Overview
The Orange Ninja is a pull-through knife sharpener from Sharp Pebble with four slots: a carbide stage for repairing damaged edges, a diamond rod stage for sharpening, a fine polishing stage, and a dedicated serrated slot, all built into one ergonomic handle.
Despite the Orange Ninja branding, the listed maker is Sharp Pebble, and here the category and title agree this is a sharpener rather than a knife or sheath. The four stage design aims to take a knife from repair through polish in one tool, more coverage than most pull-through sharpeners that only sharpen and hone.
- 4 stage system: carbide repair, diamond sharpen, fine polish, serrated slot
- Ergonomic handle usable by left or right handed cooks
- Also sharpens scissors per reviewer feedback
- ABS plastic construction
Who it's for
Works for someone maintaining a mixed set of straight and serrated kitchen knives who wants a manual, no electricity tool that also handles scissors. Not the pick for someone chasing a mirror edge on one high end knife, where a whetstone gives more control.
Pros and cons
- Works on serrated blades and scissors, not just straight edges
- Simple pull-through motion with no learning curve reported
- At least one reviewer found it did not sharpen knives well
- ABS plastic housing rather than metal construction
Performance notes
The coarse carbide slot is meant for straightening or repairing a damaged edge before sharpening, the medium slot uses diamond rods for the actual sharpening, and the fine slot polishes the edge afterward, with a separate slot cut for serrated blades. The handle is built for either hand, and the instructions call for pulling the blade through a few times per stage rather than pushing it back and forth.
