Our verdict

A 7 inch fillet knife with a super polymer grip and an included sheath, sized for typical panfish and mid-size freshwater cleaning rather than large saltwater species.

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

Pros
  • Sheath included for safe storage
  • Light at 6.4 ounces for extended use
  • Grip designed for wet handling
Cons
  • 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.
