Know before you buy
Unlike traditional smooth steel rods that simply realign the blade's edge, the diamond-coated surface on this Global steel provides a light abrasive action. This removes a microscopic amount of metal to refine the edge, making it more effective at maintaining sharpness over time.
The oval profile offers a wider contact surface compared to a traditional round rod. This increased surface area makes it easier to maintain a consistent angle while honing, providing more stability as you draw the blade across the steel.
No, this tool is designed specifically for edge maintenance and honing. If your knife has become significantly dull or has chips in the blade, it will require professional sharpening or a dedicated sharpening stone to restore the edge.
For the best results, use the rod daily before or after your cooking sessions. Regular, light honing prevents the edge from rolling and keeps your knives performing at their peak between professional sharpenings.
Yes, this 10-inch diamond steel is suitable for most standard kitchen knives. However, it is particularly well-suited for Global knives and other high-quality stainless steel blades.
