The best knife sharpener in NZ overall is the SHARPAL 198H below, thanks to a three-stage electric system that sharpens both sides of the blade at once, taking a dull knife from repair to a finished edge with no technique to learn.
A sharp knife makes almost every kitchen task faster and safer, but the right sharpener depends on the knives you own and how much control you want over the edge. This guide compares seven knife sharpeners sold in NZ, from simple pull-through designs and an electric three-stage unit to a four-sided whetstone kit and a magnetic rolling sharpener, each picked for a different kitchen and skill level.
Many of these sharpeners work well alongside other kitchen upgrades. If you are rounding out the rest of the kitchen, a good set of food processors covers the prep side of things that a sharp knife can’t.

How We Chose
Every sharpener here was confirmed as a live, in-stock listing that delivers to New Zealand at the time of research. The design and feature detail below comes from each product’s own listing, with doubtful or thin claims called out in the cons rather than repeated. Each pick was given a distinct role so the shortlist covers different sharpening styles and skill levels rather than repeating the same mechanism.
The Best Knife Sharpeners in NZ
1. SHARPAL 198H Electric Knife Sharpener – Best Overall
The best knife sharpener in NZ overall is the SHARPAL 198H, because its three-stage electric system sharpens both sides of the blade at once, so even a cook with no sharpening experience gets an even edge in a few passes.
It is a mains-powered benchtop unit, about 22cm long and 0.7kg, finished in white. The three slots run from a monocrystalline diamond stage for a dull or damaged edge through to ceramic for finishing, and each slot grinds both bevels of the knife at the same time, which keeps the two sides matched. SHARPAL lists it for most double-bevel straight-edge knives and for serrated blades, and a built-in tray collects the metal filings so they don’t end up on the bench.
In use you switch it on and draw the blade through each slot in turn, with no clamp or angle to set. The brand quotes running noise under 65 dB, which is quieter than many electric sharpeners, and says the grinding speeds are preset so the blade is not overheated or de-tempered. It is backed by a 3-year limited warranty from a sharpening specialist that has an Australian branch.
The trade-off is the one Consumer NZ flags for every electric sharpener: a motorised stage removes metal faster than a stone, so it is best used when a knife is genuinely dull rather than as a daily habit. It also needs a power point and more bench or cupboard space than a pull-through, and the angle is fixed, so single-bevel Japanese knives are not a good match.
Pros
- Sharpens both sides of the edge at once for an even result
- No skill or angle setting needed
- Diamond and ceramic stages cover repair through to finishing
- Filings collector and 3-year limited warranty
Cons
- Removes more metal than a stone, so use it sparingly
- Needs mains power and more storage space
- Fixed angle, double-bevel knives only
Key specs: Electric 3-stage sharpener, monocrystalline diamond and ceramic abrasives, sharpens both sides at once, straight-edge and serrated knives, under 65 dB (claimed), filings collector, 22 x 10.5 x 7.1cm, 0.7kg, 3-year limited warranty.
2. Mitsumoto Sakari 3-Stage Adjustable Knife Sharpener – Best Budget Pick
The best budget knife sharpener in NZ is the Mitsumoto Sakari 3-stage sharpener, because it adds an adjustable angle, something most basic pull-through sharpeners leave out, while keeping the simple pull-through action.
It is a lightweight ABS plastic unit, about 26cm long and 252g, with a handle at one end and a silicone non-slip pad underneath to hold it on the bench. There are three V-shaped slots: a coarse slot for repairing a dull edge, a fine slot for polishing, and a third slot for scissors and for removing the burr left after sharpening.
What sets it apart at this level is a dial with five angle settings between 15 and 24 degrees, so you can sharpen a thin Japanese-style knife closer to 15 degrees and a heavier Western chef’s knife closer to 20 without buying a second tool. Using it is the usual routine: set the angle, hold the handle, and draw the blade through the coarse slot and then the fine slot a few times.
The listing says little about what the abrasives are made of, and the brand has a much smaller review base than the bigger names in this list, so expectations should sit at a good everyday sharpener rather than a precision tool. Like any pull-through design, it also takes more metal off than a stone if it is overused.
Pros
- Five angle settings from 15 to 24 degrees
- Separate coarse and fine slots plus a scissors slot
- Silicone non-slip base and handle
- Light and easy to store
Cons
- Listing doesn’t say what the abrasives are made of
- Smaller review base than the bigger brands here
Key specs: Manual pull-through sharpener, 3 slots (coarse, fine, scissors and deburring), adjustable 15-24 degree angle in 5 steps, silicone non-slip base, ABS plastic, 26 x 5 x 7cm, 252g.
