The Idahone 12-inch Coarse Ceramic Sharpening Rod is for cooks whose knives have dulled past the point a fine rod or honing steel can recover, but who would rather not set up a whetstone each time an edge fades. Its coarse high-alumina ceramic removes steel faster than Idahone’s fine rods and restores a working edge in a few strokes. The long rod gives a chef’s knife or slicer room to travel its full length without running off the end.
What It Does for Your Knives Coarse ceramic abrasive: Cuts a fresh edge on knives dulled by regular use. A honing steel only straightens a rolled edge. Measured metal removal: The grit is somewhat finer than the coarse rods in Idahone’s V-type sharpeners, so the rod reworks an edge without the heavy stock removal of a sharpening system’s first stage. Long working surface: Accommodates 10-inch chef’s knives and slicers, so each stroke covers the edge from heel to tip. Wood handle with hanging ring: Provides a secure grip for steady strokes and keeps the rod within reach at the prep station.
Using the Coarse and Fine Rods Together The coarse rod does the corrective work, and a fine rod refines the result. Cooks who keep both on hand use the coarse rod when a knife no longer responds to honing, then finish on the Idahone 12-inch Fine Ceramic Sharpening Rod for a smoother, more refined edge. For routine maintenance of a knife that is still sharp, the fine rod alone is the better choice because it removes less steel. Learn More

The Idahone 12-inch Fine Ceramic Sharpening Rod is for cooks who rely on long knives and want to keep them sharp between full sharpenings. A honing steel only pushes a rolled edge back into line. This high-alumina ceramic rod removes a small amount of steel with each stroke, so it sharpens and polishes the edge at the same time. Its finish is comparable to a fine Japanese whetstone, which makes it a maintenance tool between full sharpenings rather than a substitute for them.
What It Does for Your Knives Long working surface: Gives 10-inch chef’s knives, slicers and sujihiki room for a full stroke from heel to tip, so the entire edge receives even contact. Fine ceramic abrasive: Refreshes a working edge in a few light strokes and leaves a smooth, polished finish. Suited to harder steels: Because the rod abrades the edge rather than bending it, it suits the harder steels of many Japanese knives, which tend to wear or chip rather than roll. Fewer whetstone sessions: Regular use keeps an edge in service longer, so full sharpenings are needed less often.

The Victorinox 12-inch oval diamond sharpening steel is a 600 grit steel with a hollow rod coated in diamond. Diamond removes metal, so this steel sharpens a dull edge rather than only realigning it.The oval shape gives more contact between the steel and the edge of the blade on each stroke. The black nylon handle is non-slip and comfortable in either hand. It is made in the USA.Use light pressure; diamond cuts quickly, and a few strokes on each side are usually enough. Follow with a fine cut steel or a ceramic rod to smooth the edge.Rinse the rod and wipe it dry after use to keep metal filings from clogging the diamond surface. Never use oil on a diamond steel.For a round, solid-core diamond rod, see the Victorinox 12-inch Round Solid Core Diamond Steel. For daily honing after sharpening, the Victorinox 12-inch Fine Cut Honing Steel. Our Honing Rod Guide explains diamond steels. Learn More

The Idahone 12-inch Fine Ceramic Sharpening Rod is for cooks who maintain a full knife block, from paring knives to long slicers, and want one rod that serves all of them. A honing steel only pushes a rolled edge back into line. This high-alumina ceramic rod removes a small amount of steel, so it sharpens and polishes the edge at the same time. Its finish is comparable to a fine Japanese whetstone, which makes it a maintenance tool between full sharpenings rather than a substitute for them.
What It Does for Your Knives Long working surface: Accommodates 10-inch chef’s knives and slicers as readily as short knives, so one rod covers the whole block. Fine ceramic abrasive: Refreshes a working edge in a few light strokes and leaves a smooth, polished finish. Suited to Japanese and Western knives: Because the rod abrades the edge rather than bending it, it maintains softer German steels and the harder steels of many Japanese knives, which tend to wear or chip rather than roll. Natural maple handle with hanging ring: Provides a secure grip for steady strokes and keeps the rod within reach at the prep station.
Other Sizes and Grits The same rod is available in a shorter length as the Idahone 10-inch Fine Ceramic Sharpening Rod, Hard Rock Maple Handle, and with a black handle as the Idahone 12-inch Fine Ceramic Sharpening Rod, Black Wood Handle. When a knife no longer responds to the fine rod, the Idahone 12-inch Coarse Ceramic Sharpening Rod removes steel faster to restore the edge, and the fine rod then refines it. Learn More
