To sharpen a flexible BUBBA fillet blade without damaging its protective coating, lock your sharpening angle at 19 degrees for manual fillet knives, use light, even strokes on a fine stone, and avoid abrasive pull-through carbide scrapers that strip steel and scratch finishes. Using the Ultra Knife Sharpener keeps edges consistent on everything from a 6" Ultra Flex to a 9" Stiff Fillet.
Match Your Sharpening Angle to the Blade
Fillet blades rely on a keen, thin edge to glide along delicate Walleye ribs and skin. Using too steep an angle creates a thick, wedging edge, while guessing freehand often rounds the tip or scuffs the blade coating.
- 19-Degree Position (Fillet & Fine Slicing): Ideal for the 7" Tapered Flex, 6" Ultra Flex, and 9" Stiff Fillet. The Ultra Knife Sharpener locks into a 19-degree guide with a suction-grip base that sticks right to your cleaning table.
- 26-Degree Position (Heavy Utility & Camp Blades): Best for rugged everyday work on a Sculpin Pocket Knife that cuts rope, packaging, and tough camp materials.
Step-by-Step Touch-Up Routine
- Clean & Dry First: Wash off fish slime, scales, and oil before touching any stone so residue does not glaze the abrasive surface.
- Choose Medium vs. Fine Grit: Start on the medium 400-grit side of the Ultra Knife Sharpener only if the edge is noticeably dull, then finish on the fine 180-grit stone for a polished, hair-splitting bite.
- Support Flexible Tips: When sharpening a thin 6" Ultra Flex, use light pressure so the blade does not bow away from the guide.
- Swap Electric Blades Instead of Grinding Teeth: Reciprocating serrated blades on the Pro Series Cordless Electric Fillet Knife and Lithium Ion Cordless Fillet Knife are not meant for flat stones. Once worn after heavy seasons, snap in fresh Electric Fillet Knife Replacement Blades or Bubba Replacement Blades E-Glide.
Frequently Asked Questions
Does normal blade dulling fall under BUBBA's warranty?
No. Like all cutlery, normal wear and tear—including a dull or chipped edge from use or scratched blade coating—is regular maintenance rather than a manufacturing defect.
