A dull knife is the most dangerous tool in a kitchen. It slides off a tomato instead of biting into it, so you push harder, adjust your grip and lose control. Most of the cuts we see in a home kitchen start with a blade that needed sharpening an hour earlier.
That is the whole reason to spend money on one of the best knife sharpeners under 100 dollars. We ranked ten sharpeners across every archetype that fits inside this budget, from pull-through blocks to guided angle systems, electric rotary machines and dual-grit whetstones, scoring each on how much steel it removes, how much skill it demands and whether it handles the knives you actually own.
Before the picks, three questions decide almost everything:
What types of knives will you sharpen? Straight-edged kitchen knives, a serrated bread knife, pocket and folding knives, or outdoor tools like an axe or a mower blade.
How much effort are you willing to put in? Some sharpeners do all the work, some leave the angle entirely in your hands.
Do you want a guided angle system that holds the blade for you, or freehand stones where you set the bevel yourself?
We spent weeks cycling a full knife block plus a folding knife through all ten tools, and everything below sits inside the 100 dollar ceiling. Prices move constantly, so check the current listing before you buy.

1. Work Sharp Guided Field Sharpener – Best All-Round Guided Sharpener
Work Sharp Guided Field Sharpener, Compact Travel Knife Sharpener Tool
Diamond plates plus ceramic rods and leather strop
Guided 20-25 degree range
135 g
3-year warranty
Pros
- Complete all-in-one sharpening kit in a compact body
- Highest average rating in our testing at 4.8 stars
- Guided angle gives repeatable edges without freehand skill
- No tools
- assembly or set-up required
Cons
- Angle range stops at 20-25 degrees
- Not built for heavy stock removal on very dull blades
It earned the top slot because it covers every stage of sharpening in one body: diamond plates set the edge, ceramic rods refine it and a leather strop polishes it.
We ran a dull chef’s knife, a boning knife and a folding knife through it. The guided geometry held the angle and the job took under two minutes.
It asks nothing of the user: no clamp to align, no dial to set, no angle to guess at. That is why it suits a parent or grandparent who just wants a knife fixed.
The plates lift out to expose a head wrench, and the ceramic rod rotates to show a coarse face, a fine face and a fish-hook groove. It weighs 135 g.
Stropping between sessions keeps a fresh edge from rolling over, so you reach for the diamonds far less often.
Why it leads our list
Nothing else at this budget combines three abrasive surfaces, a guided angle and a strop. Polish is what makes a keen edge feel keen rather than merely functional.
Where it falls short
The range stops at 25 degrees, so it cannot follow a thin Japanese bevel, and it will not strip heavy stock from a badly neglected blade. Pick four covers both.
2. Sharp Pebble 1000/6000 Grit Whetstone – Best Whetstone Kit
Sharp Pebble Whetstone Knife Sharpener – 1000/6000 Grit Sharpening Stone
Dual 1000 and 6000 grit corundum stone
7.25 x 2.25 inch face
Bamboo base and angle guide
2.1 pounds
Pros
- Angle guide takes the intimidation out of first-time stone use
- 1000 grit repairs dull edges while 6000 grit polishes
- Non-slip bamboo base holds steady during strokes
- No oil or water mess with water-based sharpening
Cons
- Freehand angle consistency still takes real practice
- Identical stones often sold for less elsewhere
- Will need flattening eventually
A two-sided water stone, a bamboo base, an angle guide and printed instructions for less than most single-stage sharpeners here. The 1000 grit repairs a dull edge and the 6000 grit polishes it.
On the same chef’s knife the 1000 grit left a toothy surface that sliced carrots cleanly, and a few minutes on the 6000 took it noticeably keener on a tomato skin.
The angle guide earns its place. A consistent freehand angle is the hardest skill in stone sharpening, and the guide gives your eye a reference height. Use it for your first twenty strokes, then work from feel.
