Summary
A 7-inch narrow flexible fillet knife with a sealed white polypropylene handle, for anglers and home cooks who fillet panfish and other small species. Rinse and dry the high-carbon blade after each use or it will stain.
Strengths
- Narrow flexible blade follows rib bones and suits panfish and other small species.
- Full-tang construction with a sealed slip-resistant handle and finger guard aids control.
- NSF certification supports use in commercial kitchens.
- Lifetime warranty covers defects in materials and workmanship.
- Owners in r/saltwaterfishing, r/Fishing and r/TrueChefKnives threads report decades of use and easy resharpening.
Weaknesses
- High-carbon blade stains or rusts if left wet, so you must rinse and dry after each use.
- Steel is on the softer side, so edge retention is limited and touch-ups are frequent.
- Dexter does not publish the exact alloy or a hardness number.
- Base foodservice version ships as a bare knife without sheath or sharpener.
- One BladeForums report describes frequent sharpening with factory outlet seconds.
