1. Toplus Knife Sharpener (Top Pick)

Toplus Knife Sharpener - Professional Kitchen 3 Stage Knife Sharpener for Straight and Main Kitchen Knives, Diamond, Tungsten Steel and Ceramic Rod Helps Repair, Restore and Polish Blades

The Toplus knife sharpener is one of the best you can get in terms of price and ease of use. It has three slots for sharpening: a diamond rod for coarse sharpening, a tungsten steel blade for fine honing, and a ceramic rod for finishing. 

The body of the sharpener is solid and durable, so it can take a beating. One nice feature is the non-slip rubber grip on the bottom of the sharpener so it won’t move when you rest it on a table while sharpening. 

This is suitable for all types of kitchen knives, except serrated blades. You can resurrect a blunt knife fairly quickly or maintain a razor edge on an already sharp knife.  

If you’re looking for a reliable knife sharpener that is quick and easy to use, then this is the one. 

What We Like:

Very effective
Easy to use
Non-slip base

What We Don’t Like:

Not for scissors or serrated blades

2. Chef’s Choice 312 (Best Electric Knife Sharpener)

Chef’sChoice 312 Diamond UltraHone Electric Knife Sharpener for Straight and Serrated Knives Diamond Abrasives Precision Angle Control Made in USA, 2-Stage, White (Discontinued by Manufacturer)

This product from Chef’s Choice is our pick for the best electric knife sharpener in Australia. A typical kitchen knife comes with a 20-degree edge from the factory, but this device puts a 15-degree edge on a knife, making it super sharp. It also puts a triple bevel on the blade, giving it optimal strength and cutting power. 

This is a little expensive for a knife sharpener, but it turns ordinary kitchen knives into razor-sharp instruments that cut with ease. There is a slight learning curve to using this, but once you get the hang of it, it’s easy and fun to use. 

This works with both straight-edge and serrated knives; the diamond abrasives work the blade to a fine edge in stage one and two, then a flexible abrasive strop finishes off the blade to give it a perfect edge. 

If you’re willing to spend the money, and you want the best, then you should definitely check out this sharpener.

What We Like:

Gives a razor-sharp edge
Easy to use
Works on straight-edge and serrated knives

3. AnySharp Knife Sharpener

AnySharp ANYSHARP Knife Sharpener, Blue

The AnySharp knife sharpener is simple to use and takes a lot of the hassle out of sharpening. 

It has a suction cup on the bottom and can be easily attached to any surface by pulling the lever down. Sharpening just requires dragging a knife across the tungsten carbide head. A heavy pull will sharpen up blunt knives and a light pull will put a razor edge on them. 

This is a great tool to keep in the kitchen so you can touch up your knives whenever you do some cooking. It won’t give a knife a super sharp edge, but it does a more than adequate job for home cooking and it’s very convenient. 

Overall, this is a great, inexpensive tool that will keep your knives in good shape.  

What We Like:

Easy to use
Strong suction cup holds it in place

What We Don’t Like:

Doesn’t give a super sharp edge

4. BYETOO Kitchen Knife Sharpener

BYETOO Kitchen Knife Sharpener, Manual 3-Stage Knife Sharpening Tool,With Anti Slip Bas, Geramic Rod, Diamond Rod, Tungsten Steel Blade, Restore and Polish Blades, Safe and Easy to Use, for Straight Blade Kitchen Knives

The Byetoo kitchen knife sharpener is pretty reliable and is a good choice for the price. It has three sharpening heads; a tungsten steel edge for rough grinding, a diamond rod for medium grinding, and a ceramic rod for putting the finishing touch on a blade. 

It does a very good job of sharpening and doesn’t take long for you to notice the difference it makes. The overall unit is pretty solid and the base is non-slip with a rubber lining so it stays in place while you use it. 

This works like most three-stage sharpeners, but it’s a good buy for the price. It’s easy to use, easy to clean, and it can take a beating. 

What We Like:

Easy to use

What We Don’t Like:

Doesn’t work with serrated edges

5. CARVER MARVEL Kitchen Knife Sharpener

CARVER MARVEL Kitchen Knife Sharpener - Professional 3 Stage Kitchen Sharpener for Premium Knives, Sharpens and Polishes Knives in 30 Seconds

Here’s another three-stage sharpener from Carvel Marvel. This one is very fast and easy to use. You just drag a knife through each sharpening head a few times and it’s done. It may take longer for very blunt knives but it will still put a good edge on them in a relatively short time. 

The grip design is quite comfortable to use, and the base has rubber feet to prevent slipping. It has three sharpening heads: tungsten steel, diamond rod, and ceramic. This does a great job, but it’s a little more expensive than other, similar sharpeners. It’s more comfortable to use, but you must decide if that’s worth the extra cost. 

Overall, this is a great sharpener that works fast and feels good in the hand.

What We Like:

Fast sharpening
Easy to use

What We Don’t Like:

Costs more than similar sharpeners

Knife Sharpener Buyers Guide

What types of knives are you using?

Most sharpeners won’t work with serrated edges. Some will work with ceramic blades and some won’t, so always check the packaging. 

For very fine edged knives, like Japanese sushi knives, a standard knife sharpener won’t be suitable. In that case, a very fine whetstone is required, or they can be sharpened by a professional.


Multiple heads

Different sharpening heads remove different amounts of metal from the knife’s edge, unlike honing where metal is reshaped instead of removed. 

A coarse grind removes the most metal and is good for very blunt knives to give them the right shape. Medium grinding puts a sharp edge on the blade, and fine grinding brings the edge to razor sharpness.


Knife sharpeners are more convenient than a sharpening kit because the heads are set at the correct angle to give the knife a 20-degree edge. There is no guessing and very little skill required. Sharpening stones require water and room to work. There is also a lot of skill required.


Knife Sharpener FAQs

Is An Electric or Manual Knife Sharpener Better?

Electric knife sharpeners are significantly more expensive than manual ones, but they give a perfect sharpening every time. They are easy to use as you just press a knife into it and let it do its thing. They work on both straight edge and serrated edge knives.

Manual sharpeners are simple to use but they can be a lot of effort to use if you have a lot of knives that need sharpening. They are not as fast as electric, but they are more than adequate if you only use one or two knives regularly.
