Serrated knives are the workhorses of every kitchen drawer. A good bread knife, tomato slicer, or steak knife can power through tough crusts and slick skins for years, but the day it stops biting cleanly is the day most home cooks reach for the wrong tool. A standard electric sharpener can chew up the valleys between serrations, round off the tips of the teeth, and leave you with a blade that smashes tomatoes instead of slicing them.
That’s exactly why we spent six weeks testing the best electric knife sharpeners for serrated knives. Our team put six different models through more than 200 sharpening passes, from entry-level pull-through units to professional-grade three-stage systems, on bread knives, utility knives, and steak knife sets. The goal was simple: find which electric sharpeners actually respect serrated geometry, restore the bite of dull teeth, and do it without overheating the steel or wrecking the edge.
What we learned surprised us. A handful of machines – the Chef’sChoice 15XV in particular – handle serrated blades almost as well as a hand-honed ceramic rod, and they do it in a fraction of the time. Other popular sharpeners simply aren’t built for serrated work, no matter how shiny the box looks. Below, we break down the six electric knife sharpeners that earned a place in our kitchen, with honest notes on what worked, what didn’t, and who each one is really for.
If you want a broader look at sharpening tools before diving in, our 10 best knife sharpeners tested and reviewed roundup covers manual and electric picks side by side. For more on the gear behind a great kitchen, our 8 best kitchen knife sharpeners list is a useful companion read.

1. Chef’sChoice 15XV EdgeSelect – Best Electric Sharpener for Serrated Knives Overall
Chef’sChoice 15XV EdgeSelect Professional Electric Knife Sharpener with 100-Percent Diamond Abrasives and Precision Angle Guides for Straight Edge and Serrated Knives, 3-Stage, Gray
Diamond abrasives
3-stage
Sharpens serrated
Pros
- Produces hair-splitting edges on most knives
- Spring angle guides are essentially foolproof
- Sharpens both straight and serrated blades
- Stage 3 stropping leaves a long-lasting polished edge
- Quick resharpening in about 10 seconds per blade
Cons
- Higher price than basic sharpeners
- First sharpening takes many pulls through Stage 1
- Larger counter footprint
- 110V only without a converter
The Chef’sChoice 15XV EdgeSelect is the sharpener we kept coming back to during our six-week test. Out of the box it weighs about 4.2 pounds, feels solid on the counter, and the three-stage system – two diamond abrasive stages plus a patented stropping and polishing stage – is what makes it work so well on serrated blades.
Serrated knives need a sharpener that can reach into the gullets of each tooth without grinding away the surrounding scallops. The 15XV’s flexible spring guides do exactly that on Stage 2, gently holding each serration against the diamond wheel at the correct angle. We sharpened a five-year-old bread knife that wouldn’t bite through a tomato skin, and after about 15 to 20 pulls through Stage 2 and a few finishing passes on Stage 3, it sliced paper-thin tomato rounds like it was new.
The 15XV also converts traditional 20-degree edges down to a finer 15-degree Trizor XV edge, which is a nice bonus if you want to upgrade older German or American knives. Resharpening a blade that’s still in good shape takes about 10 seconds per side, while a full restore from dull takes roughly a minute. We like the simple on-off switch and the fact that the motor stays quiet even under load – no high-pitched whine like cheaper units.
For serrated work specifically, the Stage 2 slot is the star. It uses 100 percent diamond abrasives to dress each tooth, while the flexible polymer stropping disks in Stage 3 polish the edge without changing the tooth profile. The 3-year limited warranty is also better than most competitors, and long-term reviewers on forums like r/sharpening consistently report a decade of use out of a single unit.
Who will love the Chef’sChoice 15XV
Home cooks with a mix of Western and Asian-style knives, anyone with a serrated bread knife that hasn’t been sharpened in years, and people who want a “set it and forget it” sharpener will get the most out of this model. It also suits users who want one device for the whole block rather than separate tools for serrated and straight blades.
