Whetstone VS Belt Sharpening - Melbourne, VIC

Updated: Jul 30, 2020

With a quick google search you'll soon find that there are many different ways to sharpen your knives and that each method has its own tribe of loyal clientele.

Two of the most popular methods used to sharpen knives are using a Whetstone or an Electric Belt Grinder. This quick read will explain the pro's and con's of both of these methods to help you understand the sharpening processes.

Whetstones: this type of sharpening uses multiple Whetstone blocks which are laid out flat on your bench. By gliding the knife along the Whetstone repeatedly, the blade will become smooth and sharp.


  • Whetstone sharpening is a less expensive option with a quality set of stones setting you back less than $100.

  • Many block sets can be purchased with angle guides allowing you to nail that perfect angle every time.


  • Whetstone sharpening can be very time consuming. Even an experienced sharpener will take upwards of 20mins to get a single knife up to scratch.

  • This method will take a lot of practice to perfect. Finding the required angle and gliding your knives over the block correctly are art forms in themselves.

Belt-Grinders: this method uses an electric belt grinder which spins under the knife smoothing out any bumps in the steel and sharpening the blade.


  • Belt grinders are extremely time efficient with the ability to cut a 20 minute Whetstone job down to just a few quick minutes on the grinder.

  • Flexible belt sharpening leaves your knives with a convex (rounded) edge which produces a more durable and chip resistant blade.

  • Some belt grinder models even have the ability to sharpen a range of blades including your scissors and gardening tools. If you happen to have some neglected tools laying around in the shed, head over to our Garden Tools service to see if we can help!


  • If you don't know what you're doing you can unintentionally take a lot of steel off quick! Make sure to have a few old knives nearby that you're willing to sacrifice in order to perfect you’re technique before attempting with your good knives.

  • An electric belt grinder set-up will come with a much larger bill. These set ups begin at around $200 for the basic models and can range up to $400+ for a commercial grinder.

So there you have it. Make sure to experiment with a few different methods before making up your mind, and remember, the only correct way to sharpen your knives is to do whatever works for you.
