The reason why you shouldn’t use dull knives is,

It can cause serious injury since dull knives need more strength to cut food than sharp knives.

In addition to that,

The food won’t taste as good because the cut is not clean or sharp.

It means many cells around the cut are crushed and that causes some taste of the food to be lost.

Lastly, the cut doesn’t look beautiful.

This affects the presentation of your food.

1. Well, but my dull knife still does the job..

I know what you are thinking.

Probably you haven’t used a really sharp knife for a long time so you forgot how it felt when you used it.


There are so many benefits of keeping your knife sharp.

2. A sharp knife makes your food taste better

When you use a dull knife, it crushes soft foods like tomatoes and sashimi.

Crushing and not cutting the food can cause a lot of bad influence to your food.

Umami leaks from the food.

And the texture of the food will be ruined.

Your tongue is a very sensitive organ.

So the sharpness of your knife can make very big differences.

3. A sharp knife improves your cooking skills

Can you believe this?

Keep reading and you will find out…

1. A sharp knife gives you better control

You can relax while you are cutting food since you don’t need extra pushing.

And this is the correct way of cutting food when using a kitchen knife.

You will be more confident and less tired of cooking.

2. You can use the weight of the knife to cut


You can cut food just by putting the knife on the food.

That is the feeling you can get while you are using a sharp and keen knife.

Because a sharp knife cuts food by its weight.

It makes it easier to do slicing and dicing vegetables.

A kitchen knife is not made to be used like an axe.

You don’t need strength to cut food.

You need to have good posture.

And you need to be relaxed.

If you use a dull knife, you will feel resistance when cutting the food all the time.


When you use a sharp knife, you feel it differently.

So you can tell the condition of the food.

Like knowing the carrot has more water than a regular one, or if this carrot is a little old etc..

Or you can tell the freshness of the fish and the amount of fat. 

Then you need to adjust the condiments or cooking time.

You can tell a lot of information just from touching the food with your sharp knife.

It sounds like a pro. Doesn’t it?

A kitchen knife is your sensor.

Dull knife needs extra pushing to cut foods.

That means when the knife slips, you can easily get hurt.

That means you will have to do all the activities by one hand.

You will regret that you didn’t sharpen it.

There is no benefit of a dull knife.

Except if you want to be an expert at buttoning your shirt with one hand like me before. (It happened to me!)

5. Why does your knife get dull?

A knife gets dull when it hits the cutting board.

It happens little by little.

Have you used a dull kitchen knife?

I have.

I used the knife in my friend’s kitchen long ago.

I was cutting carrots.

The knife was dull.

And because of that I put too much pressure onto the blade.

The knife slipped on the carrot…

I knew something went wrong.

And a moment later, I felt a pain, then I saw blood coming out.

My friends were worried about the injury and said,

“Are you okay?”

But it was just an annoying noise.

Because I was very angry with myself.

The wound was cured in 10 days.


Everytime I go to that friend’s house, I feel a little bit of fear and regret.

This memory tells me that using a good knife is critical and less dangerous.
