Dexter SG133-8EG Fillet Knife

Overview

The Dexter SG133-8EG is an 8-inch carbon steel fillet knife weighing 4.8 ounces, model number 24902 in Dexter's lineup. It's a single-blade knife built for filleting fish rather than a multi-piece knife set.

Dexter-Russell is a long-running commercial cutlery maker, and the SG133-8EG carries the high carbon steel construction the brand is known for in its fillet and boning knives, which takes a sharp edge and is meant to be maintained with routine honing. At 8 inches the blade suits mid-size to larger fish where a longer, flexible edge helps follow the bone line in one pass. The category listing calls it a sheath, but the title, model number and specs all describe the knife itself, not a sheath.

• 8 inch carbon steel blade
• 4.8 ounce weight
• 14 inch overall length

Who it's for

Anglers and anyone processing their own catch who wants a dedicated fillet blade rather than a folding or general-purpose knife. Less suited to someone who only cleans small panfish occasionally, where a shorter blade is easier to control.

Pros and cons

Performance notes

Carbon steel takes and holds a fine edge better than most stainless alternatives, which matters for a filleting task that depends on a clean, thin cut along the bone. The tradeoff is that carbon steel needs to be dried and lightly oiled after use to avoid rust, unlike a stainless blade.
