Victorinox 10" Round Sharpening Steel 40580 is an effective way to keep your knives sharp. These Victorinox knife accessories are ten inches long and designed with a regular cut for standard blade sharpening. To use these useful sharpening rods, simply draw your knife's edge along the rod at about a 20 degree angle. After a few passes, your Victorinox knife will be revitalized and ready to use! The Victorinox 10 Inch Grooved Steel has been designed with a grooved, regular cut steel, which gives you a smaller contact area between blade and rod, allowing you to put more pressure on the knife's edge with less effort. This knife accessory works quickly too, so you can have a much sharper knife in just a few minutes. At 10 inches long, the sharpening steel is big enough to be used with most of your kitchen knives, though as a good rule of thumb your sharpening steel should be slightly larger than the longest knife you'll be sharpening. Victorinox has also built a polypropylene handle into the sharpening steel, so you can have the utmost control and comfort when you're using the sharpener. An essential knife accessory to keep around your kitchen at all times, the Victorinox 10in Round Grooved Knife Sharpener will keep your knives at their most pointed.
