Presto Eversharp Electric Knife Sharpener: Complete Review

The Presto Eversharp is one of the most recognizable entry-level electric knife sharpeners on the market. It's been available for decades, has sold millions of units, and shows up in a large percentage of home kitchens that own any electric sharpener at all. If you're evaluating whether the Eversharp is the right tool for your knives, this guide gives you the full picture.

What Is the Presto Eversharp?

The Presto Eversharp (model 08800) is a two-stage electric knife sharpener made by National Presto Industries, an American appliance company based in Wisconsin. It's designed for quick, simple knife sharpening with no manual sharpening skill required, you pull the knife through, and the sharpener does the work.

The model has been in continuous production through multiple versions. The 08800 is the most widely available and the one most home cooks mean when they refer to "the Presto Eversharp."

How the Presto Eversharp Works

The Eversharp uses two stages:

Stage 1 (Sharpening): A set of rotating sapphire-impregnated sharpening wheels grinds the blade edge to restore sharpness. The wheels are angled at approximately 20 degrees per side, matching standard Western knife geometry.

Stage 2 (Stropping/Finishing): A set of rotating strop wheels (soft material) polishes and finishes the edge after grinding, removing the wire edge (burr) left by the first stage and refining the edge texture.

The process takes 5-10 seconds per knife. Pull the blade through stage 1 two to three times with light pressure, then pull through stage 2 two to three times. Done.

Performance Assessment

What It Does Well

Speed: Few sharpening methods are faster. A dull kitchen knife can be restored to working sharpness in under a minute with no setup or technique learning curve.

Accessibility: There's essentially no skill required. The fixed-angle guides mean you can't mess up the edge geometry with poor angle control, which is the most common mistake when using manual whetstones.

Consistency: Because the angle is fixed, the results are consistent between sessions. You won't accidentally change the edge angle over time.

Suitability for the target user: The Eversharp was designed for home cooks who don't think much about knife maintenance. For that user, it delivers a functional sharp edge reliably.

Limitations and Trade-offs

Metal removal: Electric pull-through sharpeners remove more metal per sharpening session than whetstones because the abrasive wheels work aggressively. Over time, with frequent use, this shortens blade life compared to whetstone maintenance.

Edge quality: The edge produced by the Eversharp is functional but not as refined as a whetstone edge. The rotating wheels create a slightly rough apex compared to the clean, polished edge possible on quality whetstones. For practical home cooking, this difference is minor; for knife enthusiasts, it matters.

20-degree angle only: The fixed 20-degree angle is correct for Western-style (German) knives but too wide for Japanese knives (typically 15 degrees per side). Running a Japanese knife through the Eversharp changes its edge geometry, not catastrophic, but not optimal either.

Serrated knives: The Eversharp cannot sharpen serrated blades. A separate serrated knife sharpener or professional sharpening is needed for those.

Single-bevel Japanese knives: Not compatible. Single-bevel knives require specialized sharpening on waterstones.

Who the Presto Eversharp Is Right For

Works well for: - Home cooks with German-style knives (Wusthof, J.A. Henckels, Victorinox Fibrox, etc.) who want the simplest possible sharpening routine - Households where knives get minimal maintenance and need restoration quickly - Anyone who finds whetstones intimidating or doesn't want to learn the technique - Time-constrained cooks who want a functional edge in 30 seconds - Secondary kitchens, rental properties, or anywhere that needs basic maintenance without precision

Not right for: - Japanese knife owners (15-degree edge geometry not matched by Eversharp's 20-degree) - Collectors or enthusiasts who want the best possible edge quality - Anyone who cooks at a high level and wants maximum performance from their blades - Owners of high-end knives where steel preservation matters

Presto Eversharp vs. Alternatives

vs. Chef'sChoice 4643 (Manual)

The Chef'sChoice 4643 is a manual pull-through sharpener in a comparable price range. It offers three stages and slightly more control than the Eversharp. Edge quality is similar; the Chef'sChoice is slightly slower but more thorough. Personal preference in manual vs. Electric operation is the main differentiator.

vs. Chef'sChoice Model 130 (Electric)

The Chef'sChoice 130 is a more advanced electric sharpener with three stages and angle flexibility. It produces a better edge than the Eversharp and handles Asian-geometry knives. It's also more expensive, roughly 2-3x the price. If you own quality Japanese knives, the Chef'sChoice 130 (or the specific angle-adjustable Asian models) is worth the step up.

vs. Whetstone Sharpening

Whetstones produce the best edge quality and remove the least metal over time. They require learning technique, maintaining a consistent angle during sharpening takes practice. For a home cook willing to spend 20-30 minutes learning the basics, a good whetstone setup produces far better results than any pull-through sharpener. For a home cook who won't invest that learning time, the Eversharp is more practical.

vs. Honing Rod

A honing rod is not a sharpener, it's a realignment tool that straightens the edge between sharpenings without removing metal. Regular honing extends the time between sharpening sessions dramatically. Ideally, use a honing rod before each cooking session and the Eversharp (or whetstone) a few times per year when honing no longer restores performance.

Using the Presto Eversharp Effectively

Light pressure: The sharpener does the work. Forcing the blade through with excess pressure doesn't improve results and increases metal removal.

Stage 1 first, stage 2 always: Never skip stage 2, the strop stage removes the burr left by the grinding stage and is necessary for a functional edge. Knives feel scratchy without stage 2 finishing.

Count strokes: 2-3 pulls per stage is typically sufficient. More pulls remove more metal without proportionally improving the edge.

Clean the blade after: Some steel filings transfer to the blade during sharpening. Wipe the blade clean before cooking.

Don't over-sharpen: Use stage 1 only when the knife is genuinely dull. For maintenance between full sharpenings, a few pulls through stage 2 only (the strop) can refresh a slightly dull edge.

FAQ

Can the Presto Eversharp sharpen Japanese knives? It can, but at the wrong angle (20 degrees vs. 15 degrees standard for Japanese knives). Running Japanese knives through the Eversharp changes their edge geometry. For Japanese blades, use a whetstone or a sharpener with adjustable angle settings.

How long does the Presto Eversharp last? The sharpening wheels are consumable, they lose effectiveness over years of use. Many buyers report the unit working well for 5-10 years of regular home use before the wheels noticeably degrade.

Can you sharpen scissors in the Presto Eversharp? No. The Eversharp is designed only for straight-edge kitchen knives. Scissors require a different sharpening geometry.

Does the Presto Eversharp work on serrated knives? No. Pull-through electric sharpeners cannot handle serrated edges. Serrated knives require a dedicated serrated knife sharpener (with a thin conical rod) or professional sharpening.

Is the Presto Eversharp worth the price? For German-style knife owners who want the simplest maintenance approach possible, yes. For precision-oriented cooks or Japanese knife owners, better-suited alternatives exist.

How often should you use the Presto Eversharp? Use stage 1 (sharpening) only when the knife is genuinely dull and honing no longer works. Overuse of the grinding stage removes more steel than necessary. A few times per year for regular home cooks is typical.