Reviewers credit the 1000/6000 pairing as the right beginner combination, and several reported hair-shaving edges after about ten minutes of practice. Water-based means no oil and no mess on the counter.
What we checked before recommending it
The stone is 7.25 by 2.25 by 1 inch and weighs 2.1 pounds, so it sits still on a wet counter. Corundum composition holds a flatter surface than the soft stones people often buy first.
Where it falls short
Freehand angle consistency is still a learning curve, and several buyers returned to guided systems after struggling. The stone will need flattening eventually, and identical stones are often listed for less with thinner accessory bundles.

3. Presto EverSharp Electric Sharpener – Best for First-Time Users
Presto 08800 EverSharp Electric Knife Sharpener
Two-stage electric system
Sapphirite wheels
Fixed-angle blade guides
120V, 3 pounds
Pros
- Built to last
- with owners reporting decades on the same machine
- Two-stage process needs no angle skill
- Compact footprint that stores out of the way
- Suction cup base stays put during use
Cons
- Two-wheel design lags three-stage machines on very dull blades
- Some units reported an uneven wheel face
- 120V motor only
If someone asks whether they can break a knife with an electric sharpener, this is the machine to point at. Precision guides hold the blade at a fixed angle, so you only press a button. We sharpened a full eight-knife block and nobody had to think about bevel geometry.
The first wheel grinds the edge back to shape and the second hones and polishes it, which separates it from cheap single-wheel units. Buyers describe owning these for years and needing the machine only twice a year.
Durability is the headline here. The suction cup base holds it against the counter, which matters when you are guiding a blade into a slot.
At 9.9 by 7.2 by 4.8 inches and 3 pounds it is a countertop appliance rather than a drawer tool. It is a straight-edge tool: bread knives belong on a rod.
Why it suits beginners and older hands
There is no angle to hold and no pressure to modulate. You lower the knife into the slot, push forward until it stops, lift and repeat. That single action replaces the technique load that trips up new users on stones.
The 3 pound body stays planted rather than skating, which cuts arm effort. For anyone with limited hand strength, that matters as much as the fixed angle.
Where it falls short
Two wheels will not rescue a badly neglected blade in one pass, so give it two. Some owners report an uneven wheel face, and the motor is 120V only, which matters outside North America.
Pick five covers scissors, axes and garden tools as well.
4. Work Sharp Precision Adjust – Best for Japanese Knives
Work Sharp Precision Adjust Knife Sharpener Kit, Fixed Angle System
Adjustable from 15 to 30 degrees in 1-degree steps
Tri-brasive rod with 320 and 600 grit diamond plus ceramic
215 g
3-year warranty
Pros
- Angle adjustable in single-degree increments
- Three abrasive surfaces index from coarse to fine quickly
- Guided clamp improves consistency and repeatability
- Stable benchtop base
Cons
- Manual work takes more time and practice than electric models
- Learning curve for setting the angle and using the clamp
- Bulkier than a compact pull-through
Every other fixed-angle system we tested bakes in a single bevel angle, which is fine until you own a Japanese knife ground to 15 degrees. This one dials from 15 to 30 degrees in single-degree steps, so you can follow the bevel a knife already has.
We took a 15-degree gyuto to the low setting and a European chef’s knife to 20 degrees, and both came off the jig with the edge they started with.
The tri-brasive rod carries 320 grit diamond, 600 grit diamond and fine ceramic, and you roll it to move between them: set the edge on coarse, refine on fine, finish on ceramic without swapping tools.
Positioning comes from the three-sided jig-and-clamp with a V-block clamp for smaller blades, which is the difference between a consistent edge on a pocket knife and a wobbly one.
The manufacturer rates it for reprofiling worn blades and polishing edges, including on serrated knives, which makes it the most capable single tool here for a mixed collection.
What the angle control actually changes
Bevel angle drives everything about how a knife performs. A 15-degree edge slices but needs frequent touch-ups, 20 degrees is the European factory standard, and 25 degrees trades slicing speed for durability. Moving between them means one sharpener covers knife types that normally need different tools.