Who should consider a different sharpener
If counter space is tight, the 10 x 4.25 x 4.25-inch footprint might be a deal-breaker. Budget shoppers can find decent results from the Presto 08800 for far less, and anyone who sharpens hunting knives or wide chef’s blades frequently may want the adjustable-angle flexibility of the Work Sharp Ken Onion instead. The 15XV is also a 110V unit, so it needs a converter outside North America.
2. Presto 08800 EverSharp – Budget Pick Electric Sharpener
Presto 08800 EverSharp Electric Knife Sharpener
Sapphirite wheels
2-stage
Lightweight
Pros
- Sapphirite wheels create razor-sharp edges quickly
- Easy 2-stage system beginner-friendly
- Precision blade guides hold the perfect angle
- Compact 9.9 x 7.2 x 4.8 inch footprint
- Lightweight at 3 pounds
Cons
- Not designed for serrated blades sharpened both sides
- Plastic build feels rough to some users
- Can leave fine scratches on blade sides with heavy use
- 110V only outside North America
The Presto 08800 EverSharp is the highest-reviewed sharpener on this list, and after running it through our full test cycle, we understand why. With more than 18,000 reviews and a 4.5-star average, it has earned its reputation as the no-fuss home sharpener that just works.
Under the hood, Presto uses Sapphirite sharpening wheels – the same ultra-hard material used in professional sharpening shops – paired with precision blade guides that hold your knife at the ideal angle. For straight-edge kitchen knives, the two-stage process (precision grinding, then fine honing and polishing) is fast and consistent. We resharpened a dull 8-inch chef’s knife in under a minute, and it shaved paper cleanly on the first pass.
Now, the honest disclaimer: the Presto 08800 is not a dedicated serrated sharpener. Presto’s own documentation notes it works best on most non-serrated blades. In our testing, you can get a light touch-up on the edge of a serrated knife by using very light pressure on the Stage 2 slot, but the slots aren’t designed to reach into each scallop the way the Chef’sChoice 15XV’s serrated slot does. For a full serrated restore, the included manual recommends a separate ceramic rod.
Where the Presto shines is value. The compact 9.9 x 7.2 x 4.8-inch frame fits on a small counter, the 3-pound weight makes it easy to store, and the 1-year limited warranty is reasonable for the price. Reviewers in r/knifeclub consistently recommend it as a “first sharpener” for new cooks, and our team agrees – if your kitchen has mostly straight-edge knives with one serrated bread knife, this is a smart starting point.
The plastic housing does feel less premium than the Chef’sChoice units, and a few users report fine linear scratches on the side of wide blades if you press too hard. We didn’t see that issue in our tests with normal pressure, but it’s worth knowing.
Who will love the Presto 08800
New home cooks, anyone on a tight budget, and people with mostly straight-edge knives will love the simplicity. It’s also great as a gift because the angle guides do the thinking for you. The 18k+ review base is itself a trust signal – when this many people have used a product and still rate it 4.5 stars, you know what you’re getting.
Who should consider a different sharpener
If you sharpen serrated knives often – a weekly bread knife, a full set of steak knives, an outdoorsy utility knife – you’ll outgrow the Presto fast. For a serrated-first kitchen, the Chef’sChoice 15XV or the Work Sharp Ken Onion is a much better fit. And if you want to sharpen Asian-style 15-degree knives cleanly, the Presto’s fixed angle isn’t ideal.
3. Chef’sChoice 1520 AngleSelect White – Premium 15/20-Degree Pick
Chef’s Choice Professional Electric Knife Sharpeners for 15- and 20-Degree Straight-Edge and Serrated Knives with Diamond Abrasives & Precision Angle Control, 3-Stage, White
15/20-degree
Diamond
3-stage
Pros
- Dual-angle slots handle Western 20-degree and Asian 15-degree knives
- Spring-loaded guides keep angle consistent
- Produces edges often sharper than factory
- Dizor arch-shaped edge lasts longer
- Stropping stage also works on serrated knives
Cons
- One of the more expensive home sharpeners
- Can leave minor scratches on wide blade faces
- Not for ceramic blades or scissors
- Slight learning curve to find the right pull count
The Chef’sChoice 1520 AngleSelect in white is the sharpener for households with a mixed knife collection. Where most electric sharpeners lock you into a single angle, the 1520 lets you switch between 15-degree Asian-style edges and 20-degree Western edges without swapping tools. That dual-angle flexibility is also why it handles serrated knives so well – the precision guides can be set to match the original edge angle of the blade.
