.

Performance and Quality

In testing, the Bubba BB1-7F proves itself as a rugged and versatile fillet knife. The razor sharp blade and tapered flex design make short work of filleting everything from delicate panfish to meaty salmon. It handles both freshwater and saltwater species with ease.

The non-slip grip gives a very confident, controlled feel even when wet. While flexible, the blade is stiff enough to cut through fibrous tissue and skin. The spine safety guards protect your fingers while filleting.

Fit and finish is excellent. The materials feel durable and high grade. Even after heavy use, the knife retains its factory edge and shows minimal wear. For anglers who take care of their gear, this knife should provide years of service.

Usage and Maintenance

The Bubba BB1-7F truly excels as an all-around fillet knife for fish of any size. The thin, tapered blade allows for precision cuts and is ideal for removing fillets from the ribs. It works equally well for panfish, walleye, salmon, and saltwater species.

Keep the blade sharp with a honing steel, ceramic rod, or electric sharpener. Avoid using the dishwasher to prevent damage to the handle and blade. Lubricate the blade to prevent corrosion, especially after saltwater use.

Overall the knife requires little maintenance beyond periodic sharpening and cleaning.
