Hi, I'm a beginner student in Nihonto. Would appreciate if you could share your experience on this one. I was told it had been a family sword. The kanji reads Horikawa Kunihiro 堀川国廣 on one side and on the other side Keichō 08 慶長八年 at Ashikaga Gakkō school 足利学校. It's a pretty big blade and feels quite heavy in hand. I wonder what you guys think, is it gimei? Is it even worth to consider a shinsa? Anyway I have learned some interesting Japanese history by doing some reading on this. Many thanks! Regards, Mo
