Diamond Sharpening Rods

A diamond rod restores an edge faster than ceramic, and Global notes that it will not shatter if it is dropped. The G-38/B is Global’s diamond-coated rod, oval in section, for cooks who want a honing tool that also sharpens when an edge has gone past simple realignment.It suits a busy kitchen where knives see heavy use between sharpenings. The 26 cm length gives a full stroke on chef’s knives and slicers. Because diamond removes metal more quickly than ceramic, it calls for a light hand and only as many strokes as the edge needs.
Diamond or Ceramic?For routine daily honing and a finer finish, Global’s Ceramic Sharpening Rod is the gentler choice. Choose diamond if your knives dull quickly or you want one rod that can bring an edge back without a stone. Fully dull knives are better served by a whetstone or the Global 2-Stage Ceramic Water Sharpener. Learn More

When a regular steel no longer brings an edge back, a diamond rod will, without soaking a stone or learning to hold an angle on one. Diamond is the fastest-cutting rod there is. This F. Dick rod is 600 grit with a solid core, and that construction matters. Diamond pressed into a solid core lasts for years, while hollow rods with an epoxied coating can wear through in six months to a year of regular use.The oval profile puts more of the rod against the blade on each stroke, so it takes fewer strokes, and you can feel the bevel against the rod more clearly. Diamond also works on hard steels that a plain steel rod cannot touch. Its one drawback is a slightly rougher finish, so it is worth following with a few strokes on a ceramic rod such as the Idahone 12-inch Fine Ceramic Sharpening Rod, Black Wood Handle.
Diamond or Steel?For daily upkeep on a knife that is still sharp, a cut steel such as the F. Dick 10-inch Round Fine Cut Sharpening Steel, Red Handle is gentler and removes less metal. Keep the diamond rod for edges that have gone dull. Our Honing Rod Guide covers when each one makes sense. Learn More

Professional-Grade Edge Restoration: The 12-Inch Diamond Standard Is your favorite chef's knife struggling to pass the 'tomato test'? Most traditional honing steels simply realign a folded edge; they don't actually sharpen the blade. The Ultimate Edge 12 in. Oval Diamond Sharpening Rod is the bridge between a basic hone and a full stone-grind. By utilizing high-quality monocrystalline diamonds, this rod actually removes a microscopic amount of steel to recreate a sharp, biting edge on even the hardest alloys. The Engineering of a Perfect Edge At 600 grit, this rod is specifically engineered for 'medium' maintenance. It is aggressive enough to sharpen a dull blade that has lost its utility, yet fine enough to leave a smooth, refined finish that excels in professional environments. The 12-inch length provides the necessary travel for large 8-inch to 10-inch chef knives, ensuring a single, fluid stroke from heel to tip. Why the Oval Profile Matters Unlike traditional round rods that offer a narrow point of contact, the Oval shape of the Ultimate Edge rod provides a wider surface area. This increases the contact between the blade and the diamond abrasive, giving you more control, reducing the time spent sharpening, and ensuring a more consistent angle across the entire length of your knife.
