Chef'sChoice Knife Sharpener: Which Model to Buy and How Each Works

Chef'sChoice makes the most widely recommended electric knife sharpeners on the market, and their lineup spans from $25 manual sharpeners to $200 professional electric models. The right model depends on what knives you own, how sharp you want the result, and how much you're willing to spend. The 130 Professional is their most comprehensive model and works on both Western and Asian-angle knives. The Trizor XV is the choice if you want to convert German-style knives to a sharper 15-degree edge. The AngleSelect models work on both 15- and 20-degree edges in one unit.

I'll walk through each major Chef'sChoice sharpener, what it actually does to your blade, which knives it works on, and who each model makes sense for.

How Chef'sChoice Electric Sharpeners Work

All Chef'sChoice electric sharpeners use rotating diamond-coated abrasive wheels set in angled slots. You guide the blade through each slot with light forward pressure; the rotating wheels do the grinding. The angle of each slot is fixed, so you don't need to hold the blade at a specific angle manually.

Most models have 2 or 3 stages. Stage 1 uses coarser diamond abrasives to set or rebuild the primary edge. Stage 2 uses finer diamond to refine the edge. Stage 3 (on 3-stage models) uses a stropping disc or ultra-fine abrasive for the final polished finish.

The entire process typically takes 1 to 3 minutes per knife. The result is a properly beveled, sharpened edge that's consistent along the full blade length.

What About Steel Removal?

Electric sharpeners remove steel. That's how sharpening works. Chef'sChoice sharpeners are more controlled than basic pull-through carbide slots, but they do remove metal on each pass. For cheap knives you replace every few years, this doesn't matter. For high-quality knives you want to use for 20+ years, using the electric sharpener less frequently (when honing no longer restores performance) extends the blade life considerably.

Chef'sChoice 130 Professional

The 130 Professional is the standard recommendation for most home cooks with a mixed set of Western and Asian knives. It has three stages:

• Stage 1: Diamond abrasives at 20 degrees per side (coarse grind for rebuilding or dulled edges)
• Stage 2: Diamond abrasives at 20 degrees (finer grind to refine the edge)
• Stage 3: Stropping/polishing discs at 20 degrees

You use Stage 1 only when a knife is very dull or damaged. Routine sharpening uses Stages 2 and 3, which removes less steel while still restoring a good edge.

For Asian knives (15-degree edge), the 130 includes separate slots that sharpen at 15 degrees on one side (single-bevel compatible). This makes it one of the few electric sharpeners that works on both style families.

The 130 runs $150 to $180 on Amazon. It's loud when running (the motors and wheel contact are audible), and it does produce some metal dust that you want to wipe from the blade before use. It produces an edge quality that's noticeably better than pull-through sharpeners and closer to a whetstone result.

Chef'sChoice Trizor XV (Model 15)

The Trizor XV is designed for one specific use case: converting Western-style knives from a 20-degree edge to a 15-degree edge. It re-grinds the blade geometry to a sharper angle, which is a one-time process that then requires maintenance at 15 degrees going forward.

The three stages work progressively: Stage 1 grinds the new 15-degree bevel into the blade. Stage 2 refines it. Stage 3 polishes the edge to a razor finish. After conversion, you only use Stages 2 and 3 for maintenance.

The result is noticeably sharper than a standard German knife maintained at 20 degrees. If you have Wusthof, Henckels, or similar German knives and want to get closer to Japanese-level sharpness, this is how. The conversion removes meaningful steel from the first pass and repositions the entire bevel geometry, so I'd only use it on knives you intend to keep for a long time.

Price runs $150 to $160 on Amazon. The Trizor XV is a better choice than the 130 if your knife collection is predominantly German-style and you want sharper edges.

Chef'sChoice AngleSelect 1520

The AngleSelect 1520 sharpens at both 15 and 20 degrees using the same machine. You choose the slot corresponding to your knife's edge angle. Three stages are included (two diamond, one stropping). This makes it the most versatile single model if you have a mixed collection of German and Japanese knives.

It runs $130 to $150 and is the one model I'd recommend if you have both European and Asian knives in your kitchen.

