SHARPAL 156N Double-Sided Diamond Sharpening Stone – Coarse 325 / Extra-Fine 1200 Grit, Storage Case & Angle Guide

Effortless sharpening with a precision-made surface

The SHARPAL 156N is a robust, double-sided diamond sharpening stone designed to deliver reliable results across a range of blades. Built on a 0.33 inch thick stainless steel base, it uses industrial monocrystalline diamonds that promise a flat, consistent contact area throughout use. This setup is engineered to resist warping and maintain a true edge, even after repeated sharpening sessions in a busy kitchen, workshop, or outdoor kitchen setup.

Whether you’re freshening a kitchen knife or reviving a workshop blade, this tool is designed to be a practical, ready-to-work companion right out of the box. Its compact 6 inch by 2.5 inch footprint fits easily into drawers or tool kits, helping you keep blades safe and sharp without added bulk.

Dual grit for versatile edge care

The 156N combines two grits in one: a coarse 325 grit (45 microns) for quick edge setting and an extra-fine 1200 grit (12 microns) for honing. This pairing supports both fast edge creation and refine finishing, making it suitable for a wide array of hard materials, including high-speed steel, carbide, ceramic, and cubic boron nitride tools. An advantage for daily users is the ability to sharpen dry, avoiding the need for oil or water and minimizing mess.

• Coarse grit accelerates edge establishment, helping blades feel sharper faster.
• Extra-fine grit finishes with a smoother edge for immediate use.
• Works dry, reducing prep time and cleanup.

Precision and flatness you can trust

SHARPAL’s MirrorFlat technology guarantees a consistently flat surface that maintains even contact with blades. This helps reduce uneven wear and ensures each stroke contributes to a uniform edge. The result is a dependable, repeatable sharpening experience, whether you’re fine-tuning a chef’s knife or a daily-use tool.

Bonus kit for easy setup and accurate angles

Included in the package is a sturdy storage box with a non-slip rubber pad that doubles as a stable stone base. A built-in sharpening angle guide provides four universal angles—14°, 17°, 20°, and 25°—so you can pursue consistent edge geometry across tools. An instruction manual is tucked inside the packaging for quick setup and reference.

• Non-slip base helps keep the stone in place during use.
• Angle guide supports multiple common blade geometries for consistency.

SHARPAL stands behind its craft with a 3-year commitment and after-sales service. Headquartered in California with international offices, the brand emphasizes durability and performance through thorough testing.
