Sharpening Stones
Sharpening stones are the foundation of every edge — the abrasive surface that sets the bevel, refines the scratch pattern, and determines how a blade performs in the cut. DLT Trading stocks sharpening stones across every major type and grit level, from coarse diamond plates for damaged edges and reprofiling work through ultra-fine natural Arkansas stones for polished finishing. The right stone depends on the steel you're sharpening, the edge geometry you're building, and whether you prefer a fast-cutting slurry or a low-maintenance dry surface.
Water Stones, Oil Stones, and Diamond Sharpening Stones
Water stones cut fast and produce a sharpening slurry as the binder breaks down, exposing fresh abrasive continuously during the stroke. That speed makes them the preferred choice for routine maintenance and kitchen knife work, though they wear faster than other stone types and require periodic flattening to maintain a true surface. Oil stones — including natural Arkansas novaculite and synthetic aluminum oxide — cut slower but produce exceptionally refined edges with minimal stone wear. Arkansas stones polish as they sharpen, making them ideal as a finishing step after coarser work on synthetic or diamond abrasives. Diamond sharpening stones use industrial-grade diamond particles bonded to a steel plate, delivering the most aggressive cut rate of any stone type. They stay flat without maintenance, work dry or with water, and handle the hardest modern blade steels — including high-vanadium alloys like S90V and 10V — where softer stone types can struggle to cut efficiently.
Choosing Stones by Grit and Steel Type
Coarse grits (under 400) handle reprofiling and damage repair where significant material removal is required. Medium grits (400–1000) establish clean bevels and are the workhorse range for most sharpening sessions. Fine grits (1000–3000) refine the scratch pattern and produce working edges that balance sharpness with edge retention. Ultra-fine grits (3000 and above) polish the apex for applications where a smooth, low-friction cut matters — kitchen prep, skinning, and slicing tasks. Many of these stones also serve as replacement abrasives for guided sharpening systems from Edge Pro, Lansky, and other platforms. For dedicated bench-mounted freehand sharpening stones, DLT carries a focused selection of full-size flat platforms designed for longer blades and heavier stock removal. Finish any stone progression with a leather strop loaded with sharpening compound to remove the burr and refine the apex before the blade goes back to work.
