Victorinox Fibrox 6 in. Stiff Wide Boning Knife Click To View Larger Image

Victorinox Fibrox Pro 6-inch Straight Stiff Wide Boning Knife

This 6-inch stiff, wide boning knife is built for strength and stability. Its straight edge breaks through stubborn joints, trims around bones and cartilage, and slices individual chops from a loin, which covers much of the work at a butcher block.

The rigid blade does not bow when you lean on it, so the cut goes where you aim it. That makes it a good knife for beef and pork, where the bones are heavy and the connective tissue is tough. It can also be used as a fillet knife on firm, thick fish.

Keep the point against the bone and draw the knife toward you in long, steady strokes. On a pork loin, run the edge down the chine and along the ribs, then turn the knife to cut chops of even thickness.

For the same blade with a wood handle, choose the Hardwood 6-inch Straight Stiff Wide Boning Knife. The extra-wide 6-inch adds more height, and the 5-inch is the shorter version. Our Kitchen Knife Shapes guide explains stiff and flexible boning blades.

    Choosing a Victorinox Boning Knife

    Keeping the Edge

    Victorinox steel at this hardness takes a fine edge quickly and responds well to honing. A few light strokes on a honing steel during a work session keep the edge aligned; sharpen on a stone or a guided sharpener when honing no longer brings it back. Our Honing Rod Guide compares regular, fine and polishing cuts, and the Victorinox 12-inch fine cut honing steel suits these blades.


    Care

    • Victorinox rates Fibrox Pro knives dishwasher safe. Washing by hand and drying at once keeps the edge from knocking against other items in the rack.
    • Cut on wood or soft composite boards rather than glass, stone or ceramic.
    • Store in a block, on a magnetic strip or in a sleeve such as the Victorinox Knife Safe for 4-inch to 6-inch Knives, not loose in a drawer.
