Choose a 7" Tapered Flex for all-around Walleye/Pickerel and trout, a 6" Ultra Flex for delicate Perch and Crappie rib work, and a 9" Stiff Fillet for heavy-boned Northern Pike, Lake Trout, and Pacific Salmon. Matching blade flex to fish size prevents torn fillets and wasted meat.
Side-by-Side Comparison: BUBBA Manual Blade Profiles
Every BUBBA manual fillet knife shares a full-tang stainless steel build, a non-stick blade coating, safety guards, and BUBBA's iconic red non-slip grip. The difference lies in blade geometry and flex:
| Knife Model | Blade Length | Flex Profile | Best Canadian Species |
|---|---|---|---|
| 6" Ultra Flex | 15.2 cm (6 in.) | Extreme Flex / Thin Blade | Yellow Perch, Crappie, Bluegill, Brook Trout |
| 7" Tapered Flex | 17.8 cm (7 in.) | Medium Tapered Flex | Walleye/Pickerel, Smallmouth Bass, Rainbow Trout |
| 9" Stiff Fillet | 22.9 cm (9 in.) | Rigid / 2 mm Spine | Northern Pike, Lake Trout, Chinook & Coho Salmon |
When to Choose Each Profile
7" Tapered Flex: The Canadian All-Rounder
If you only carry one manual knife in your boat or ice sled, make it the 7" Tapered Flex. Weighing just 162 g (5.7 oz) with a 56–58 Rockwell hardness rating, it has enough rigidity near the handle to break through Walleye gill plates while tapering to a forgiving tip for skinning.
6" Ultra Flex: Built for Panfish & Detail Cuts
The 6" Ultra Flex bends effortlessly over tight panfish rib cages without punching through thin skin. It is also the top choice for harvesting Walleye cheeks or trimming silver skin.
9" Stiff Fillet: Power for Heavy Bones
When slicing through Northern Pike Y-bones or big Great Lakes and BC Salmon collars, soft blades wander. The 22.9 cm (9-inch) 9" Stiff Fillet tracks dead straight and doubles as a camp meat-carving blade.
Want All Profiles in One Case?
If you fish multiple species on one trip, the Freshwater Multi-Flex Interchangeable Set bundles a 7" Tapered Flex and 8" Ultra Flex blade in a waterproof case, while the 4-blade Multi-Flex Interchangeable Set adds a 9" Serrated Flex and 9" Stiff blade.
