"New product, there is (masu)"

Such a piece of paper was stuck on the “Mitsuha General Store” in the royal capital.

"Sister, what again ..."

Sabine-chan said with a sulky face.

"Huffy, it's a blasting agent for a living country!"

That said, I pointed to tools, simple metal products, and various materials purchased on Earth from the Rephilia trade in the Kingdom of Vanell.

From Vannel Kingdom, tools used in shipbuilding and “manufactured products that are one rank or two ranks higher in this country today,” if you work hard in this country to make degradable imitation products.

And from the earth, "the same thing can not be made immediately, but what should be the goal, and what should show the right direction as much higher height", the basic thing in the earth as the earth.

Specifically, a measure (measurement tool), a screw, a screw, a bolt and a nut, and others, a screwdriver, a wrench, and the like.

There are various theories about the screw, such as the theory that Archimedes invented it on the earth, the theory that Archytas invented it, and the theory that Apollonius of Perga invented it. It has already been invented in this world.

: Yeah, "The invention has been made."

It was a long time ago that the screw was invented on the earth, but it was not long ago that enough strength, precision, and the same standard were produced in large quantities, and it became an industry leader. Absent.

Yes, “strength, precision, mass production”!

And what is needed to make an object is not only the material that becomes the material, but also a tool for making it and a standardized or “standardized” measuring device.

Measure, vernier calipers, various gauges, and various other measuring instruments must be disseminated in a unified standard.

Despite being the same product, it is worth noting that the size does not match and it is impossible to remove parts from other individuals!

Those who make such products jump off from high places without rubber ropes!

…… Banshi-Jump.

That's noisy!

Anyway, unified standard measuring instruments and various screws of exactly the same standard that cannot be made with the technical skills here.

Sell this in small quantities as a free sample at low prices, and then sell it at super high prices.

Then they will try to make something similar, if not the enemy.

Yes, industrial development can't be done in our territory. You have to rely on hundreds of thousands and millions of people's efforts and ingenuity to scatter tips and samples.

The purpose is self-production in this country, and the overall improvement of technology.

... So, I'm going to scatter these things one after another!

In this world where there is no patent system, market monopoly cannot be done anyway. The manufacturing method would be easy for a worker on site to talk with a few gold coins.

Anyway, the first is a screw.

Industry starts with screws and ends with screws.

The gun's tail plug is usually screw type.

In Japan, it is said that Neji was the first person to have arrived at Tanegashima with a matchlock gun.

Why wasn't the screw invented in Japan, even though it was invented a long time ago in other countries?

… Well, speaking of that, there are races that did not invent wheels until quite late, and are there various things?

And for the time being, the head of the screw is unified with a minus.

No, most of them are Phillips screws in Japan now, but Phillips screwdrivers will not get stuck if the holes are clogged or rusted. Or, if the material of the screw is soft, it can be easily licked .... The groove on the head of the screw will be crushed..This means that it cannot be removed again.

Would not be suitable for beginners who use poor metal materials and techniques.

If it is minus, you can turn it with copper coins even in narrow places, and if you pay attention, the probability of licking is lower than plus.

In the first place, there was only minus on the earth at first.

Despite having many disadvantages, there is only one advantage: it can be turned immediately if the driver is properly inserted into the hole. The work time is shortened because there is no need to adjust to the ditch like a minus, so ... It is a big villain who monopolized the market share.

How many times have you crushed (licked) the screw hole and became a miserable situation so far?

In this world, a positive devil will probably appear someday, and it must dominate the world.

But I will continue to have a little resistance until that day ...

"That's why Japan's measuring instruments and screws, and so on. It's a culture shock to the craftsmen of the country, or of this continent!"

"... Is it okay ... Something seems to fail ..."

Sabine-chan looks worried, but the technician jumps on new technology and new toys.

* *

"Ooh oh! What's this!"

Kunz, great delight!

"What a great discount for the first time!

There is every time!

Well, if you're a research enthusiast, Kunz, you'll jump.

"what is this!"

Umumu, a blacksmith making tools, not weapons, is surprised. Like Kunz, I guess it's a purchase.

"It's evil! A skilled technician doesn't need such a dubious thing!"

… Yes, I ’m back.

"... what is this ... what is this ..."

Oh, this is a new reaction.

"I can't do it. I can't make it ..."

… Yes, I dropped my shoulders and returned….

After that, it was roughly one of those three patterns.

And not many people responded like Kunz. It is also limited to woodworking craftsmen, like Kunz.

"That's why I told you ... If I could find such a thing without a proper explanation, I would either reject it or be overwhelmed by the difference of too many levels, and I would decide to do that ..."

Sabine-chan once again said something negative to my plan.

"Huh? But did Kunz and the woodworking craftsmen accept it?"

Yes, the reaction differs from person to person.

You don't have to be everyone, if only people who like you can use it ...

Then, you will soon understand its goodness, and those who are stubborn and those who are old will soon be understood and accepted.

"No, all of us, including Uncle Kunz, were woodworkers. You just buy tools and metal parts and use them.

The job is to use them to process wood and make wood products, so you don't make your own tools and materials for processing? "

"Ah……"

! !

Certainly, Japanese carpenters do not themselves make planes, saws, finger squares, or nails. It is professional craftsmen who make them. In other words, those who refused to accept, those who returned after being depressed ...

Ah.

"It seems like he finally understood .... So, at the moment, there is no one of such craftsmen who recognized the tools that my sister had purchased this time and thought about trying to make my own. I don't think it was ... "

Oh, what a hell!

I saw the stubbornness of the craftsman sweetly ...
