SHARPAL Diamond Sharpening Stone 8 x 3 in. — 325/1200 Grit Double-Sided, Stainless Base for Dry Sharpening

The SHARPAL 162N is an 8" x 3" double-sided diamond sharpening stone with 325 coarse and 1200 extra-fine grits for fast, durable, and dry sharpening of knives and hard tools.

Built for homeowners, chefs, hobbyists and tradespeople, this SHARPAL stone combines industrial monocrystalline diamonds electroplated on a thick stainless-steel plate with the company's MirrorFlat surface finish. The unit measures 8 in. by 3 in., mounts in an included storage box that doubles as a base, and delivers consistent flatness and long-lasting cutting performance without oil or water.

How quickly will it restore a dull edge?

The coarse 325-grit side (about 45 micron) resets and reshapes edges much faster than traditional oil or water stones, letting you re-establish bevels and remove nicks quickly. Follow with the 1200-grit side (about 12 micron) to refine and polish the edge for everyday cutting tasks.

• 325 grit for heavy material removal and edge setting.
• 1200 grit for honing and fine polishing.
• Electroplated diamonds cut faster than bonded stones.
• Sharpen dry — no oil or water needed.

Will it stay flat and last through heavy use?

SHARPAL’s MirrorFlat technology and a 0.35" stainless-steel base provide a rigid, super-flat surface that resists wear and maintains even contact across the blade. Unlike softer oil or water stones that cup or groove, this diamond plate retains shape for longer life and predictable sharpening results.

• 0.35 inch stainless-steel base for rigidity and stability.
• MirrorFlat finish reduces uneven wear.
• Industrial monocrystalline diamonds bonded to the plate for durability.
• Designed for repeated heavy use without significant flattening.

What kinds of blades and materials can I sharpen with it?

The SHARPAL 162N is suitable for a wide range of hard materials — including high-speed steels, carbide, ceramic and cubic boron nitride — so it works for kitchen knives, pocket knives, chisels and many hardened cutting tools. Because sharpening is done dry, it’s convenient for bench or field use.

• Effective on HSS, carbide, ceramic, CBN and common stainless steels.
• Safe for small tools, knives and beveled edges.
• Dry sharpening removes need for messy lubricants.
• Use coarse side first, then finish on extra-fine side.

How do I use the included accessories for best results?

The package includes a storage box that doubles as a non-slip base, a rubber pad to stabilize the stone, an integrated angle guide with four common angles (14°, 17°, 20°, 25°), and printed instructions — making setup simple for accurate, repeatable sharpening. The angle guide helps maintain consistent bevels while working across both grits.

• Storage box converts into a stone base for bench stability.
• Non-slip rubber pad prevents movement during sharpening.
• Angle guide provides 14°, 17°, 20° and 25° preset guides.
• Instruction manual outlines coarse-to-fine technique steps.

Who is this for? The SHARPAL 162N is aimed at cooks, outdoor enthusiasts, woodworkers and tool users who need a rugged, fast-cutting sharpening solution that keeps its flatness. If you want an all-purpose, low-maintenance diamond stone that works dry, handles hard steels and includes practical accessories for consistent angles, this model fits those needs. Backed by SHARPAL’s international support and a three-year commitment, it’s a practical upgrade for anyone seeking reliable, long-lasting sharpening performance.
