Victorinox Forschner 40517 Boning Knife, Black Fibrox Handle, 6 Inch Curved Semi-Stiff Blade. Perfectly suited for accurate cuts, the Victorinox 40517 boning knife is small and lightweight while still providing the high-quality performance you’ve come to expect from Victorinox. At only 6 inches long from tip to handle, the semi-stiff curved blade is small and narrow making it great for separating flesh from fish and working around the small bones of poultry. Stamped construction provides a thinner, lighter blade, and the patented black Fibrox handle is slip-resistant when wet to help you avoid unwanted slips and mistakes. Built to last and proven to perform, the Victorinox 40517 boning knife is an all around excellent addition to any cutlery set.
