Dual Grit Diamond Sharpening Stone 400/1000

Our premium diamond sharpening stone is engineered to cut fast, stay perfectly flat, and deliver repeatable, professional-level results every time you sharpen. With a 400 grit side for rapid edge correction and a 1000 grit side for refining and smoothing, it takes your blade from dull and damaged to razor-sharp in minutes. Whether you’re restoring a neglected knife or dialing in a fresh edge, this stone gives you total control over the sharpening process.

Sized at 7 1/16" × 2 3/8" × 1 3/16" (180mm × 60mm × 8mm), it provides a generous working surface that feels solid and stable without being bulky or awkward to handle. The industrial-grade diamond coating bites immediately into even hard steels, removing material quickly while maintaining consistent cutting performance over time. Unlike softer stones that wear unevenly, this stone stays flat and reliable session after session.

This stone is ideal for:

• Repairing damaged or rolled edges

• Reprofiling dull or poorly shaped knives

• Establishing a clean, sharp bevel

• Preparing your edge for finer stones and stropping

Unlike traditional water stones, diamond stones don’t dish, don’t glaze, and don’t slow down. You get aggressive, predictable cutting power every time you sharpen, making results easier and faster to achieve.

Fast. Flat. Precise.
This is the foundation of a truly sharp knife.