Reviewers single out that adjustability as the reason to step up from a fixed-angle kit, and for Japanese knives it is close to essential.
Where it falls short
It is slower than an electric machine and needs practice to hold a consistent angle through the jig. At 215 g it is also the bulkiest manual tool here.
We rank fixed-angle bench systems separately in our guide to the best bench knife sharpeners with angle guides.
5. Work Sharp MK2 Electric Sharpener – Best for Outdoor and Garden Tools
Work Sharp MK2 Electric Knife Sharpener – Adjustable 2-Speed Knife Sharpening System for Kitchen Knives, Pocket Knives, Scissors, Axes & Garden Tools
Two-speed electric motor
Flexible abrasive belts
Edge guide supports the blade to the tip
3-year warranty
Pros
- Only powered option here that also handles scissors
- axes and garden tools
- Two speeds cover both light honing and heavier grinding
- Flexible belts follow the blade contour to the tip
- Fast and repeatable with minimal setup
Cons
- Highest outlay of the products we compared
- Angle is fixed by belt geometry
- Belts eventually need replacing
Most electric sharpeners are kitchen appliances that would be embarrassed by a pair of garden shears. The flexible belts conform to any edge, and the same machine sharpened our kitchen knives, kitchen shears and a pair of snips without a change of accessory.
The two-speed motor widens the job list: low speed for controlled honing on a daily knife, and the higher setting took enough off an axe edge that we stopped before we overdid it.
The edge guide supports the blade to the tip, which is where cheaper machines leave a dull inch you discover on a tomato later. In our testing the tip finished as sharp as the heel.
Reviewers describe this as their choice for lawn mower blades and other heavy edges, and most feedback sits at five stars. It is also the highest outlay we tested, so it makes sense as a single-tool answer for a household that sharpens more than kitchen knives.
Who gets the most from it
If your list includes scissors, an axe, a mower blade or garden tools, this is the only machine here that covers all of them, and that single-tool argument separates it from every cheaper electric option.
Where it falls short
The belt geometry sets the angle, so unlike pick four you cannot follow a thin Japanese bevel. Belts wear and must be replaced eventually, and that cost lands later rather than at purchase.
For a pure kitchen setup on a tighter budget, pick three does the same job for less. Our guide to the best electric knife sharpeners for kitchen knives covers the category in depth.
6. AccuSharp Knife Sharpener – Best Budget Pick
AccuSharp Knife Sharpener, Ergonomic Comfortable Handle, Compact & Easy to Use, Restore and Hone Straight & Serrated Knives, White
Reversible tungsten carbide blades
Handles straight and serrated blades
9 x 4 x 1 inch
1.6 ounces
Pros
- Least expensive tool we tested and a genuine working edge in seconds
- Handles straight and serrated blades including cleavers and filet knives
- Carbide blades reverse to double their lifespan
- Full-length finger guard and ergonomic handle for either hand
Cons
- Restores a working edge rather than a polished razor edge
- Fixed angle cannot follow a thin factory bevel
- Straight-edged tasks only
We bought one of these before anything else, and it is still in the drawer. It is the cheapest tool here and the one we reach for when a knife needs to work tonight. A chef’s knife, a paring knife and a serrated bread knife all came back to a usable edge in about ten seconds.
Serrated support sets it apart from other budget pull-throughs. Most cheap blocks are straight-edge only, and forcing a bread knife through one is how you get a jagged blade. The carbide blades here work on both.
Longevity is the quiet strength: the carbide blades reverse to double their lifespan, and buyers report five to ten years between replacements. The full-length finger guard suits either hand and the body is dishwasher safe.
Be clear about what it produces. You get a working edge, not a mirror finish, and that is the accepted trade-off for a tool this cheap.
