Japanese sword terminology
Want to learn more about traditional Japanese swords? You should first become familiar with the following terms related to them.
When buying traditional Japanese swords, you may come across the word "Shaku". Shaku is essentially a unit of measurement about one foot (11.93 inches). However, it is worth noting that before 1891, Shaku was slightly longer at 13.96 inches.
Another unit of measurement used to describe the length of traditional Japanese swords and their blades is the sun. The sun is a smaller unit of measurement, equal to 1/10 of a foot. Therefore, it is not uncommon to find swords measured by feet and the sun.
Many Japanese swords have a guard called tsuba to prevent the user's hand from sliding on the blade and causing injury.
The kissaki is the point of the blade. In contrast to the medieval swords, the shape of the blade tip is different. While European swords usually form their point in the centre, the kissaki lies on the edge of the blade.
The kissaski plays a key role in the enormous cutting abilities of a katana. It is designed to improve the lethality of the blade, by adding the possibility for thrusting attacks. Otherwise, the blade could only be used for cutting, which severely reduces the options the wielder has.
ha is just the tip of a Japanese sword.
The Yokote Line, also known as the transition line, is the line that separates the blade from the tip of the blade.
hamachi is a gap in the traditional Japanese sword blade. It is designed to separate the blade from the tang.
Although not technically a part or part of Japanese swords, belt is still a key term associated with traditional Asian swords. It is a lightweight belt worn by men and women. It is reported that from 1600 to 1867, Japanese samurai carried their swords through their belts.
Chigusa is almost exclusively produced in Harmia and is a type of steel characterized by a carbon content of 0.7% to 0.8%.
These are the patterns, shapes and geometric patterns that appear on the surface of the Japanese sword. Hataraki is made by polishing.
Tamahagane steel is a special type of steel made of iron sand. It usually contains about 1% to 1.5% carbon and is synonymous with high-quality traditional Japanese swords. However, in addition to swords, Tamahagane Steel is also used to produce knives and tools.
When the blade is tempered again, it is called denaori.
These are just some common terms related to traditional Japanese swords.
