Presto 08810 Professional EverSharp Electric Knife Sharpener

Presto EverSharp Electric Knife Sharpener Review

Presto has been selling the same electric knife sharpener design since the 1990s under model numbers 08800 and 08810, and the reason it is still on shelves is that it correctly identified what home cooks actually need — a two-stage grind at a fixed 25-degree Western angle that takes a dull chef’s knife to functional in about 45 seconds. It sits at $69.29 on sale from $89.99, has 10,833 reviews at 4.5 stars, and is the answer to a question that most kitchen guides overthink.

The competition here is Chef’sChoice at $170 and the Amazon-native $40 tier that dominates search results. Presto is deliberately in the middle: a real US brand with a decades-long track record, sapphirite (aluminium oxide) wheels rather than diamond, and a spring-loaded blade guide that keeps the knife at the right angle without requiring skill. The whole appliance is 60 seconds of practical value performed reliably for a decade.

Quick verdict: the Presto EverSharp knife sharpener scores 8.3/10 in this SoftPickr review. a fixed 25-degree Western sharpener with sapphirite wheels and a real spring guide is exactly what most home cooks need.

Key Specifications

Two Stages and the 25-Degree Angle Choice

Presto’s design philosophy is simplicity. Stage 1 is a coarse-grit sapphirite wheel that grinds a new bevel; Stage 2 is a fine-grit sapphirite wheel that polishes the same bevel to a working edge. Both stages hold the knife at exactly 25 degrees per side by a pair of spring-loaded plastic guides. The result is a repeatable 50-degree inclusive Western angle that matches Wusthof, Henckels, Global and the vast majority of American kitchen knives.

The 25-degree choice is not adjustable, and that is a deliberate constraint. Buyers with a Japanese single-bevel yanagiba or a 15-degree Shun should not put those knives near this machine. Everyone with a straight-edge Western knife — the honest description of at least 90 percent of American home kitchens — gets a factory-consistent edge in 45 seconds without having to know what a burr is.

Sapphirite Wheels vs Diamond

Aluminium oxide, marketed by Presto as sapphirite, is a slightly softer abrasive than the diamond wheels premium sharpeners like Chef’sChoice use. In practice this means Presto removes less metal per pass, which is exactly what a home cook wants: an over-aggressive diamond wheel takes a chef’s knife from full width to a paring knife over five years of use. The Presto extends the useful life of the same knife by a decade.

The trade-off is speed on a truly ruined edge. A knife that has been abused into a curved profile — for example, one used repeatedly on a glass cutting board — needs three or four passes through Stage 1 to rebuild the geometry. A diamond wheel does the same job in one pass. For a mainline chef’s knife touched up every three weeks the sapphirite is the better wheel; for a rescue job on a nine-year-old ignored blade the diamond is faster.

Spring-Loaded Blade Guides and the Skill Question

The most useful feature Presto ships is the pair of spring-loaded plastic guides on each side of each slot. They apply light lateral pressure to the blade as it draws through, which forces the edge to sit at exactly 25 degrees against the wheel regardless of how the user is holding the handle. This is why a first-time user gets a factory edge on their first try; the machine simply does not allow a wrong angle.

The practical result is that anyone in the household can sharpen the kitchen knives safely. A whetstone requires learning to feel the burr and to maintain a consistent bevel angle across a stroke; that is a real hobby and it produces a superior edge. The Presto trades that top-end quality for the reliable middle: a professional-adjacent edge with zero learning curve, delivered by an unskilled user in under a minute.

Serrated Edges, Scissors and What Not to Put in the Slot

Stage 2 accepts serrated bread knives and delivers a mild polish on the flat side of each serration, which restores tomato-slicing performance on a bread knife dulled to slipping. Do not put serrated blades in Stage 1; the coarse wheel will destroy the serration geometry within three passes. Poultry shears, kitchen scissors and thin-bladed paring knives all work in both stages provided the blade is a straight-edge Western pattern.

The two categories to keep away entirely are ceramic knives (which chip on the wheel and will damage the sapphirite) and Japanese single-bevel knives whose entire performance depends on a 15-degree angle the Presto cannot produce. Also avoid box cutters and utility knives with disposable segmented blades; the segmented steel is too soft and gums the wheel with metal transfer that requires a full clean.

Limitations and Compromises

The 25-degree angle is fixed and not user-adjustable. Buyers migrating to a Japanese Shun or a Miyabi should not use this sharpener because it will grind a Western bevel on a Japanese knife within one pass and permanently change the knife’s cutting geometry. Anyone with a mixed Western-and-Japanese knife block needs a separate sharpener for the Japanese blades, most affordably an inexpensive whetstone at 3000 grit.