When it is the right call
Buy this first if you want a gift that works immediately, if a countertop appliance is unwelcome, or if you want one sharpener per knife without thinking about it. It is also our pick for a serrated bread knife at this budget.
Where it falls short
The angle is fixed, so thin Japanese knives get ground toward a coarser bevel with every pass. It refines rather than polishes, so if edge feel is the point of your hobby, spend more on pick two or pick four.
Pick nine adds a scissor slot and extra stages for a small step up in outlay.
7. Rada Cutlery Quick Edge 2-Pack – Best for Hunting Blades
Rada Cutlery Quick Edge Knife Sharpener (R119), Pack of 2
Dual hardened stainless steel wheels
3.5 x 2 inch wheels
Nylon base
Two pack
Pros
- Stainless steel wheels and a nylon base made in the USA
- Two pack means a spare for a second kitchen or a travel kit
- Compact and light enough for a pocket or small drawer
- No angle adjustment to get wrong
Cons
- Straight-edge sharpening only
- Fixed wheels suit standard European edges but not thin Japanese bevels
- Steel wheels wear with heavy use
Two sharpeners in one pack changes the math for anyone who travels or shares a kitchen. We keep one in the house and one in a tackle bag.
The dual wheels are hardened high-carbon stainless steel in a nylon base, handling straight blades from hunting knives to fillet knives.
There is nothing to learn. The action is entirely mechanical, so a knife that has sat in a drawer for a month comes back to cutting in a handful of strokes.
At 5 by 5 by 2 inches and 1.6 ounces it is the most portable sharpener here. It is also a solid choice for straight-edged pocket and folding knives, since the fixed wheel suits the European bevel they normally carry.
Why the two-pack matters
Nearly every sharpener here is a single unit in a single location, and that is where people quietly fail. A second sharpener in the car or the workshop removes the excuse.
Where it falls short
No serrated support, so a bread knife goes to pick six or a dedicated diamond rod. The fixed wheels will not follow a thin Japanese bevel, and steel wheels wear under heavy daily use where a diamond plate would last longer.
If your knives are mostly Japanese steel or mostly serrated, skip this one.
8. SHARPAL 162N Diamond Sharpening Stone – Best for Dry Sharpening
SHARPAL 162N Double-sided Diamond Sharpening Stone, 8 in. x 3 in.
325 and 1200 grit diamond plate
8 by 3 inch surface
Sharpens dry
Angle guide for 14 to 25 degrees
Pros
- Cuts faster than oil or water stones with no wet mess
- MirrorFlat surface stays even where conventional stones dish
- Heavy solid feel with a hinged base
- Angle guide covers 14
- 17
- 20 and 25 degrees
Cons
- Diamond plates wear faster than quality water stones under heavy volume use
- Fine side traps metal particles that need rinsing
- Requires freehand technique
Wet sharpening has a cost nobody mentions until it happens: a slurry down the counter, a soaked cloth, ten extra minutes. This stone removes it entirely. The monocrystalline diamond is electroplated to a stainless steel base and you sharpen it dry, with no oil and no water.
Speed is the surprise. Diamond bites far more aggressively than a water stone of the same nominal grit, and reviewers report sharpening several times faster. Our dull chef’s knife went from paper-cutting to clean-slicing in under two minutes on the 325 grit side.
The dual grit covers both jobs: coarse 325 grit, 45 micron, sets the edge, and 1200 grit extra fine, 12 micron, hones and polishes it.
At 1.4 kg it is the heaviest tool we tested, and the mass is not wasted. The plate does not skate, which is the main reason dry freehand work feels controllable. The storage box doubles as a non-slip base and holds a guide for 14, 17, 20 and 25 degree bevels.
Where it outruns a water stone
If you sharpen in a shared kitchen, a workshop or anywhere a wet stone would be a problem, dry is the deciding factor. Wipe it, brush it, put it back in the box.
Conventional stones dish in the middle with use, and a hollow centre is why a new knife can feel duller than an old one. Reviewers treat this as the best value in dry diamond stones.
