2014-01-26 So, I tried to buy "knife sharpener" at the nearby DIY shop. It cost about 1000 yen. [長年日記]

Nowadays, I have had many chances of household affairs in my country house.

Simply, I became interested in kitchen utensil, so I purchased new pans and disposed of pots.

About kitchen knives, the grip has been decayed and the blade has a nicked edge.

I wonder if I disposed of the knife thought it works.

"Annoying to sharpen this by grind rock"

So, I tried to buy "knife sharpener" at the nearby DIY shop. It cost about 1000 yen.

In short, it looked like a metal abrasive that sharpens a knife.

We can see a scene in TV programs that a chef in an overseas restaurant robs two knives blades each other. It looks like that one knife grinds the other knife.

-----

This "knife sharpener" is awful.

Blade of knife is grinned like Tofu easily.

It takes only 15 seconds to complete it.

I grinned just twice both side blades, the knife cut well frighteningly.

I have never been moved since I had used a "peeler" for the first time.

-----

However, I am a company employee and a kept inventor, and my missions are to think over new computer and network system,

Whenever I watch like the above "knife sharpener" and "peeler" that make us happier absolutely,

I feel flaming jealousy and envy, and heartful maximum praise to the inventors.
