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.

Performance notes
