89 …とあるマサルの日常その２

"What the hell is this? It doesn't look like what you said it was.

That day, the smiths were summoned by Masaru.

I told them to use this knife as a sample and to make three identical knives.

In front of Masaru was a sample knife, and in front of the eight smiths were three knives that they had been told to make.

I'm making them because... It's not exactly the same design as the sample, but it's about the same size, and its purpose is to be carried by hunters and adventurers for multipurpose use... right?

Didn't you say it was intended to be sold?

So ......... what was wrong with that? What went wrong?

Even though many of them are young, they are still craftsmen. They don't enjoy being criticized for what they make.

Of course, it's fine if this sample is different from the one you've made. But the problem is that the three you made are not the same. I told you, didn't I? I asked you to make the same knife. Wait!

Wait a minute! You're making them the same!

Masaru's words deepened their doubts, and the craftsmen expressed their dissatisfaction.

Then let's be more clear. I'm saying there is a difference between "made the same" and "same". Your knives vary in thickness, length, precision of the polished surface, and many other ways. What's most unacceptable is why there are hammer marks on the blade. Are you kidding me?

The last one is completely pissed off...but even if it's said to be disjointed, to the craftsmen, all three knives they made look the same.

I'm sure you'll be able to see that the hammer is still there, but not all of them. .... I don't know.

"Now, I want anyone to lay out their knives on this surface plate over here. I know there are hammer marks.

A surface plate is a horizontal platform that serves as a reference plane for measurement and inspection, and Masaru spent more than 30 hours polishing this masterpiece. It is a work of art that Masaru spent more than 30 hours polishing. Incidentally, no skills were used at all.

A scale is placed on top of the knives. This scale is also a common one, only about 15cm long, but it was made by Masaru, and although it is slightly different from the global standard, the scale is not out of scale by 1/100mm or anything. It was made by Masaru and handed out to all the craftsmen so that they could learn the standard of making things.

Look, you see the gap between the scale and the knife? If it's made to the same thickness, there won't be a gap between this scale and the blade. It's a good idea.

"Is it possible that the ......... scale is different?

......... Are you serious? I'm sure you'll be able to figure it out. Now!

Masaru is not a craftsman by any means. He is not a craftsman by any means, but his consciousness has been gradually shifting away from that of the average person since he began studying engineering mechanics in high school, and he is accustomed to precision work due to his experience at a steel factory where he worked for three years before working at a home improvement store, and he is a little too detailed when it comes to work.

I would like to add to Masaru's statement that for the average person, 1cm or 1mm is a small error that is not worth worrying about, but for a person who does hand finishing or machining, a 1mm error is a huge error. As a matter of fact, there are many people in Japanese factories who work in such a way that an error of 1/50th of a millimeter can be detected just by stroking their fingers or looking at the work with their eyes. In the opinion of such people, errors that can be seen with a quick glance are unpleasant. This is the reason why Japan is said to be a fine and sensitive country. .

After that, they talked about how inaccurate their knives were for 30 minutes: ....

"...I feel like I'm being told something great. I feel like I can do it.

"...I don't think I can do it .... I don't think I can do it.

"No, it's impossible... because 1mm is just this one scale, right? I don't think I can do it. .... "No, that's impossible.

"No, it's impossible... because 1mm is this one scale, and 1/10th of that is ." The word "impossible" keeps increasing, and frustration becomes dismay, and dismay becomes resignation.

"Huh? Impossible? Is this still impossible?

Masaru took out nine pairs of knives, exactly the same as the ones he had given as a sample.

"There are nine pairs here. There are ten of them, and as I said before, they're all made with an error of less than 1/10 of a millimeter. If you don't believe me, you can check them later. In case you're wondering, I had three years of schooling and three years of work experience in manufacturing, but I've never done any serious forging, have I?

They all look at me in disbelief, but it's true. I've never made knives, even though I've been interested in it, and I've never even seen forging, even though I've heard of it.

I've never even seen a forging forge, let alone heard of one." "Don't you think it's a matter of pride for a craftsman to offer a product at the same price but not with the same precision? If the weapon malfunctions due to a lack of skill on your part, the lives of those who use it are at stake. Do you really think that's acceptable?

The craftsmen were silent... Yes, impossible or unreasonable is not acceptable.

It's not like we thought we'd be able to do that much from the start, so we're on schedule. What?

"What?

"From now on, you will have three years to be able to do the same thing as this. What?

Three years? Isn't that too short? .... No.

No, no, you are professionals, right? It's not that you can or can't do it. It's not that you can't or won't do it, it's just that if you can't, you won't be able to make a living. Good luck with that. Good luck.

The forgers realized that there was no escape from Masaru's smiling face.
