The Powerhouse for Serious Butchery When the job calls for power and leverage, the Victorinox Fibrox 6-inch Stiff Boning Knife is the only tool you need. While flexible knives excel at delicate work, this rigid blade is engineered for breaking down large primal cuts of beef, pork, and venison with unwavering control and confidence. The foundation of its performance is the completely rigid, straight blade. This design prevents the knife from flexing or bending as you push through tough cartilage, dense muscle, and challenging joints. It gives you the power to make deep, precise cuts with maximum force and minimal effort, ensuring you can separate bone and muscle cleanly and efficiently. The sharp, pointed tip is perfect for piercing thick hides and initiating cuts with surgical accuracy. Paired with Victorinox's legendary non-slip Fibrox Pro handle, you get a secure, comfortable grip that won’t fail you, even during the most demanding butchering tasks. Now bundled with a durable leather sheath, this Swiss-made workhorse is built to provide a lifetime of reliable performance for hunters, butchers, and serious home cooks. Learn More

This set pairs the Victorinox Fibrox Pro 6-inch Curved Flexible Boning Knife with the Victorinox leather sheath made for 6-inch blades, so the knife can travel on a belt or in a tackle box or knife roll with its edge covered.The knife’s curved, flexible blade follows a bone or slips under a skin, which suits filleting and skinning fish, breaking down poultry and small game, and trimming fat and sinew. Like any flexible blade, it gives up some edge retention, so bring a steel for long sessions. The sheath keeps the thin edge from contact with other gear and protects your hand when you reach into a bag.

The Victorinox 8-inch curved breaking knife is designed for breaking the primal cuts out of a hanging side of beef, and it is just as useful for dressing out wild game such as deer and elk.It is also my choice of knife for filleting large saltwater fish. The blade is semi-flexible, so you can feel the fish bones without cutting through them, and the shape makes it easy to remove fins and slice around the gill plates. On a yellowtail or a large rockfish, the curve follows the frame from head to tail in long, controlled strokes.In the meat room, use the point to open the seams between muscles and the curved belly to draw through them. The 8-inch length suits sub-primals and game, and the Fibrox Pro handle stays secure in wet, cold conditions.For the longer version, see the Fibrox Pro 10-inch Curved Breaking Knife. With a wood handle, the same blade is the Hardwood 8-inch Curved Breaking Knife, and the yellow-handled version adds a high-visibility handle. Browse all Victorinox breaking knives. Learn More

A long, flexible blade earns its place when a cut calls for long, even strokes. The curve of the Victorinox Fibrox Pro 6-inch Curved Flexible Boning Knife lets the blade glide along a bone or under a skin, so it works for skinning and filleting fish as well as breaking down poultry and small game. Victorinox designs it for trimming fat and sinew.Because the blade flexes, it follows the contour of a bone closely and leaves less meat behind. That flexibility costs some edge retention, so plan to hone it regularly and choose a semi-stiff blade for heavier work. For carrying it to a lake or a hunting camp, the same knife is sold with a sheath as the Victorinox Fibrox Pro 6-inch Curved Flexible Boning Knife with Leather Sheath.
Which 6-inch Boning Knife?The Victorinox Fibrox Pro 6-inch Curved Semi-Stiff Boning Knife, our best-selling all-purpose boning knife, keeps this length with a firmer blade. For smaller birds and tighter joints, the Victorinox Fibrox Pro 5-inch Curved Flexible Boning Knife gives the same flex in a shorter blade.Our Kitchen Knife Shapes guide explains boning knife flex.

Silver skin, chicken thighs and small fish all call for a blade that bends with the work. The Victorinox Fibrox Pro 5-inch Curved Flexible Boning Knife has a thin, narrow blade with a flexible spine, so it follows a curved bone closely and slips under a membrane without cutting into the meat beneath. Victorinox designs it for trimming fat and sinew as much as for boning.In our experience, a flexible blade gives up some edge retention, so it needs a steel more frequently than a stiffer knife. For heavy, repetitive boning, the semi-stiff version holds up better. The textured Fibrox Pro handle stays secure when your hands are wet.
Flexible or Semi-Stiff?The Victorinox Fibrox Pro 5-inch Curved Semi-Stiff Boning Knife has the same length with a firmer blade for poultry processing and heavier cuts. If you need more reach, the Victorinox Fibrox Pro 6-inch Curved Flexible Boning Knife offers the same flex in a longer blade, and the Victorinox Hardwood 5-inch Curved Flexible Boning Knife pairs this blade shape with a wooden handle.Our Kitchen Knife Shapes guide explains boning knife flex.

About half the people who order this knife from us work in meat and poultry processing. The other half are home cooks who break down their own chickens. The Victorinox Fibrox Pro Curved Semi-Stiff Boning Knife has a short, narrow blade that follows the frame of a bird and enough backbone to push through cartilage at the joints. Customers rarely exchange it for another size or flex, so it is a sound first boning knife for anyone unsure where to start.
Close Work on Poultry and Smaller CutsThe curve keeps the edge against the bone as you separate a thigh from the carcass or lift breast meat off the keel, so less meat stays on the frame. The narrow blade turns easily inside a joint, which suits poultry and smaller cuts of pork and lamb. Semi-stiff sits between Victorinox’s flexible and stiff blades. It cuts through connective tissue without bowing and gives a little where the bone changes direction. On a long shift, the textured Fibrox Pro handle matters as much as the blade, since it stays secure in wet or greasy hands.

The curved, semi-stiff blade handles anything from frenching lamb chops to breaking down a chicken, with enough reach for larger cuts such as a pork shoulder. It is as useful on a fishing trip or for dressing a deer as it is in the kitchen, and precise enough to lift silver skin from a leg of veal.A semi-stiff blade stays on line along a bone and still gives a little around joints, which is why it covers so much ground. The textured Fibrox Pro handle keeps a secure grip through a long session.
Shorter or More Flexible?For close work on poultry and small cuts, the Victorinox Fibrox Pro 5-inch Curved Semi-Stiff Boning Knife is easier to control.