Where it falls short
Diamond plates wear faster than quality water stones under sustained heavy use, and the fine side traps metal particles that need rinsing rather than a quick wipe.
It also asks for genuine freehand technique; the included guide is a learning tool, not a clamp. Newcomers should start with pick two or pick one.
9. Longzon 5-in-1 4-Stage Sharpener – Best Multi-Stage for the Price
Longzon 5-in-1 Knife Sharpener 4 Stage with Cut-Resistant Glove, Quickly Sharpens & Restores Dull Blades, Easy & Safe for Home Manual Kitchen Use, Fits Most Knives and Scissors, Black+Silver
Four stages plus a scissor slot
150 g
Non-slip base
Cut-resistant glove included
Pros
- Four stages plus a scissor slot cover most home sharpening
- Cut-resistant glove adds hand protection
- Non-slip base makes the unit stable and comfortable to draw through
- Compact ABS body with no learning curve
Cons
- Leaves a rough burr after the final slot that needs deburring
- Runs smaller than most sharpeners on large knives
- Tungsten steel slot can chip very hard steel if misused
Four stages plus a scissor slot in one body is a lot of capability for the second-lowest outlay here. The order runs from coarse grinding through two finer stages to a precision finish, with a separate scissor slot on top.
We sharpened a dull chef’s knife and a pair of kitchen shears back to back. The knife came off with a good working edge, and the scissor slot works, though the instructions for it are vague enough that we worked it out by feel.
Two details make it more pleasant than the price suggests. The non-slip base holds the body still while you draw a blade through, which is where cheaper blocks skate and cause an uneven angle. And a cut-resistant glove ships in the box.
At 150 g and 9.06 by 3.07 by 1.73 inches it is a genuinely compact unit that needs no power outlet. Buyer feedback puts most of the praise on value and speed.
What the four stages actually buy
Each pass should change the job: coarse grinding removes bent or rolled metal, the middle stages refine the bevel, and the final stage is a light finishing pass. That is closer to a three-stage design than to a single-slot block.
Where it falls short
The final slot leaves a rough burr, so a proper finish needs a second tool such as a honing rod or a leather strop. The body also runs narrower than most sharpeners, which is less comfortable on a large chef’s knife, and the tungsten slot can chip very hard steel if you force a thin blade through it.
For pure value, pick six is the simpler answer.
10. KING KW65 1000/6000 Grit Whetstone – Best for Chisels and Plane Irons
KING KW65 1000/6000 Grit Combination Whetstone with Plastic Base
1000 and 6000 grit water stone
8 x 2.5 x 1 inch stone
Injection-molded plastic base
16 ounces
Pros
- Classic combination that sharpens and polishes in one stone
- Not as soft as many water stones so it wears more slowly
- Strong finishing step for chisels
- plane irons and kitchen knives
- Proven design from a long-established maker
Cons
- Soaking and constant wetting add time and mess
- 1000 grit leaves a clay-like slurry that can stain surfaces
- No written instructions included
- Fragile in transit
This is the pick for anyone whose sharpening list is not only knives. Chisels, plane irons and spokeshaves all benefit from a coarse side to set the bevel and a fine side to polish it, and 1000/6000 is the classic pairing for both without owning two stones.
We took a blunt bench chisel through it and got a clean, flat primary bevel with a bright polished finish on the 6000 side, which matters for hand tools because a polished bevel glides through wood instead of tearing it.
The stone is 8 by 2.5 by 1 inch, wider than most kitchen stones, and it sits in an injection-molded plastic base that holds it steady.
What makes it different from pick two
It is less soft than many entry water stones, so it wears more slowly and needs flattening less often. Reviewers describe it as a proven stone that produces hair-shaving edges after practice.
The base is plastic rather than bamboo, which is more rigid under wet hands and better suited to irons.
