If previous entries have aroused an interest in Japanese swords, here are three books to consult.
“The Craft of the Japanese Sword” by Leon Kapp, Hiroko Kapp and Yoshindo Yoshihara (1987) is a clearly written and well photographed description of the making of swords from the materials to the final polishing. It is quite detailed and will satisfy the curiosity of most readers.
“The Japanese Sword: A Comprehensive Guide” by Kanzan Sato (1983) is a beautifully illustrated and in depth study of the topic. It is intended for the serious student.
“The Connoisseur’s Book of Japanese Swords” by Kikan Nagayama (1997) is exactly what the title states.
