Overview

The Kershaw 1242GEX is a 9 inch fillet knife with a curved stainless steel blade, weighing 3.5 ounces. It is built for cutting through fish along the spine and skin rather than general kitchen use.

Kershaw is a known cutlery maker, and the curved 9 inch blade length puts this knife in the mid to large fillet size range, suited to bigger panfish through modest saltwater species.

  • 9 inch curved fillet blade
  • Stainless steel construction
  • 3.5 ounce weight
  • Kershaw 1242GEX model

Who it's for

Fits anglers filleting fish regularly enough to want a dedicated stainless blade rather than a folding pocket knife. Less suited to someone who only cleans fish occasionally and would get by with a shorter blade.

Pros and cons

Pros
  • 9 inch curved blade suited to mid to large fish
  • Stainless steel resists corrosion
  • Light at 3.5 ounces
Cons
  • No handle grip or sheath details given in the spec

Performance notes

The curved blade profile is meant to follow the contour of a fish's rib cage and skin in one motion, which is the main advantage of a dedicated fillet knife over a straight kitchen blade. Stainless steel resists the corrosion that comes with repeated contact with fish and water.
