Lansky knife sharpening kit — 4-Stone Deluxe Diamond System, clamp guide & selectable angles

The Lansky 4-Stone Deluxe Diamond System is a controlled-angle, portable sharpening kit that restores and refines knife edges with four diamond hones for consistent, repeatable results.

This compact system combines a clamp-style guide, selectable sharpening angles, and four color-coded diamond stones so you can repair, shape, and polish blades for kitchen, outdoor, or hobby use. The kit’s molded carry case and finger-grooved stone holders keep components organized for travel or bench work, while the range of grit levels covers everything from edge repair to final honing.

How does the angle selector make sharpening easier?

The angle selector lets you lock the blade at one of four precise angles so every pass follows the same geometry. Consistent angles reduce guessing and produce repeatable, predictable edges whether you’re re-profiling a dull blade or putting the finishing bevel on a pocketknife.

• Four preset angles: 17°, 20°, 25°, 30° to suit different blade types
• Rigid clamp holds blades securely during guided strokes
• Guide rods ensure even contact across each pass

Which stones are included and what do they do?

The kit includes four diamond hones ranging from extra-coarse to fine for a full sharpening progression. Start with the coarser grits to remove nicks or re-profile, then move to medium and fine stones for edge refinement and smoother cutting performance.

• Extra-coarse and coarse for rebuilding or removing damaged metal
• Medium for shaping and establishing the primary bevel
• Fine for polishing and final edge refinement

What safety and convenience features are built in?

Practical design elements make sharpening safer and neater: finger-grooved stone holders improve grip, a soft-bristle brush cleans debris, and the custom molded case stores everything for secure transport. The clamp design leaves the blade exposed only as much as needed, helping control movement and minimizing hand contact with the edge.

• Finger-grooved holders for stable, non-slip stone handling
• Soft-bristle brush for clearing metal filings between grits
• Custom carrying case keeps stones, rods, and clamp organized

How portable and durable is the Lansky 4-Stone system?

This system is built for bench use and field portability: diamond stones resist wear and the molded case protects components during transport. The precision-engineered clamp and hardened guide rods are designed to stand up to repeated use and maintain alignment.

• Diamond hones provide long-lasting abrasive performance
• Sturdy clamp and guide rods maintain consistent angles over time
• Compact case fits in toolboxes, backpacks, or kitchen drawers

Who this is for: The Lansky 4-Stone Deluxe Diamond System is ideal for home cooks who want sharper kitchen knives, outdoorsmen and hobbyists who maintain folding or fixed blades, and anyone who prefers a controlled, repeatable sharpening process over freehand methods. It suits users who need a complete grind-to-polish sequence in a compact, travel-ready kit.