3. BRITOR 4-Sided Whetstone Sharpening Kit – Best for Precision Sharpening
The best knife sharpener in NZ for anyone who wants full control over the edge is this four-sided whetstone kit, because two double-sided stones take a blade from chip repair at 400 grit through to a polished 8000-grit finish.
The kit is built around two combination waterstones, one 400/1000 and one 3000/8000, which sit in a bamboo base with non-slip rubber feet. Around them you get a clip-on angle guide, a flattening stone to keep the stones level, a leather strop with green polishing compound, a honing guide for chisels and a pair of cut-resistant gloves. It is a complete bench setup rather than a single stone, and at about 2.6kg it is the heaviest pick here.
The stones only need water, not oil. A typical session starts on the 400 side for chips or a very dull edge, moves to 1000 to set the edge, then 3000 and 8000 to refine and polish, and finishes with a few strokes on the strop. Because the four grits cover the full range, the same kit suits kitchen knives, pocket knives, chisels and plane blades.
This is still the slowest, most hands-on option in the list. The angle guide helps, but results depend on holding a steady angle and pressure, and there is a learning curve before the finer grits make a visible difference. Coarse stones also dish with use, which is what the flattening stone is for, so expect a little upkeep.
Pros
- Four grits from 400 to 8000 cover repair and polish
- Flattening stone, strop, angle guide and gloves included
- Water only, no honing oil needed
- Also handles chisels and plane blades
Cons
- Steeper learning curve than any pull-through or electric sharpener
- Slowest method in this list
- Heavy kit that needs bench space
Key specs: Two double-sided waterstones (400/1000 and 3000/8000 grit), bamboo base with non-slip rubber, angle guide, flattening stone, leather strop and polishing compound, chisel honing guide, cut-resistant gloves, approx. 2.6kg.
4. Billord Rolling Knife Sharpener Kit – Best for Angle Control
The best knife sharpener in NZ for consistent angle control without the learning curve of a whetstone is this rolling sharpener kit, because a magnetic block holds the blade at a fixed 15 or 20 degrees while you roll the disc along the edge.
It is a two-part system: a magnetic angle block with 15 and 20 degree faces, and a handheld roller with a disc at each end, one diamond-coated for repairing nicks and setting the edge and the other ceramic for finishing. The listing gives the grits as 400 and 1000. The knife clamps to the block by magnet, so there is no freehand angle to hold, and the whole kit packs into the supplied case.
Use is simple: fix the knife to the block on the 15 degree side for thin Japanese-style blades or the 20 degree side for sturdier Western knives, run the diamond disc along the edge several times, then turn the roller round and finish with the ceramic disc. The brand says the block takes blades from thin paring knives up to heavy cleavers.
The finest grit is 1000, so the finish is a good working edge rather than the mirror polish a 6000 or 8000 stone gives. Rolling sharpeners also take longer per knife than a pull-through, and the magnet only holds steel, so ceramic knives are not a good fit despite the broad compatibility claims in the listing.
Pros
- Magnetic block locks in a 15 or 20 degree angle
- Diamond and ceramic discs on one roller
- No freehand technique needed
- Compact kit with storage case
Cons
- 1000 grit is the finest stage, so no high polish
- Slower per knife than a pull-through
- Magnet holds steel blades only
Key specs: Rolling sharpener with magnetic angle block (15 and 20 degrees), diamond (400 grit) and ceramic (1000 grit) discs, storage case, approx. 725g.
5. 4-in-1 Knife and Scissors Sharpener – Best for Knives & Scissors
The best knife sharpener in NZ for a drawer that holds both knives and scissors is this 4-in-1 tabletop sharpener, because it combines a three-stage knife sharpener with a scissors position in one small unit.
It is a light plastic tabletop unit, about 21cm long and 250g, with a contoured body to grip and a non-slip base. The knife side follows a three-stage sequence: tungsten carbide rods set a new edge on a dull blade, then two ceramic stages restore and refine it. The listing sells it as a 4-in-1 knife and scissors sharpener, with the fourth position for scissors.
Using it is a matter of holding the body down on the bench and drawing the blade through each slot a few times, coarse to fine. Cleaning is a wipe with a damp cloth. It is about as simple as a sharpener gets, which suits a household that just wants dull kitchen knives and scissors working again.
The maker states that it is for fine-edge knives only and not for serrated blades, so bread knives need another tool. The listing also gives little detail on the scissors position beyond the name, and this is a lesser-known brand, so treat it as a practical everyday tool rather than one for premium knives.