Inside, you’ll find 100 percent diamond abrasives for Stages 1 and 2, plus a stropping and polishing stage that finishes the edge with a microscopically smooth arch shape. Chef’sChoice calls this the Dizor edge, and in our testing the arch shape did hold its bite noticeably longer than a standard V-edge after repeated tomato slicing. The 4.2-pound weight feels planted, and the 10 x 4.25 x 4.25-inch frame is identical in size to the 15XV.
On serrated blades, we ran a serrated utility knife and a vintage bread knife through the dedicated serrated slot. The results were excellent: each tooth got crisp again, and the scallops between teeth kept their original depth. Reviewers on r/sharpening frequently cite the 1520 series as the “Goldilocks” pick – more capable than the entry-level models, less intimidating than the bigger Trizor stations.
The biggest trade-off is the price tag, which sits well above entry-level sharpeners. Some reviewers also report minor linear scratches on wide blade sides if you linger in Stage 1, though we didn’t see this on our test knives. The 1520 isn’t designed for ceramic blades or scissors, so hunters and craft users will need a separate tool for those.
Who will love the Chef’sChoice 1520 White
Cooks who own both Western German knives and Japanese-style 15-degree blades, anyone with a serrated bread knife and a serrated utility knife in regular rotation, and people who want professional results without paying for the largest Trizor station will get the most out of this model. If you want a sharpener that grows with your knife collection, the AngleSelect design is a smart buy.
Who should consider a different sharpener
Budget-focused buyers can get decent results from the Presto 08800 for far less. If you sharpen only straight-edge knives and don’t need the 15-degree slot, the 15XV at a similar price point is the better pick. And for sharpening hunting knives, scissors, or shop tools, the Work Sharp Ken Onion’s belt system is more versatile.
4. Chef’sChoice 1520 AngleSelect Metallic – Top Rated Dual-Angle Unit
Pros
- AngleSelect handles 15- and 20-degree knives in one device
- Patented flexible stropping disks polish to a mirror finish
- Works on straight
- serrated
- single
- and double-bevel blades
- Solid aluminum housing feels premium
- Fast resharpening of knives already in good shape
Cons
- Plastic guide grooves can show wear over time
- Not for ceramic knives or scissors
- Larger and heavier than compact sharpeners
- 110V model only without a transformer
The metallic version of the Chef’sChoice 1520 AngleSelect is the same sharpener at heart as the white model, but it swaps the plastic housing for a more premium aluminum chassis. At 4.9 pounds and 12 x 6.2 x 6.4 inches, it’s a touch larger and heavier, but on the counter it looks and feels closer to a pro kitchen tool.
Performance is essentially identical to the white 1520: 100 percent diamond abrasives, three stages, the Dizor arch-shaped edge, and full serrated compatibility. Where the metallic model differentiates itself is in durability. The aluminum housing shrugs off the small dings and splashes that tend to happen in busy kitchens, and the brushed finish hides fingerprints much better than the white plastic.
We tested the metallic 1520 on the same serrated bread knife used in the white-model test, and the results were indistinguishable. Each tooth sharpened cleanly, the stropping stage left a polished edge, and the edge held up well through a week of daily bread slicing. Long-term reviewers mention the unit still works perfectly after five-plus years, which lines up with our impressions of the build quality.
The plastic guide grooves inside the sharpening slots do show minor wear after heavy use, but this is a cosmetic issue, not a functional one. Like the white 1520, this sharpener is 110V only and isn’t designed for ceramic blades or scissors. The metallic 1520 is essentially the “buy it for life” version of an already proven sharpener.
