What is Orikaeshi Mei in Japanese Katana terminology?

"""Orikaeshi Mei"" (折返し銘) refers to a method used to preserve the inscription (Mei) on a Japanese sword during the process of shortening or polishing (Suriage). In this method, the tang (Nakago) of the sword, which contains the inscription, is bent backwards and forge-welded to the sword. This allows the inscription to be preserved even after the sword has been shortened or polished.

This practice is not only important for preserving the historical and cultural information contained in the inscription, but it also adds to the aesthetic appeal of the sword. The process of bending and forge-welding the tang requires a high level of skill and craftsmanship, making swords with an ""Orikaeshi Mei"" highly valued by collectors and enthusiasts."
