3. Kitchen knives are not disposable

Then you might be thinking…

How do I take care of my knife?

I recommend using a whetstone to sharpen your knife.

The basic idea of sharpening your knife using a stone is…

But a sharp knife has a zig-zag edge.

And this is why your knife can cut foods.

4. Sharpening whetstone will elongate the life of your knife for sure

Let’s say you sharpen your knife once every 2 months.

If you do this,

In 10 years, the blade of the knife will be half an inch (1.4cm) shorter,

And the width of the blade will be 1/8 Inch (4mm) smaller.

It is in 10 years!

This tells you you can use your knife for more than 20 years.

As you learned, kitchen knife blades are made to last for years.


There is one problem…

It is the handle of the knife.

Most likely these handles get broken before the blades are worn out.

5. The life of the knife is actually depending on the handle

It is dangerous to use a knife that has a broken handle.

You will get injured if you keep using it.

You should go to a repair shop to fix the handle.

Or, you should buy a new one if the repair fee is not affordable.

Do you want to know how to take care of the handle?

Remember these two things.

Don’t soak your knife in water.

After cooking, wash your knife immediately and dry it out.
