Overview
The OUTDOOR RFU-50C is a fillet knife listed at 10.9 inches overall and 4.1 ounces, paired with a fiberglass reinforced nylon sheath that carries a pocket clip for belt storage.
The material spec on file, fiberglass reinforced nylon, describes the sheath rather than the blade steel, which the listing does not break out separately. Buyers wanting a specific blade steel grade should look elsewhere for that detail, since it is not stated here.

Who it's for
Anglers who want a lightweight fillet knife they can clip to a belt or bag for boat or dock use. Less useful for anyone needing a documented blade steel spec before buying.
