Consistent, precise sharpening angle
The set comes with a magnetic holding block and preset 15° and 20° angle guides, which help ensure the knife is sharpened at the correct and consistent angle — whether it’s a Japanese-style knife or a Western-style knife.
That consistency avoids uneven sharpening from heel to tip — a common problem with freehand whetstones or pull-through sharpeners.
Fast and easy sharpening — minimal skill required
The rolling mechanism significantly speeds up sharpening: the manufacturer claims it is “5× quicker than any other sharpening method.
Because of the guided and automated nature, even users with little or no sharpening experience can get reliably sharp knives — reducing the need for mastering angle, pressure, and stroke control.
Durable, quality construction & long-lasting abrasives
The use of diamond abrasive discs (coarse + fine) means the sharpening surface is hard — so the discs should hold up well over time and deliver effective cutting-edge restoration without frequent replacement.
Convenience, low-maintenance & versatile for everyday kitchen use
Because it’s compact and manual (no electricity or bulky setup), it’s easy to store and quick to use — ideal for home kitchens where users want sharp knives without the mess or effort of whetstones.
