The Chef’sChoice Model 15XV is a documented example of a three-stage electric knife sharpener, with diamond abrasives and angle guides. The Chef’sChoice Model 120 EdgeSelect is another documented option, using two diamond sharpening and honing stages followed by polishing and stropping. These are evidence-backed examples, not a tested ranking: the available product documentation does not establish which sharpener performs best.
What “three-stage” means
A three-stage sharpener uses a sequence of operations to shape, hone, and finish a knife edge. The exact jobs and abrasives differ by model, so the stage count alone does not tell you how a sharpener works or which knives it supports.
For example, the Chef’sChoice Model 120 EdgeSelect manual describes two precision conical diamond sharpening and honing stages, followed by a third stage for polishing and stropping. It also describes different stage sequences for producing different edge finishes. Follow the sequence and guidance for the specific sharpener rather than assuming that stages are interchangeable across models.
Two documented three-stage options
| Model | Documented design and compatibility | What the source establishes |
|---|---|---|
| Chef’sChoice Model 15XV | Three-stage electric sharpener with diamond abrasives and angle guides; stated to handle straight-edge and serrated knives. | A catalog record describes it as sharpening most 15-degree-class knives and converting 20-degree-class knives to a finer 15-degree edge. These are claims for the 15XV, not a general capability of three-stage sharpeners. See the catalog record and manufacturer product information. |
| Chef’sChoice Model 120 EdgeSelect | Two conical diamond sharpening and honing stages, then a polishing and stropping stage. | The manual says Stage 1 is generally needed less often than Stage 3 and describes Stage 3 as suitable for frequent polishing and resharpening. See the Model 120 manual. |
The available documentation supports these two examples; it does not provide a broad, current comparison of brands or independent head-to-head performance results.

How to choose a three-stage sharpener
- Identify your knives. Check whether they are straight-edge or serrated, and what edge geometry they have. Do not assume compatibility from the number of stages.
- Compare the stage design and abrasives. Confirm what each stage does and whether the manual specifies diamond abrasives, honing, polishing, or stropping.
- Match the operating method to your needs. The documented 15XV is electric. Check the product documentation for any model you are considering rather than assuming that all three-stage sharpeners operate the same way.
- Consider the kind of upkeep you need. A sharper edge needing routine touch-ups is a different use case from a dull edge needing more substantial sharpening. The Model 120 manual, for example, says Stage 1 is generally used less often than Stage 3.
- Read the model’s instructions before use. The correct stages, pressure, and supported knives are specific to the unit.
Use and care safely
For the Model 15XV, the manufacturer says, “We strongly urge that you always thoroughly clean your knives before sharpening them.” Its manual also instructs users to apply only enough downward pressure for uniform contact and never to operate the sharpener from the back side. These are instructions for that model; consult the manual for your own sharpener before sharpening.
What the available evidence does—and does not—show
The product manuals and catalog record establish design details, certain compatibility statements, and care instructions for the named models. They do not establish current prices or availability, comparative performance across the market, or a defensible ranking of the best three-stage sharpeners. Choose by matching a documented model’s design and compatibility to your knives, not by treating “three-stage” as a performance guarantee.
