No matter what you like to cook daily, most people use a knife in some form, whether a carving knife, Santoku knife or cheese knife.

Let’s cut to the chase!

How often should you sharpen your knives?

We’re sorry to say it, but there’s no set amount of time when it comes to how regularly you should sharpen your kitchen knives with a knife sharpener. So, unfortunately, you can’t simply put a reminder in your calendar to include it in your regular chores. In saying that, you’ll generally want to sharpen your knives at least once every few weeks. Whether a Japanese kitchen knife, carving knife or chef’s knife, it really comes down to how often you use them and how well you look after them. Professional cooks tend to sharpen their kitchen knives more often or even hire a professional sharpener once every few years (yes, that’s a thing!)

How to know when you need to sharpen your knife

So, if you can’t put a time on how often you should be sharpening your knives, how do you know when to pull out your knife sharpener? Thankfully, there are many signs that will inform you when it’s time for a sharpen. Don’t worry, they’re all really obvious!

It’s smashing food

When we say smashing food, we don’t so much mean your food explodes in all directions when you cut into it with your blunt knife. Instead, we mean that your knife doesn’t slice cleanly, but smashes cells in your food. Many fantastic recipes require clean and sharp cuts, whether for aesthetics, texture and flavour distribution in a dish. Cutting something soft like a ripe tomato is a great test for this - is your slice clean and sharp, or does the skin of the fruit look a little mushed or dented when you cut it? 

It’s slipping off food

Have you ever gone to cut into an onion, only for it to slide down the curve of the vegetable? If you have, chances are your chef’s knife or Santoku knife needs sharpening with a knife sharpener. Whether an onion for a fantastic slow cooker recipe or melon as part of a delightful dessert, a knife sliding can be dangerous and cut your skin. 

It doesn’t pass a sharpness test

There are many different knife sharpness tests. Each of them are great for checking how sharp your knife is before accidentally ruining your food. A common test includes:

Paper test 

Simply hold a sheet of paper up and try to cut through it with your knife. Whether a carving knife or even a steak knife, it should slice through it easily. Otherwise, it needs a sharpen.

If it feels like hard work to use it

Cutting veggies with a chef’s knife or cheese with a cheese knife shouldn’t be hard work. You shouldn’t work up a sweat, and your elbow certainly shouldn’t be in pain. If it feels like you need to apply too much pressure to use your best kitchen knives, they need probably need a sharpen. Or, you’re not using the right knife to start with.