Pros
- Three knife stages plus a scissors position
- Non-slip base and contoured grip
- Very light and easy to store
- Wipe-clean
Cons
- Not for serrated knives
- Little detail on the scissors stage
- Plastic build from a lesser-known brand
Key specs: 4-in-1 tabletop sharpener, tungsten carbide stage plus two ceramic stages for knives, scissors position, non-slip base, approx. 207 x 95 x 25mm, 250g.
6. LYMI 4-Stage Knife Sharpener with Cut-Resistant Glove – Best 4-in-1 Kit
The best 4-in-1 knife sharpening kit in NZ is the LYMI 4-stage sharpener, because it pairs four sharpening stages with a cut-resistant glove, which makes it a sensible all-in-one buy for a first sharpener.
It is a compact handheld pull-through sharpener with a non-slip base, finished in red. The four stages run coarse, medium, fine and extra fine, and LYMI lists it for stainless and hard steel kitchen knives, large knives, pocket knives and scissors, with the title also claiming it works on ceramic blades. A cut-resistant glove comes in the box for the hand that steadies the sharpener.
Use is the standard pull-through routine of placing the blade in a slot and drawing it through a few times, working from coarse to extra fine. With four steps rather than three, there is a finer finishing stage than the basic 3-stage picks in this list, and the glove is a real safety extra for anyone nervous about the blade slipping.
This is a newer listing with only a handful of reviews so far, so there is less owner feedback to go on than for the other picks. The ceramic-knife claim is worth treating with caution because the listing doesn’t say which stage, if any, is diamond, and as with any fixed-angle pull-through, it is not ideal for thin premium Japanese knives.
Pros
- Four stages from coarse to extra fine
- Cut-resistant glove included
- Listed for knives and scissors
- Non-slip base, compact size
Cons
- Few owner reviews so far
- Ceramic-knife claim isn’t backed up in the listing
- Fixed angle
Key specs: 4-stage manual pull-through sharpener (coarse, medium, fine, extra fine), listed for knives and scissors, non-slip base, red finish, approx. 230 x 78 x 44mm, includes 1x cut-resistant glove.
7. SHARPAL 191H Pocket Knife and Scissors Sharpener – Best for Everyday Touch-Ups
The best knife sharpener in NZ for everyday touch-ups is the SHARPAL 191H, because it is small enough to live in a drawer, locks to the bench with a suction base, and takes seconds to bring a knife back.
It is a pocket-size three-stage sharpener, about 7cm square and 86g. The first slot uses tungsten carbide blades to set a quick edge, the second uses ceramic for fine honing, and a separate carbide slot handles scissors. A switch on top engages the suction base, which grips a smooth benchtop firmly enough that you don’t need to hold the unit while sharpening, keeping your free hand away from the blade.
SHARPAL lists it for straight and serrated kitchen knives as well as scissors. It is built for quick maintenance: a few pulls through the ceramic slot before cooking keeps a working edge in shape, and the carbide slot is there for when a knife has gone properly dull. The brand backs it with a 3-year warranty.
The suction base needs a smooth, non-porous surface, so it won’t hold on timber or textured benchtops. Carbide slots also remove metal quickly, so leaning on that stage too often will wear good knives faster than a stone would, and the small body takes a steady hand with a long chef’s knife.
Pros
- Suction base means no hand is needed to hold it
- Carbide, ceramic and scissors slots
- Very small and light
- 3-year warranty
Cons
- Suction only grips smooth surfaces
- Carbide stage is aggressive on good knives
- Small body for long blades
Key specs: 3-stage pocket sharpener (tungsten carbide, ceramic, carbide scissors slot), suction base with switch, straight and serrated knives, 7 x 6 x 7cm, 86g.
How to Choose a Knife Sharpener in NZ
Sharpener type matters most. Pull-through sharpeners are the fastest and easiest option, using fixed slots to repair, restore and polish an edge with almost no skill required. Whetstones give the most control over angle and finish but take practice to use well, while a rolling sharpener with a magnetic holder sits in between, locking in a preset angle without needing a freehand technique.
Sharpening angle affects both sharpness and durability. Most Western kitchen knives are sharpened around 20 degrees per side, while thinner Japanese-style blades usually suit closer to 15 degrees. A steeper angle cuts keener but chips more easily, and a shallower angle lasts longer between sharpens but feels less razor sharp. Sharpeners with 15 and 20 degree presets suit a mixed knife block best.