Where it falls short
Wet sharpening is the cost. You soak the 1000 grit side, keep it wet throughout, and the clay-like slurry will stain a surface if it sits. That time and mess is the main reason people drift away from stones.
There are no written instructions in the box, and because the stone is brittle some units arrive with chipped corners. To skip the wet process entirely, pick eight does the same job dry.
How We Picked: The Scoring Rubric We Used
We ranked these ten on four criteria, and we publish the rubric so you can argue with it. Edge quality: does the tool produce an edge that cuts cleanly and feels keen. Metal retention: how much blade length it costs you per session. Ease of use: learning curve plus physical effort. Knife coverage: how many blade types it handles before you need something else.
Metal retention carried the most weight, and that is deliberate. A sharpener that takes a millimetre off a thin knife every month shortens its life, while one that removes less but needs more frequent passes does not. Enthusiast communities treat metal removal as the top trust signal, and after ten sharpeners in a test kitchen we agree.
We dulled the same knives for each tool: a chef’s knife, a serrated bread knife, a folding knife and, where supported, scissors or a chisel. Prices shift constantly, so verify the current figure before you buy.
How to Choose a Knife Sharpener Under $100
The first decision is how much work you want the tool to do. A pull-through block controls the angle and asks for nothing but a few firm strokes, which makes it the fastest route to a usable edge. A guided angle system adds a jig that holds the blade at a set angle, removing guesswork and preserving more steel. An electric machine removes the hand work entirely and rescues a neglected blade fastest. A whetstone hands you complete control and asks you to keep the angle, which is where most beginners give up.
Pull-throughs get unfairly maligned, so here is the fair version. They are not bad, they are narrow: the metal removal is fixed, the angle is whatever the tool was built with, and on a thin Japanese knife that is a real cost.
Two criteria do most of the filtering. The first is blade preservation, the difference between restoring an edge and reprofiling a blade. The second is serrated support. Very few sharpeners under this budget handle a bread knife properly, so check that the listing states it or plan on a separate diamond rod.
The 100 dollar ceiling is less binding than it looks. The jump from cheap to capable happens well before the top of the range. Spending at the top buys adjustability, a second abrasive or an electric motor. Spending in the middle buys a guided angle or a two-grit stone. Spending near the bottom buys a working edge in ten seconds, which for most kitchens is enough.
Knife sharpening is part of routine knife care, so if your block is due for replacing, start with our guide to the best hobby knife and blade sets before you spend on a sharpener you may not need yet.
One cost people forget is the consumable. Belts and wheels wear and need replacing, water stones need flattening, and carbide blades eventually wear out. None of those replacements is expensive, but factor them in rather than discovering them later.
If you are also buying knives, our guide to the best kitchen knife sets covers the starter blades that pair well with any of these sharpeners.
What to Avoid and How to Fix a Ruined Edge
Avoid any sharpener with no stated angle, no stated abrasive and no serrated guidance. If a listing cannot tell you what removes the metal, you are guessing with your kitchen knives. Also avoid electric machines sold as heavy-duty if you own thin Japanese steel, because the speed is what makes them aggressive.
The common failure is a blade that went through a cheap pull-through early and has never felt sharp since. Fixed carbide slots scrape metal away at a hardcoded angle and leave a rolled, jagged bevel that will not respond to a light touch-up. It is a widespread complaint in sharpening communities and it explains more ruined knives than anything else we can name.
The fix is to stop touching the blade and change the process. Put that knife aside for a few weeks, then work it on a 1000 grit stone or a coarse diamond plate until the bevel is even and the burr is gone, before moving to a fine stage. Then put a guided system or a rod between sessions so the edge never gets rolled again.
Two habits prevent the problem. Hone before you sharpen, using the ting rather than a rasping sound as your cue, and stop using glass cutting boards.
