Overview
Dexter's DX8F pairs an 8 inch flexible fillet blade with an included sheath, weighing about 3 ounces. It is built for anglers who clean their own catch rather than for general kitchen prep.
Dexter has made fillet knives for fish houses and commercial kitchens for decades, and the DX8F follows that pattern with a narrow, flexible blade meant to follow the bone line rather than chop through it. The included sheath covers the edge for storage and transport.
- 8 inch blade
- Includes sheath
- 3 ounces

Who it's for
Anglers and anyone cleaning fish who wants a dedicated flexible fillet blade with a carry sheath. Not intended as an all purpose kitchen knife.
Pros and cons
- 8 inch blade sized for filleting
- Comes with a sheath
- Light at about 3 ounces
- Flexible blade is not suited to heavier cutting jobs
- Handle material not specified in the listing
Performance notes
A flexible fillet blade is meant to bend and trace along bone and skin, which is what sets it apart from a stiff chef's or utility knife when working a fish.
