A manual sharpener with two diamond stages, one for sharpening and one for honing, set at 15 degrees. Chef’sChoice aims it at santokus and other 15-degree knives.
The claim to ignore
“The fastest manual Santoku and 15 degree style knife sharpener available” has nothing behind it in the listing.
Where it sits
Its bigger sibling, the 15 and 20 degree model, costs about $22 more and works on Western knives. For very little money, the Smart Sharp and the Work Sharp also do the basic job.

The questions that come in
Can I use the Pronto on my Wüsthof?
It would reshape the edge toward 15 degrees. Many modern German knives have moved to narrower angles, so check your knife’s stated angle before choosing.
Does it work on a serrated knife?
The title says straight-edge and serrated, which helps keep a bread knife going.
