The term shingunto (kanji: 新軍刀) means "new military sword" in English. It is written しんぐんとう in hiragana. It may also be rendered in English as shinguntō , shinguntou , shin-gunto , shin-guntou , shin-guntō , shin gunto , shin guntō or shin guntou. It's pronounced roughly like "sheen goon toe".
These swords were the gunto that were mass-produced from the mid-1930s through World War II. As a reaction to the Westernized style of kyugunto, the shingunto was made to reproduce the look of tachi, the swords worn by samurai before the development of the katana.
新, shin, means new and is a frequently-used prefix. It is the “shin” in the famous Shinjuku area of Tokyo (新宿, しんじゅく, literally new lodging), and it is in the word for bullet train (shinkansen, 新幹線, しんかんせん, literally “new main rail line”).
軍, gun, means “military” and is used as a suffix in the words for army (rikugun, 陸軍), navy (kaigun, 海軍), and air force (kugun, 空軍). The to kanji, 刀, by itself is “katana”.
