MADE OF REAL DIAMONDS

The sharpening surface is coated with genuine diamond particles — one of the hardest materials available, designed to restore a precise, lasting edge with minimal effort.

THE TWO MOST COMMON ANGLES — TO FIT ANY KNIFE

This sharpener comes with two angle settings built right in:

📐 15° — ideal for thinner blades like Japanese-style or paring knives
📐 20° — ideal for thicker, Western-style kitchen knives

Whichever knife you reach for, there's an angle ready for it.

MAGNETICALLY ATTACHES TO YOUR KNIFE

No clamps. No guesswork. No holding the angle steady yourself.

The sharpener's magnetic base attaches directly to your blade, guiding it along the correct angle automatically as you roll — so even first-time users get a consistent, even edge.
