Victorinox Fibrox Pro 6" Boning Knife, Black — Semi-Flexible Stainless Blade, Ergonomic Fibrox Handle

The Victorinox Fibrox Pro 6" Boning Knife is a semi-flexible, professional-grade blade designed to remove meat and fish from bone cleanly and comfortably.

This Swiss-made boning knife pairs a narrow, semi-stiff stainless steel blade with Victorinox’s patented Fibrox handle to deliver balance, control, and reduced hand fatigue. Built for both busy home cooks and demanding professional kitchens, the 6-inch Fibrox Pro boning knife excels at trimming, portioning, and working around joints. It arrives ready for use and is NSF-approved for commercial environments.

How does this knife handle boning and trimming tasks?

The straight, narrow blade tracks closely to bones and joints, letting you separate meat with minimal waste. Its semi-flexible profile offers enough give for curved surfaces while remaining stiff enough for thicker cuts.

• 6-inch semi-flexible stainless steel blade follows contours for precise meat removal
• Sharp edge slices through fat, tendons and small bones without tearing
• Straight blade profile is suited for both fish and medium-to-thicker meats

What makes the Fibrox handle comfortable and safe to use?

Victorinox’s patented Fibrox handle is textured and ergonomically shaped to minimize slipping and wrist strain during repetitive tasks. The design balances the blade to reduce fatigue for long prep sessions.

• Textured, slip-resistant surface improves grip even when wet
• Ergonomic contour reduces hand and wrist fatigue during extended use
• Fit accommodates a wide range of hand sizes for secure control

How should I care for and sharpen this boning knife?

For longest edge life, hand wash and dry immediately; although dishwasher-safe, frequent dishwasher use can dull the blade from contact with other utensils. Hone regularly and sharpen as needed to maintain peak performance.

• Recommended hand wash with soapy cloth and immediate drying
• Hone after every few uses to realign the edge
• Professional sharpening when the edge no longer responds to honing

Yes—this 6" Fibrox Pro boning knife may ship with the international blade marking 5.6203.15 rather than 47519 or 40519. The blade, handle and performance are identical.

• International item number 5.6203.15 corresponds to the 6" Fibrox Pro boning knife
• Same semi-flexible blade and Fibrox handle regardless of blade marking
