The best knife sharpeners in Australia

A knife sharpener grinds the knife's blade, creating a new, sharper edge. Knife sharpening is important because a sharpened knife does a better job at cutting and slicing food and allows for faster and safer meal prep.

There are different types of knife sharpeners. Stone sharpeners are the simplest, while more complex options include electric sharpeners, multi-feature sharpening stones and ceramic models.

To find the best one for your kitchen needs, consider whether you want a rod, stone, electric, manual or ceramic sharpener. A multi-feature option is best for a wide range of tools and blades. A rod or stone is ideal if budget is an issue.

Our team looked into hundreds of knife sharpeners listed on Amazon and chose the best models to help you pick the right product. We chose options based on customer reviews and ratings. We also considered each knife sharpener's key product features, including price, ease of use and other functions.

What is a knife sharpener?

A knife sharpener helps sharpen and hone the edges of knives and other blades.

What can a knife sharpener do?

It can breathe new life to dull knives and other blades. It also helps polish the edges of knives, making them easier to use for cutting your favourite ingredients.

Types of knife sharpeners

There are different types of knife sharpeners for a wide range of use:

  1. Sharpening stone.This tool is one of the most popular methods used to sharpen a knife. It is typically made of aluminium oxide or silicon carbide mounted on a non-slip sheet for stability. This has fine to coarse grits to accommodate different knives and blades.
  2. Sharpening rod.This type of sharpener doesn't really sharpen knives, but it hones and realigns the tool's edges to maintain sharpness. It is typically made of steel, diamond-coated metal or silicon carbide.
  3. Ceramic sharpener.A ceramic sharpener is extremely hard-wearing and can be used dry or with water or cutting fluid.
  4. Electric sharpener.Using a 2- or 3-stage sharpening system, this type of sharpener is the most convenient. It is motor-powered and has guides, allowing you to get the perfect angle for sharpening knives.
  5. Manual sharpener.This also has multiple blades and a 2- or 3-stage sharpening system, just like its electric counterpart. However, it needs more elbow grease to sharpen knives. Most models have an ergonomic handle to make the process easier.

How to compare knife sharpeners

Consider the following factors when picking a knife sharpener:

Purpose

Consider where you want to use the tool for. If you want to hone your knives, go for a sharpening rod. For convenience, electric models with a 3-stage system are your best bet. If you want a large sharpening surface, stones are ideal.

Material

Choose whether you want a sharpener with ceramic blades, diamond-coated blades or a steel rod. Diamond-coated tools are great for honing and polishing, while ceramic blades are durable and can both sharpen and polish. Steel options are great for honing.

Grit

Knife sharpeners come with different levels of grit. Options with a coarse grit are suitable for restoring knives with nicks and chips. Fine grit is for honing while models with medium grit are used for sharpening dull blades.

Versatility

If you have a wide range of knives and blades at home, consider getting a multi-purpose sharpener that can restore different kinds of blades.

Convenience

If you don't mind spending 3–5 minutes sharpening a knife, a sharpening stone or rod is ideal and more affordable. If you prefer something more convenient and quick, electric or manual sharpeners with multiple blades are perfect.

How to keep your knives sharp

Check out these tips to keep your knives at their best:

  1. Sharpen your knives regularly to keep them from getting dull. This will also help smooth out chipped edges.
  2. Hone your knife to realign its edges. It is recommended to do this after every 2–4 uses.
  3. While some knives are dishwasher-safe, the heat and water from the appliance may damage the edges. Wash your knives by hand instead. It might be more time-consuming, but it's gentler than a dishwasher.
  4. Store your knives in a knife block. Storing your knives in a drawer can dull their edges because they are rubbing with other utensils. Using a knife block can maintain their sharpness and minimise nicks and chips.
  5. Use a wooden or plastic cutting board to keep your knives from being damaged. Wooden and plastic cutting boards are softer and easy to wash.
