Know before you buy
Yes. The ProntoPro features dedicated slots for both 15-degree Asian-style blades and 20-degree European or American-style blades, making it versatile enough for a mixed knife collection.
Yes, it is designed to sharpen serrated edges. The diamond abrasives effectively hone the teeth of the blade to restore their cutting performance.
The Criss-Cross technology uses diamond abrasives to sharpen both sides of the blade simultaneously. This creates a sharper, burr-free edge much faster than traditional manual sharpeners.
Not at all. The ergonomic handle and the design of the sharpening stages are fully symmetrical, making it comfortable and safe for both left- and right-handed users.
No, the sharpener includes integrated angle guides that hold the knife at the correct angle throughout the entire stroke. This ensures a consistent edge from the tip of the blade all the way to the bolster.
Stages 1 and 2 are used for sharpening and honing the edge, while Stage 3 is designed for polishing and finishing. For regular maintenance, you may only need to use the polishing stage, but use all three if your knife has become noticeably dull.
