What is Keicho Shinto in Japanese Katana terminology?

"Keicho Shinto" (慶長新刀) refers to the new swords made during and after the Keicho era, specifically those made from the Keicho to the Genna period. These swords are distinguished by their relatively robust characteristics.

The Keicho era (1596-1615) was a time of significant change in Japan, with the end of the Sengoku period and the establishment of the Edo shogunate. This period also saw the transition from the old style of sword making, known as ""Koto"" (古刀), to the new style, known as ""Shinto"" (新刀).

The swords made during this period, known as ""Keicho Shinto"", are characterized by their robustness. This robustness is often attributed to the demands of the time, as these swords were made for use in battle.

The transition from ""Koto"" to ""Shinto"" also brought about changes in the aesthetics and techniques of sword making. While ""Keicho Shinto"" swords retained some of the characteristics of ""Koto"", they also incorporated new elements that reflected the changing times.

Overall, ""Keicho Shinto"" represents a significant period in the history of Japanese sword making, marking the transition from the old to the new and reflecting the changes in society and warfare during this time."
