Overview
KastKing's Fishing Knives-3 is a 7 inch fillet knife with a super polymer grip handle, built for cleaning panfish through mid-size fish and shipped with a matching sheath. At 6.4 ounces it stays light through repeated cuts at the cleaning table.
The listing notes it comes as a knife and sheath set, which matters because a fillet blade left loose in a tackle box dulls fast and risks a cut hand. A 7 inch blade sits in the middle of the fillet size range, long enough for panfish through walleye and bass without the extra flex of a longer blade meant for bigger saltwater fish.
- 7 inch fillet blade
- Super polymer grip handle
- 6.4 ounce weight
- Includes matching sheath
Who it's for
Anglers who clean their own catch at the dock or kitchen counter and want a dedicated blade instead of a kitchen knife. Less suited to anyone targeting large saltwater species that call for a longer, more flexible blade.
Pros and cons
- Sheath included for safe storage
- Light at 6.4 ounces for extended use
- Grip designed for wet handling
- No stated blade steel type
- 7 inch length may be short for larger fish
Performance notes
The super polymer grip is meant to stay usable when wet or slick with fish oil, the common failure point of cheaper handles at the cleaning table. A 7 inch blade gives enough reach for a smooth single pass fillet cut on typical catch sizes without the whip of a longer blade.