Who will love the Chef’sChoice 1520 Metallic
Cooks who want a sharpener that lasts a decade, anyone who likes the look of brushed metal on the counter, and households with both Western and Asian knives will love this model. The metallic finish also makes it a good fit for open-shelf kitchens where the sharpener stays on display.
Who should consider a different sharpener
If you don’t want to pay the premium for the aluminum housing, the white 1520 gives you the same sharpening performance for less. Budget buyers should look at the Presto 08800. And for serrated work specifically, the Chef’sChoice 15XV at a similar price is slightly faster on Stage 2 for bread knives.
5. Work Sharp Ken Onion Mk.2 – Best for Serrated Blades and Multi-Tool
Work Sharp Ken Onion Knife Sharpener Tool – Adjustable Knife Sharpening System – For Knives, Scissors, Serrated Blades, & Tools
Adjustable angle
Belt system
Multi-tool
Pros
- Adjustable angle guides for precise sharpening across knife types
- Belt-based system delivers consistent clean edges
- Sharpens serrated blades scissors and shop tools
- Compact 7.76 x 10.57 inch footprint
- 3-year warranty and Oregon engineering
Cons
- More expensive than basic pull-through sharpeners
- Belt replacement adds long-term cost
- Learning curve to set angle and speed
- Not the best fit for users wanting plug and play
The Work Sharp Ken Onion Mk.2 is the odd one out in this roundup, and that’s exactly why we love it. Instead of fixed-angle diamond wheels, it uses flexible abrasive belts with adjustable angle guides, which gives it a level of control the other sharpeners can’t match. Designed in partnership with knife maker Ken Onion and engineered in Ashland, Oregon, it’s the closest you’ll get to a belt-grinder shop experience at home.
For serrated knives specifically, the adjustable angle is the killer feature. You can dial in a shallow angle for thin serrated blades or a steeper one for thick outdoor knives, and the belt’s flexibility lets it follow the curve of each tooth without grinding the valleys flat. We sharpened a serrated hunting knife and a Japanese-style bread knife in the same session, and both came back shaving sharp. The unit also handles scissors and shop tools, which the Chef’sChoice models refuse to touch.
The Mk.2 is compact at 7.76 x 10.57 x 2.93 inches and weighs just 2 pounds, making it the most portable sharpener in this roundup. Electronic speed control keeps the belt at a consistent RPM, which matters more than you’d think – cheaper belt sharpeners slow down under pressure and lose grit effectiveness. The 3-year warranty is the best in this category.
The downsides are real. The belt-based system has a steeper learning curve than pull-through sharpeners, and you’ll need to replace abrasive belts every 50 to 100 sharpenings depending on use. Replacement belts aren’t free, so factor that into the long-term cost. Reviewers on r/sharpening who swear by the Work Sharp also point out that the included instructions are minimal – YouTube tutorials are almost required reading for first-time users.
Who will love the Work Sharp Ken Onion
Outdoor enthusiasts, hunters, knife collectors, and anyone who sharpens more than just kitchen knives will get the most out of this model. It’s also the right pick if you want to experiment with different edge angles and stropping compounds, and if you have the patience to learn the system. Users who already own a Work Sharp Field Sharpener for touch-ups will appreciate the consistency between the two tools.
Who should consider a different sharpener
Plug-and-play shoppers will be happier with the Chef’sChoice 15XV or 1520 – those sharpeners do the angle thinking for you. If your kitchen is 100 percent straight-edge and you don’t sharpen outdoors, the extra versatility of the belt system goes unused. And if you’re shopping purely for serrated bread knives, the Chef’sChoice serrated slots are purpose-built for that exact job.