Sapphirite wheels wear over time. Presto’s stated life is roughly ten years of typical home use, meaning about one sharpening session per week; heavier users may see wheel wear at year 7 or 8 in the form of a duller edge coming out of Stage 2. Replacement wheels are not user-serviceable; the machine itself is the replacement, which the $69 price point makes acceptable but is worth understanding.

The magnetic metal-shavings tray needs emptying every twenty or so sharpening sessions or the accumulated ferrous dust bridges the wheel gap. Presto’s user manual mentions this in a single line that is easily missed; a neglected tray causes a Stage 2 grind that leaves visible black streaks on the polished side of the knife, which is metal dust rather than damage but is the failure mode that generates the majority of one-star reviews.

Cleaning and Long-Term Care

The magnetic metal-shavings tray sits under both wheels and lifts out with a single pull. Empty it into the trash after every twenty or so sharpenings; ferrous dust accumulation is the single most common cause of poor performance on an otherwise healthy machine. A dry brush removes remaining dust from the tray recess. Never wash the tray or the machine housing under running water because the motor and wheel bearings will corrode.

The wheels themselves are self-cleaning during normal use; each pass of a knife slightly dresses the wheel. If the wheels ever show a black glaze from soft-steel knife metal transfer, run a Stage 1 pass with a hard high-carbon knife (a paring knife works well) to break the glaze off. Store the sharpener with the cord loosely wrapped around the base and the tray reinserted to keep dust out of the wheel slots.

Who Should Buy It?

• A mainstream household with a Wusthof, Henckels, Global or Cuisinart knife block that has never been sharpened
• A cook whose knife maintenance is currently the honing steel in the drawer and no actual sharpening
• A busy household where the sharpener will be used by whoever is cooking, not only the most careful adult
• A gift for someone who inherited a set of good knives and would benefit from a $70 tool rather than a $170 one
• Anyone who has already tried a whetstone and does not want to keep up the practice required to use it well

Buyers with a Japanese single-bevel or 15-degree knife need a separate 15-degree sharpener like the Chef’sChoice 316; a professional or serious hobbyist should invest a weekend of practice in a proper whetstone and freehand technique; owners of only two dull knives who sharpen twice a year should skip this and use a $15 pull-through carbide sharpener.

SoftPickr Verdict

The Presto EverSharp knife sharpener earns 8.3/10. Presto has left this design essentially unchanged for a quarter century because it does the job the mainstream American kitchen actually needs. Two stages of sapphirite wheels, a fixed 25-degree Western angle enforced by spring guides, and a low-speed AC motor that never overheats a blade. It is not aspirational, it does not connect to an app, and it will still be sharpening the same knives after a decade of weekly use.

The honest compromise is that it is a Western sharpener only, and it takes wheel-wear over ten years rather than being rebuilt. Buyers who own Japanese knives or who want the last five percent of edge quality should look elsewhere. Everyone in the mainstream middle is getting exactly the right tool for the job, sold by an American appliance brand with a 4.5-star rating across 10,833 owner reviews.

Presto EverSharp knife sharpener — Frequently Asked Questions

What angle does the Presto EverSharp knife sharpener use?

The EverSharp holds knives at exactly 25 degrees per side (50 degrees inclusive) using spring-loaded plastic guides on both sides of each slot. This is the standard Western angle that matches Wusthof, Henckels, Global, Cuisinart and virtually every American kitchen knife brand. The angle is fixed and not user-adjustable.

Can I sharpen Japanese knives on the Presto EverSharp?

No. Japanese knives use a 15 to 17 degree angle per side (versus this sharpener’s 25 degrees) and putting a Shun or a Miyabi in the slot will grind a Western bevel on a Japanese knife within one pass and permanently alter its cutting geometry. Buyers with Japanese blades need a separate 15-degree sharpener.

Can I sharpen serrated knives on the Presto EverSharp?

Yes, but only in Stage 2 (the fine wheel). Stage 2 delivers a mild polish on the flat side of each serration and restores tomato-slicing performance on a bread knife. Never run a serrated blade through Stage 1, because the coarse wheel destroys the serration geometry in three passes.

How long do the Presto EverSharp wheels last?

Presto rates the sapphirite wheels for roughly ten years of typical home use — about one sharpening session per week for the household’s main knives. Heavier users may see wheel wear at year 7 or 8. Replacement wheels are not user-serviceable; the machine itself is the replacement at the $70 price point.
