Overview
Chef'sChoice builds the Pronto 464 as a handheld two-stage sharpener that pulls the blade through diamond abrasive wheels. The first stage sharpens, and the second stage hones and polishes the edge to an arch-shaped finish.
Everything about the Pronto is aimed at quick, repeatable sharpening: a fixed guide sets the angle, so no skill with a stone is needed. Micron-size grit in the finishing step leaves a polished edge. The fixed angle is the compromise.
Who it's for
People who sharpen a drawer of mixed straight and serrated knives will get the most from the fixed guide and the diamond wheels. Enthusiasts who choose their own angles, or who prefer whetstones, will find the preset angle limiting.
Pros and cons
- Two stages in one compact body
- Diamond abrasives on any alloy
- Handles straight and serrated edges
- Preset bevel angle needs no setup
- Single fixed edge angle
- Cleaning instructions not listed
- Manual pulling takes some effort
Performance notes
Diamond abrasive removes metal on any alloy, and the angle guide presents the blade to the wheel at the same bevel each pass. Stage one sets the edge and stage two refines it with micron-size diamond, which is why the finish reads as polished instead of coarse.
