Overview

A 9 inch fillet knife from Kershaw with a co-polymer handle, weighing about 3.5 ounces in a black colorway. The category and title agree here: this is a knife, not a sheath, despite fillet knife listings sometimes carrying sheath-related category labels.

At 9 inches overall and 3.5 ounces, this sits in typical fillet knife territory, light enough for repeated cuts through fish without wrist fatigue. The co-polymer handle points to a rubberized or textured synthetic grip rather than wood or bare plastic, which matters most when hands are wet.

  • 9 inch overall length
  • 3.5 ounce weight
  • Co-polymer handle
  • Black colorway

Who it's for

Anglers who clean their own catch and want a dedicated fillet knife with a lightweight, wet-grip handle rather than a general kitchen or hunting knife.

Pros and cons

Pros
  • Light at 3.5 ounces for extended filleting
  • Co-polymer handle for grip when wet
  • 9 inch length suited to fillet work
Cons
  • Blade steel type is not specified in the listing
  • No sheath is listed with this item

Performance notes

The 9 inch length and 3.5 ounce weight are built around control for thin, precise cuts along a fish's spine and skin, and a co-polymer handle is meant to stay grippy when wet, which matters more for a fillet knife than raw blade hardness.
