The Intermediate / Premium Knife Sharpening Set is designed for intermediate sharpeners who want a premium setup with high-quality stones and accessories. It covers a wide range of knives, from Japanese carbon steel and stainless knives to Western-style blades, and features a full progression of grits to handle everything from dull edges to fine polishing.

All stones, except the #6000 which comes from the Naniwa Traditional line, are from the Naniwa Professional series. These high-tech stones are among the hardest Japanese sharpening stones available, minimizing wear and maximizing lifespan. They sharpen quickly and efficiently, giving experienced users a noticeable difference in speed and control.

What sets these stones apart is their magnesium bonding—unlike traditional resin, it creates a denser surface packed with finely graded abrasive particles. The result? Slower wear, long-lasting flatness, and smoother, more efficient sharpening. Paired with an adjustable stone holder and guide clips, this set ensures a stable, controlled sharpening experience from start to finish.

Products included:

• Naniwa Professional Stone #400 – Prep stage for repairing chips and reshaping the edge.
• Naniwa Professional Stone #1000 – Core sharpening stage.
• Naniwa Professional Stone #3000 – Refining and fine sharpening.
• Naniwa Traditional Stone #6000 – Final polishing stage for a razor-sharp edge.
