You have made some progress on the road of mastery of the sword and in need of a new Iaito, here you will find the Iaito that are best for intermediate practitioners. Minosaka are a famous Iaito maker from Gifu prefecture, their swords are popular among beginners, but are often also used by intermediate practitioners who don't need any customization on their Iaito.
The Tozando Byakko series and Suzaku series both offer great quality and designs in addition to some minor customization for the intermediate practitioner, with the Byakko series offering extra heavy and extra light blades for practitioners who needs lighter blades due to injury or extra heavy blades for taller people who need longer blades. The Suzaku series are made in Kyoto and uses a new blade made with GT metal which have a balance, look and weight closer to that of a Shinken blade, and designs inspired by Kyoto, the home of Tozando.
