Know before you buy
No, this sharpener is specifically designed for straight-edged, double-bevel blades. Using it on serrated or single-bevel knives may damage the blade edge.
The process involves pulling your blade through three distinct slots: the first uses diamond abrasives to reshape the edge, the second refines it, and the third uses ceramic abrasives to polish the blade for a razor-sharp finish.
Yes, the design is fully ambidextrous, allowing both left- and right-handed users to operate the tool comfortably and safely.
The 16-degree angle is the optimal setting for most Kai knives, ensuring you maintain the factory-standard edge geometry for consistent, precise cutting performance.
The sharpener features a convenient retractable cover that protects the abrasive slots and allows for compact, space-saving storage in your kitchen drawer.