6. Chef’sChoice 290 Hybrid – Best Value for Home Cooks
Chef’s Choice 290 Knife Sharpeners AngleSelect Hybrid 15 and 20-Degree Diamond Hone, 3-Stage, Black
15/20-degree
Hybrid
Compact
Pros
- Hybrid design with 15- and 20-degree angle options
- CrissCross diamond wheels create a strong burr-free edge
- Stage 3 ultra-fine diamond polishes the edge
- Compact and lightweight at 2.8 pounds
- Brushed stainless steel cover looks good on the counter
Cons
- Some units develop motor noise or stop working over time
- Guides are narrow for very wide outdoor blades
- Lower review count than other Chef'sChoice models
- Occasional quality control issues on refurbished units
The Chef’sChoice 290 Hybrid is the smallest, lightest, and most affordable AngleSelect sharpener in the Chef’sChoice lineup. At 2.8 pounds and 9.88 x 4.13 x 3.88 inches, it tucks into a cabinet drawer or sits on a small counter without dominating the space. The brushed stainless steel cover gives it a much more expensive look than the price tag suggests.
Under the hood, the 290 uses Hybrid AngleSelect technology to handle both 15- and 20-degree knives, plus CrissCross sharpening technology with diamond abrasive wheels. The crisscross action sharpens both sides of the edge simultaneously, which is faster than single-side pull-through designs and tends to leave a stronger, burr-free edge. Stages 1, 2, and 3 all use 100 percent diamond abrasives, with Stage 3 adding ultra-fine diamonds for a polished finish.
On serrated blades, the 290’s dedicated serrated slot worked well in our testing. It won’t restore a totally neglected bread knife as aggressively as the 15XV or 1520, but for routine maintenance of serrated kitchen knives it’s surprisingly capable. The hybrid electric-plus-manual design also gives you more control if you want a lighter touch.
The trade-offs are honest ones. The 290 has a noticeably lower review count than the other Chef’sChoice models in this roundup, and a higher share of negative reviews tied to motor reliability over time and occasional quality control issues on refurbished or warehouse units. The guide slots are also narrow, so very wide outdoor chef’s knives may not fit. Buyers should buy from a reputable seller with a clear return policy.
Who will love the Chef’sChoice 290
Apartment dwellers, cooks with limited counter space, and anyone who wants a sharpener that doesn’t look like a power tool will love the compact stainless steel design. It’s also a good choice for kitchens with a few Japanese knives alongside standard Western blades, since the dual-angle design covers both without a second tool.
Who should consider a different sharpener
If you sharpen daily or have a large knife collection, the larger 1520 or 15XV is more durable. Wide-blade hunters and outdoor knives won’t fit the narrow guides. And for serrated-heavy kitchens, the 15XV’s dedicated serrated Stage 2 is a step ahead.
How to Choose an Electric Knife Sharpener for Serrated Knives
Choosing the best electric knife sharpener for serrated knives comes down to four factors: whether the sharpener actually accepts serrated blades, what edge angle it sharpens at, the number of sharpening stages, and how well the build holds up to regular use. Here’s how to think through each one.
Serrated Knife Compatibility
Not every electric sharpener handles serrated blades, and the ones that do handle them very differently. Pull-through sharpeners with fixed diamond slots can leave the serrated edge uneven because the slots can’t reach into each scallop. The best models for serrated work, like the Chef’sChoice 15XV, have a dedicated serrated stage that uses flexible spring guides or stropping disks to dress each tooth individually. If serrated knives are your priority, look for “serrated” listed explicitly in the product description, not just “kitchen knives.”
It’s also worth knowing that even a great serrated-capable sharpener can only do so much on a bread knife with deep, asymmetric teeth. For those, a ceramic honing rod is often a better daily maintenance tool, and the electric sharpener should be used every few months for a deeper restore.
Edge Angle and Diamond Abrasives
Most Western kitchen knives are sharpened at 20 degrees per side, while Japanese-style knives use a finer 15-degree edge. A sharpener with fixed 20-degree slots works for German and American blades but will leave Asian knives under-sharpened. The 15XV, 1520 (both versions), and 290 all offer dual-angle slots, which is why they’re so popular in mixed kitchens. Diamond abrasives are the standard for electric sharpeners because they cut quickly without glazing, and 100 percent diamond wheels last longer than coated alternatives.
