How It Works
Sharpen Asian style knives and contemporary Euro/American style knives at the traditional 15 degree angle, using Stage One and then Stage Three. Sharpen traditional European/Western style knives at a 20 degree angle, using Stage Two, followed by Stage Three. The initial stages sharpen and hone using 100% diamond abrasives while the third stage polishes the edge with micron sized diamond abrasives. Stage Three is also used to sharpen serrated knives. The result is a symmetrical, arch-shaped knife-edge that is sharper and resists dulling longer.
The Pronto incorporates Chef’sChoice signature diamond abrasives. Diamonds are preferred for their superior characteristics over other sharpening materials. Diamond abrasive wheels will hold their shape indefinitely (unlike ceramic wheels which lose shape over time) and can sharpen any alloy. Diamonds are also the most durable abrasive and will last and last. Chef’sChoice diamond abrasives will not load up and there is no messy water or oils needed for sharpening.