Grit level decides how aggressive a stone or stage is. Coarse grits under 1000 repair chips and very dull edges, medium grits from 1000 to 3000 handle routine maintenance, and fine grits from 3000 upward polish and refine an edge that is already sharp. A combination whetstone set, such as a 400/1000 stone paired with a 3000/8000 stone, covers both ends in one purchase.
Consumer NZ advises against regular use of electric or pull-through sharpeners, since both remove a little metal on every pass, and recommends against motorised belt or wheel sharpeners unless you are experienced with them. For occasional home use, a pull-through or rolling sharpener used sparingly is fine; for daily professional-style use, a whetstone used correctly removes less metal overall.
Buying a sharpener also has to compete with paying a professional. NZ knife-sharpening services typically charge somewhere from 8 to 15 dollars per knife depending on length and edge type, with some offering courier drop-off for rural customers. A home sharpener pays for itself quickly once you are sharpening more than a couple of knives on any sort of regular basis.
Match the sharpener to what else is in the block. A basic pull-through sharpener will not touch true ceramic-bladed knives, which need a diamond-specific sharpener, and serrated bread knives need a tapered rod worked into the scalloped edge rather than a flat stone. If your kitchen is stocked with mixed steel, ceramic and serrated blades, the 4-in-1 and 4-stage sharpeners in this list cover more ground than a basic 3-stage design.
A sharpener is only one part of a well-equipped kitchen. On the same benchtop, coffee grinders are one of the most common daily-use companions. A good air fryer is another easy next appliance for anyone who cooks often, and both are worth weighing up alongside whichever sharpener makes this list.

Verdict
For most NZ kitchens, the SHARPAL 198H electric sharpener is the easiest all-round buy, sharpening both sides of the edge at once with no technique to learn, as long as it is used when a knife is actually dull rather than every day. Buyers on a tight budget should look at the adjustable Mitsumoto Sakari sharpener or the pocket-size SHARPAL 191H, sharpening enthusiasts who want full control over the edge should choose the four-sided whetstone kit, and anyone who wants a consistent preset angle without the learning curve of a stone will get the most out of the magnetic rolling sharpener. Kitchens with scissors in the mix are well served by either the 4-in-1 knife and scissors sharpener or the LYMI 4-stage kit.
Frequently Asked Questions
What type of knife sharpener should I buy?
It depends on effort versus control. Pull-through sharpeners are the fastest and easiest, whetstones give the most control over angle and finish but take practice, and rolling sharpeners with a magnetic holder sit in between, locking in a preset angle without needing a freehand technique.
What angle should I sharpen my kitchen knife at?
Most Western kitchen knives sharpen best around 20 degrees per side, while thinner Japanese-style blades usually suit 15 degrees. Steeper angles cut keener but chip more easily, shallower angles last longer but feel less sharp. Rolling and guided sharpeners offering both 15 and 20 degree presets suit a mixed knife block.
How often should I sharpen my kitchen knives?
Most home cooks only need a full sharpening every one to two months, or roughly every six months if honing regularly between sharpens. Heavier daily use, such as cutting a lot of meat, can wear an edge down faster and may call for sharpening closer to every four to six weeks.
What’s the difference between honing and sharpening?
Honing realigns a blade’s existing edge without removing metal, and takes seconds with a steel or ceramic rod before each use. Sharpening actually removes metal to create a new edge and is needed far less often. A dull knife that won’t hold an edge after honing needs sharpening, not just honing.
Can a pull-through sharpener damage my knives?
Fixed-angle pull-through sharpeners can round an edge or remove more metal than necessary if used too often, and are not ideal for premium or Japanese knives with thinner factory edges. They suit everyday steel knives well, but a whetstone or angle-guided sharpener is gentler on expensive or delicate blades.
What grit whetstone do I need for kitchen knives?
Coarse grits under 1000 are for repairing chips or very dull edges, medium grits from 1000 to 3000 suit routine maintenance sharpening, and fine grits from 3000 upward polish and refine an already-sharp edge. A dual-sided 1000/6000 stone covers both repair and polish in a single purchase.
How much does professional knife sharpening cost in NZ?
NZ sharpening services typically charge around 8 to 15 dollars per knife, depending on blade length and whether it’s a standard or Japanese edge, with some offering nationwide courier drop-off. Buying a home sharpener pays for itself quickly if you’re sharpening more than a couple of knives regularly.
Are electric or motorised knife sharpeners bad for your knives?
Consumer NZ advises against regular use of electric or pull-through sharpeners, since they remove a little metal every pass, and recommends against motorised belt or wheel sharpeners unless you’re experienced, as it’s easy to remove too much material or damage the edge geometry.
