Now, Japan is an unprecedented Japanese sword boom. Wakao has published many articles related to swords such as " Sengoku era in which swords were used in actual battles! Introducing legends of warlords and great swords ", but this time a basic commentary is provided for beginners to learn about swords. We will deliver.
Four questions about Japanese swords and swords
First of all, I asked Iroha of the Japanese sword to Toshihiko Suekane, a researcher at Kyoto National Museum and a specialist in metalworking!
Q1. What is the condition of the famous sword?
A. There is an excellent sword for each viewer. A beautiful sword from the beautiful. A great sword because there is an ugly episode. A good sword because it was possessed by a warring celebrity. Everything is "yes". Of course, there are standards such as “Iron is well-kneaded and processed well (a good skill)”, but the attraction is not unique. It is the goodness of the Japanese sword that each seer can find the ideal sword, and at the same time the attraction of Japanese art.
Q2. Does the Japanese sword change with the times?
A. Yes, not. The Japanese sword was made in the form that suits the way of the era. The beginning is the iron straight sword. Its appearance was in the Kofun period. After that, the senior warriors of the Heian period who fought on the horse top are long and warped big swords. In the Warring States period when we fought on foot, it seems to be a short batter. In the Momoyama period, a sculp-e-style picture depicts the figure of a sculptor with a bat. However, depending on the place of production and the creator, the difference is born, and there is also a sword whose shape and cutting edge (pattern of the blade. The features of the creator and the times appear) have been changed by regrinding. When he sharpened his sword, he drew an edge that he thought was beautiful with his scratching technique. I did make a makeup. What we are looking at is a form that involves a variety of factors.
Q3. Japanese swords, where are real names and where are nicknames?
A. For example, "Samurai" is the real name, "Yasuna" is inscribed, and "Doji Kiriyasuna" is a well-known name. The official names of all swords are "Sword", "Sword" and "Dagger". The inscription entered after that is what the author himself engraved, and it is written that the author name and owner name, production area and age, etc. There is also an unbeknownst sword. "Favorites OO" and "No OO" are nicknames. It depends on the sword who started calling when, but mainly "owner name" "feature and state of the sword" "legends and episodes" is the origin. The “Doko Kiriyasuna” was named after the anecdote where Yorimitsu cut off the demon, Shuten Doji, who lives in Mt. Oe of Tamba country (Tanbanuni).

Q4. What does Japanese sword mean in a word?
A. Mental support of samurai. It is "the ace of restraint" in baseball. Actually, Japanese swords are not the main weapon. Bows and arrows are the main weapons of senior warriors who fought on horses during the Heian period. I have always equipped with a sword and a low end sword (Koshigata), but I use the side arm only at the moment of emergency. It can be said that the Japanese sword was not only a weapon but also a mental support. A sword is drawn on the portrait of a samurai who was once considered to be Mr. Ashikaga, but the main weapon of this era was also bow and arrow. It will not change even if the times go down and the main weapons become firearms and guns. In other words, the Japanese sword is an eternal relief pitcher in baseball. It was an ace of curbs.

I would like to say it out! Industry term of Japanese sword
"A lot of good luck"
It is a powerful sense of words, but it is a word that compliments the elegant silhouette of the sword blade. When the width of the tip is very narrow compared to the width of the waist part near the handle, it is said to be “strong in strength” or “a shape with good strength”. There are many styles for old swords.
"I'm getting angry"
I write "錵" and "沸" and read "Nie". Coarse brilliance of grain that floats at the border of blade and ground iron. If you can see the glow like a star in the night sky in Kumon, you'll see, "I'm buzzing well," "I can see a strong boil on my skin." It is a compliment.
"Skin bites"
It is a word to say against the skin of the sword. Iron is beaten well, and the state that the skin looks fine is referred to as "the skin is clogged", and it is expressed as "the skin is clogged well." If you can see a fine grain pattern, you can say, "The skin is clogged well".
