Choosing a Victorinox Boning Knife
Narrow blades turn tightly around joints; wide blades add stability and leave more steel for resharpening. Our Kitchen Knife Shapes guide explains each shape, and the full range is in our Victorinox boning knives category.
| Blade | How it behaves | Typical jobs | Example |
|---|---|---|---|
| Stiff, straight | Holds a straight line and resists bending | Beef and pork joints, cartilage, chops | Fibrox Pro 6-inch Stiff Wide |
| Stiff, curved and wide | Rigid blade with a sweep that follows the bone | Larger cuts, long strokes along ribs and shoulders | Fibrox Pro 6-inch Curved Stiff Wide |
| Semi-stiff, curved | Firm enough to work joints, with a little give along bone | General boning of poultry, pork and beef | Fibrox Pro 6-inch Curved Semi-Stiff |
| Flexible | Bends to trace the shape of the bone | Poultry, fish, silver skin | Fibrox Pro 6-inch Flexible |
| Super flex | The most bend, for working closest to the bone | Long hours of trimming and close boning | Dual Grip 6-inch Curved Super Flex |
Choosing a Handle
Victorinox fits the same Swiss blades to several handles, so a shape you like can be chosen in the grip that suits your work.
| Handle | Material | Care | Who it suits |
|---|---|---|---|
| Black Fibrox Pro | Textured TPE, slip-resistant when wet | Dishwasher safe per Victorinox; hand washing protects the edge | Commercial kitchens, processing rooms and home cooks who want an easy-care grip |
| Colored Fibrox Pro | The same TPE handle in red, blue, yellow or green | Same as black Fibrox Pro | Kitchens that assign knives to food groups under a HACCP color-coding plan, and anyone who wants a knife that is easy to spot |
| Fibrox Pro Dual Grip | Two-component, non-slip handle that supports the hand and wrist | Same as black Fibrox Pro | Cutters who work for hours at a time and want more support for the hand and wrist |
| Hardwood (formerly Rosewood) | Modified maple stained in the traditional rosewood color | Hand wash only | Butchers and cooks who prefer the feel and look of a wood handle |
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.
