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.
