The Work Sharp E2 is worth buying if you want consistent, low-effort sharpening for ordinary double-bevel kitchen knives and you are happy with a fixed angle. It is a poor fit for single-bevel Japanese blades, ceramic knives, and anyone who needs variable angles. The E2 holds the blade at a fixed 20-degree angle and uses flexible abrasive discs rather than rigid stones. Work Sharp describes it as its first sharpener to use flexible abrasive discs instead of belts, and its first to include a guided ceramic pull-through slot for honing.
How the Work Sharp E2 Sharpens Kitchen Knives
The E2 uses flexible P120 ceramic abrasive discs to restore a dull edge, paired with a fine-grit ceramic honing wheel for upkeep between full sharpenings. Because the abrasive is flexible, it conforms slightly to the blade rather than flat-grinding the geometry away. The machine runs at a single sharpening speed and shuts off automatically when the cycle finishes.
The fixed 20-degree guide is the central fact to weigh before buying. If your knives already sit near that angle, the E2 removes relatively little metal to maintain them. If your knives were ground at a noticeably different angle, expect the first sessions to reprofile the edge and remove more material.
Proper Technique for Using the E2
The machine controls the angle, so your job is controlling the draw. Pull the knife through the guide at roughly one inch per second, and alternate sides with each pass. Consistent, light pressure works better than forcing the blade into the slot.
Handle the tip deliberately. As the curved portion of the blade reaches the guide, lift the handle slightly so the tip keeps contact with the abrasive. Skipping this step is the usual cause of rounded tips.
Which Knives Are Compatible and Which Are Not
| Knife Type | Suitability |
|---|---|
| Standard double-bevel kitchen knives | Intended use; fixed 20-degree guide |
| Serrated bread knives | Retailer claims refresh capability; verify against your manual |
| Single-bevel Japanese knives | Not suitable; the fixed double-bevel angle will alter the geometry |
| Ceramic knives | Do not use; hard, brittle blades risk shattering |
The E2 also includes a scissor sharpening guide, which adds some versatility beyond knives. For serrated blades, treat retailer claims of refresh capability as limited: the same retailer describes it as extending sharpness on bread knives, not restoring worn serrations. The safe default is to keep serrated and single-bevel knives away from the powered discs unless your own manual explicitly says otherwise.
Safety note: never run a ceramic knife through the E2. Ceramic is brittle, the abrasive will not sharpen it, and a shattered blade is a laceration risk.
Comparing the E2 to Manual Stones and Carbide Sharpeners
| Feature | Work Sharp E2 | Manual Whetstone | Carbide Pull-Through |
|---|---|---|---|
| Skill required | Low; angle is guided | High; freehand angle control | Very low |
| Consistency | High, machine-guided | Depends on user | High but crude |
| Edge character | Discs plus ceramic honing | User-controlled | Can leave a toothy edge that dulls quickly |
| Adjustable angle | No; fixed 20 degrees | Yes | No |
| Best for | Everyday double-bevel knives | Buyers who want control | Fast, cheap touch-ups |
Manual stones give you angle and grit choices the E2 cannot, which matters for specialized cutlery. They also demand practice; freehand sharpening produces inconsistent results until you build the skill. Carbide pull-throughs are quick and simple, and independent testing notes that pull-through results can be less sharp than a whetstone finish, though the method is fast and easy. Carbide cutters in particular are associated with aggressive metal removal and a toothy edge that dulls quickly.
Powered disc systems are not automatically gentler than other methods. Belt and disc sharpeners can remove metal quickly and change blade geometry when used heavily. The E2’s fixed guide supports consistency; it does not make heavy-handed use harmless.
Cost, Warranty and What You Are Actually Paying For
Prices move, so check current listings before buying. One specialist retailer listed the E2 at $59.95 against a $79.95 original price, and replacement abrasive discs at $9.95 against $11.95. Work Sharp’s 2018 launch announcement put the starting price at $49.95, with an optional scissors and pocket-knife upgrade for $30 more; treat that figure as historical. Work Sharp’s current site lists a “Kitchen Electric Knife Sharpener” at $87.95 without naming the E2 in that listing, so confirm the exact model and price at checkout.
The E2 carries a three-year warranty, consistent with Work Sharp’s statement that every sharpening machine it sells comes with a three-year warranty. Warranty terms beyond the duration, including exclusions and the claim process, were not available for this article.
Work Sharp states its abrasives are formulated, designed and made in America by Norton. That speaks to abrasive sourcing, not to measured edge performance.
Assessing Your Knife Collection Before Buying
The E2 is built for the workhorse knives in a home kitchen: chef’s knives, paring knives, slicers, carvers and utility knives with standard double-bevel edges. Before buying, sort your collection into three groups:
- Everyday stainless double-bevel knives: the E2’s core use case at its fixed angle.
- Serrated blades: limited support at best; the retailer’s claim covers refreshing, not full serration restoration.
- Single-bevel, ceramic and high-end specialty blades: keep these off the E2 and use a method matched to their geometry.
If most of your knives fall in the first group, the E2 fits your kitchen. If the second and third groups dominate, a manual system gives you the control those blades need.
Troubleshooting Common Sharpening Errors
Most problems with a guided sharpener come from technique, not the machine.
- Rounded tips: lift the handle as the blade curve reaches the guide so the tip stays in contact.
- Uneven edges: count passes and alternate sides evenly; the recommended rhythm is alternating sides with each pass.
- A sharp knife that still snags: a burr or wire edge is likely. A few light passes on the fine ceramic honing stage usually clears it.
- No improvement after many passes: the abrasive may be worn, or your draw speed may be off; the target is about one inch per second.
Maintenance and Replacement Discs
Sharpening produces metal swarf, and it collects inside the unit. Clear it periodically so dust does not interfere with disc rotation or the motor. The compact footprint and cord storage in the base make the E2 easy to keep on hand, which also makes regular cleaning easier to remember.
Replacement discs are the main consumable. One specialist retailer listed them at $9.95. A specific replacement interval for the E2 was not available; judge wear by results. When a knife that used to sharpen in a handful of passes needs many more, the abrasive is likely spent. Keep a spare set on hand so maintenance does not stall.
Final Purchase Decision
Buy the Work Sharp E2 if you sharpen standard double-bevel kitchen knives, want a guided 20-degree edge without learning freehand technique, and accept roughly $60 or more upfront plus about $10 for replacement discs. Skip it if you own single-bevel Japanese knives, ceramic blades, or cutlery ground at angles you need to preserve; a manual stone, or professional sharpening, serves those better. The three-year warranty backs the purchase for normal home use. Confirm the exact model and current price before checkout, since listings vary.
