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
- Light at 3.5 ounces for extended filleting
- Co-polymer handle for grip when wet
- 9 inch length suited to fillet work
- 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.