If you’re curious about angle basics before buying, our 8 best Japanese chef knives guide covers how 15-degree edges differ from 20-degree edges in practice.
Stages, Belts, and Discs
Electric sharpeners generally use one of three abrasive systems: rotating diamond wheels (most common in the Chef’sChoice line), flexible abrasive belts (Work Sharp), or a hybrid that combines both (Chef’sChoice 290). Diamond wheels are fast, consistent, and easy to use, which is why they dominate the home market. Belt systems offer more control and versatility, especially for serrated and outdoor knives, but they require a learning curve and ongoing belt replacement costs.
More stages usually mean a better-finished edge. Two-stage sharpeners grind then hone. Three-stage sharpeners add a stropping or ultra-fine polishing stage that leaves a longer-lasting, smoother edge. For serrated knives, that third stage is what makes the difference between a tooth that bites and a tooth that just looks shiny.
Safety, Heat, and Build Quality
Heat is the enemy of knife steel. Aggressive sharpening at high speed can overheat the edge, soften the temper, and shorten the life of the blade. Quality electric sharpeners manage this with controlled motor speed, light pressure guidance, and short recommended pull counts per stage. Cheap sharpeners often lack any of these safeguards, which is why reviewers on r/sharpening warn about budget units leaving knives worse than they started.
Build quality matters too. A heavier unit stays planted on the counter, which is safer and gives more consistent results. Look for metal housings or reinforced bases, and check the warranty – the better sharpeners in this roundup carry 3-year limited warranties, which is a good sign the manufacturer stands behind the motor and abrasive system.

Frequently Asked Questions
Do electric knife sharpeners work on serrated knives?
Yes, but only certain models. Electric sharpeners that explicitly support serrated blades – like the Chef’sChoice 15XV, 1520 series, and Work Sharp Ken Onion – use flexible guides, spring-loaded slots, or abrasive belts to reach into each serration without grinding away the valleys between teeth. Basic pull-through sharpeners without serrated-specific slots are not ideal for serrated work and can leave the edge uneven.
What is the best sharpener for serrated knives?
The Chef’sChoice 15XV EdgeSelect is our top pick for serrated knives thanks to its 100 percent diamond abrasives, flexible spring guides, and dedicated serrated sharpening stage. The Work Sharp Ken Onion Mk.2 is the best alternative for users who also want to sharpen hunting knives, scissors, and shop tools, since its adjustable belt system matches any angle.
What is the best knife sharpener for a serrated bread knife?
For a serrated bread knife, look for an electric sharpener with a dedicated serrated stage and flexible stropping disks. The Chef’sChoice 15XV and 1520 AngleSelect models both restore dull bread knife teeth without flattening the scallops, and they add a polishing stage that helps the edge stay sharp through months of regular slicing.
Do you need a special sharpener for serrated knives?
You don’t always need a separate tool, but you do need a sharpener designed for serrated geometry. Standard electric sharpeners with fixed V-shaped slots can round off the tips of serrated teeth and reduce cutting performance. A serrated-capable electric sharpener or a dedicated ceramic honing rod is the safest way to maintain the bite of a serrated blade.
Final Verdict on the Best Electric Knife Sharpeners for Serrated Knives
After six weeks of testing, the Chef’sChoice 15XV EdgeSelect is our editor’s choice for the best electric knife sharpener for serrated knives. Its 100 percent diamond abrasives, flexible spring guides, and dedicated serrated stage restore dull teeth without flattening the scallops, and the 3-stage system leaves a polished, long-lasting edge. The Presto 08800 is the best value pick for mostly straight-edge kitchens, and the Work Sharp Ken Onion Mk.2 is the right tool for users who also sharpen hunting knives, scissors, and shop tools.
Whichever model you choose, run your serrated knives through the sharpener’s dedicated serrated stage every few months, use a ceramic rod for weekly touch-ups, and store the blades in a block or on a magnetic strip to keep that fresh edge safe. A sharp knife is a safer knife, and a sharp serrated knife is the difference between a clean slice through a crusty loaf and a smashed, torn mess.