Chef'sChoice Manual and Budget Models

Chef'sChoice Manual Sharpener 4633

A two-stage manual pull-through with diamond abrasive wheels (not fixed carbide slots). It's more controlled than standard carbide pull-throughs because the diamond wheels rotate as the blade passes through, similar to the electric models but powered by your hand motion. One stage at 15 degrees, one at 20 degrees.

This runs $25 to $35 and is a solid budget option that bridges the gap between cheap pull-throughs and full electric models. No motor noise, no electricity needed. Good for occasional use where an electric sharpener is overkill.

Chef'sChoice 4643 Asian Knife Sharpener

A dedicated two-stage electric sharpener at 15 degrees for Asian-style knives. If your kitchen is exclusively Japanese knives (Shun, Global, MAC, etc.) and you want a simple, focused electric sharpener, this is worth considering at $50 to $60.

Chef'sChoice vs. Other Electric Sharpeners

The main competitors are Presto, Work Sharp, and KitchenIQ electric models. At the $30 to $60 price range, Presto's models work reasonably well for budget knives. For quality knives in the $100+ range, Chef'sChoice's precision edge angle control and better abrasive materials justify the higher price.

Work Sharp electric sharpeners use belts rather than wheels and are more popular with outdoor and hunting knife maintenance. For kitchen knives specifically, Chef'sChoice's wheel-based system is better suited to the blade geometry.

Sharpening Japanese Knives with Chef'sChoice

Some high-hardness Japanese knives (61+ HRC) require extra care in electric sharpeners. The harder steel can behave unexpectedly under aggressive diamond abrasion. For premium Japanese knives like Shun Premier or MAC MTH-80, the 130 Professional's Asian slots or the AngleSelect 1520 set to 15 degrees work, but use only Stages 2 and 3 rather than starting with Stage 1 unless the knife is truly very dull. Most Japanese knife enthusiasts prefer whetstones for these knives because whetstone sharpening gives you more feedback and control.

How Often to Use Your Chef'sChoice Sharpener

The most common mistake is over-sharpening. You don't need to run a knife through a sharpener every week. The correct workflow:

1. Before each use: hone with a ceramic or smooth steel rod (2 minutes, doesn't remove steel)
2. When honing stops restoring performance: sharpen with your Chef'sChoice (Stages 2 and 3 only for regular maintenance)
3. When the edge has visible damage or is completely flat: use Stage 1 to rebuild, then 2 and 3

For a home cook using knives 4 to 5 times per week with regular honing, electric sharpening 2 to 4 times per year is typically sufficient.

FAQ

What's the best Chef'sChoice model for German knives?

The Trizor XV converts German knives to a sharper 15-degree edge, which is the best performance upgrade you can make to a Wusthof or Henckels. The 130 Professional maintains German knives at 20 degrees, which is more appropriate if you want to preserve the original edge geometry.

Can Chef'sChoice sharpeners damage my knives?

They remove steel, which is necessary for sharpening. Using Stage 1 when only Stages 2 and 3 are needed removes steel unnecessarily. Following the correct stage for the knife's condition minimizes unnecessary steel removal.

Is Chef'sChoice better than a whetstone?

A whetstone gives you more control and can produce a sharper result in skilled hands. Chef'sChoice is faster, requires no technique, and produces excellent results consistently. For most home cooks, the Chef'sChoice is a better practical choice. For knife enthusiasts who enjoy the sharpening process, a whetstone is more satisfying.

Do Chef'sChoice sharpeners work on serrated knives?

No. Serrated knives require a specialized serrated sharpener or professional sharpening. Running a serrated knife through a Chef'sChoice electric sharpener grinds the serrations flat.

The Right Model for Your Kitchen

If you have German-style knives and want the best performance upgrade: Trizor XV. If you have a mix of German and Japanese knives and want one machine for both: AngleSelect 1520. If you want the full-featured model that works on nearly everything including Asian single-bevel knives: 130 Professional. If you want a quality manual sharpener without the motor: the 4633 manual model at $30. Start with the right model for your knife collection and the sharpening process becomes a 3-minute task rather than a skill you need to learn.