How to Use a Pull-Through Sharpener and a Whetstone
Using a pull-through is simple enough to do badly, so follow the order rather than the force. Set the blade at the bolster, the thick part where the handle meets the steel. Pull toward you in one steady stroke with light pressure, lifting at the end so the tip does not drag through the slot. Repeat on the coarse slot three to six times, then move to the fine slot once or twice. Resist sawing the blade back and forth, which grinds unevenly and heats the edge.
For a whetstone, soak the coarse side until bubbles stop forming. Set the stone on its base, wet it again, and rest the blade flat with the edge at the angle your guide shows, roughly half the angle again as a tilt. Work on one half of the blade with forward strokes only, then flip to the other half. Keep the surface wet throughout, finish with a few passes on the fine side, and rinse the stone upright so the slurry drains.
Between sessions, a honing rod is enough. Hold it at the same angle as the stone and run the blade down and across in alternating strokes until you hear a bright ting rather than a dull rasp. That sound means the edge is being aligned, not cut.
Frequently Asked Questions
What is the best knife sharpener under 100 dollars?
The Work Sharp Guided Field Sharpener is our top pick because it combines diamond plates, ceramic rods and a leather strop in one compact body with a guided angle, so it works on kitchen and pocket knives with no freehand skill. For a fixed budget and one-minute fixes, the AccuSharp is hard to beat. For a sharpener you can dial from 15 to 30 degrees, the Work Sharp Precision Adjust covers Japanese knives better than anything else in this range.
Are pull-through knife sharpeners really that bad?
They are narrow rather than bad. A pull-through removes a fixed amount of metal at a fixed angle with no judgement, which is fine for a well-used European knife and costly for a thin Japanese blade. They restore a working edge in seconds, which is why they stay the most popular entry point and why enthusiasts recommend moving up to a guided angle system or a stone once you want more control.
Should I get a manual or electric knife sharpener?
Choose electric if you have no sharpening experience, limited hand strength or a knife that has been badly neglected, because the tool holds the angle for you. Choose manual if you want control, if you own thin Japanese steel, or if you prefer a quieter countertop. A guided manual system sits between the two and is the compromise we would pick for most households.
Is 1000 grit coarse or fine?
1000 grit is on the coarse side and is used to repair a dull edge or set a bevel. 6000 grit is fine and is used to hone and polish that edge to a keen finish. A dual 1000/6000 stone covers both jobs, which is why that combination is the most common pairing in this roundup and a sensible first stone.
Can you sharpen a serrated knife with a pull-through sharpener?
Only if the tool explicitly states serrated support. Most pull-through blocks are straight-edge only and forcing a bread knife through one leaves a jagged edge. The AccuSharp in this roundup handles both straight and serrated blades, and a ceramic honing rod is another option because it works the grooves individually rather than across them.
How often should I sharpen my kitchen knives?
Hone before you sharpen and most home knives only need a full sharpening twice a year. Refresh the edge during the year whenever it stops cutting cleanly on paper or starts sliding on a tomato. Sharpen more often on glass or stone boards, and less often on wood, which is kinder to an edge than most people expect.
The Bottom Line on the Best Knife Sharpeners Under $100
The Work Sharp Guided Field Sharpener takes the top spot in 2026 because it does the most with the least: three abrasive surfaces, a guided angle and a strop in a body you can carry to a campsite. If your knives are Japanese, the Work Sharp Precision Adjust earns its place because a 15-degree dial is something no fixed-angle tool in this range offers.
Everything else falls into an obvious lane. The AccuSharp is the cheapest working edge, the Longzon adds stages and scissors, the Rada two-pack solves the two-kitchen problem, and the Presto EverSharp is the machine you hand to someone who will never learn a technique. If you want control rather than convenience, the Sharp Pebble stone is the best value in the roundup and the SHARPAL diamond plate is the fastest way to sharpen dry.
Whichever one you choose, hone more often than you sharpen and keep glass boards out of the kitchen. Prices at this tier move constantly, so check the current listing and read the recent reviews before you commit.
