Thanks, I've seen these Nihonto that Aoi markets as swords for Iai. For now my purpose and goal is to study and learn, so I'm not quite ready for a purchase. To further complicate matters, although unsigned it is attributed to the Edo era and I'm inclined to agree with others that swords of this age may be more appropriately enjoyed and preserved for historical value for any number of reasons, safety concerns not withstanding. When I originally posed the question about using a traditionally made sword for Iai practice, Gendaito was specifically mentioned because it seemed like the most appropriate in terms of scarcity, historical value, cost, etc., for a traditionally made shinken.
I'm intrigued by the idea that Jamie put forward and others have implied- that Gendaito shouldn't be considered appropriate for Iai, and that a Shinsakuto should be purchased. Practically, a modern Shinsakuto is out of my reach so I cannot consider such an option. But isn't a Shinsakuto itself a Gendaito (and here I mean any traditionally made sword crafted after Shinshinto)? If all traditionally made swords are going to one day become old and worthy of preservation as art, then surely this notion would apply to the newly made Shinsakuto as well? At this point, is the craft of Nihonto transformed into something else, an object de art wholly divorced from tradition? I don't know, but these are obvious lines of inquiry for a martial practitioner. To all I say thank you for your opinions and advice and beg leniency if I'm broaching the bounds of propriety here, but I'm genuinely interested to know what the arc of opinions on such matters are among collectors and scholars.
Regards,
JP
