Diamond Hone

The Diamond Hone by Lansky Sharpeners is a precision sharpening stone engineered for users of the Lansky Controlled Angle Sharpening System who demand fast, aggressive edge restoration on modern tool steels. Whether you're maintaining tactical knives, hunting blades, or utility cutlery, the Diamond Hone delivers superior cutting performance compared to traditional whetstones or pull-through sharpeners. This stone is purpose-built for serious edge work where consistency and speed matter.

Diamond-coated abrasives are the hardest sharpening medium available, making them ideal for wear-resistant stainless steels and high-carbon tool steels that resist conventional ceramic or oil stone methods. The Diamond Hone integrates seamlessly into the Lansky guided system, which locks your knife at a fixed angle—typically 17 to 30 degrees—ensuring repeatable, uniform edge geometry with every stroke. Available in four distinct grits—extra coarse, coarse, medium, and fine—the Diamond Hone lets you progress from heavily damaged or dull edges through to polished, razor-sharp results. The compact 3.25 x 1.05 x 8.05 inch form factor fits easily in the system's honing rod assembly for stable, hands-free operation.

Field professionals, outdoor enthusiasts, and knife collectors benefit most from Diamond Hone stones, especially those working with modern hardened alloys like M390, CPM-S35VN, or D2 steel that wear down softer stones rapidly. Each grit serves a distinct purpose: extra coarse removes chips and major dullness, coarse establishes a new edge, medium refines the burr, and fine polishes for maximum sharpness and edge longevity. The Diamond Hone is compatible exclusively with the Lansky Controlled Angle Sharpening System and cannot be used as a standalone stone. For optimal results, replace worn or glazed stones and store in a dry location.
