On my twelfth birthday, my grandfather gifted me a samurai sword that he had long owned and that I had long coveted. He himself had received as a gift from someone who had picked it up while visiting Japan. Up to this year, I had assumed it was a World War II era blade, however, looking at such swords, my own did not seem to fit, leading me to the assumption that it might be much older than previously thought. The sword and saya are in rough condition. The mekugi has been missing these many years, leaving me to wonder why someone would ever drill a whole in the handle--you can see how little I know about samurai swords, but I am learning quickly. It has what appears to be a dragon menuki on both sides. Alas, I could not remove the tsuba in a manner I considered safe to maintaining the integrity of all pieces inherent thereto. I can say though, that it features the Tosa mon of the Yamauchi clan, twice on the pommel and once on the tsuba. I have taken pictures for consideration. And, as per guidelines, I would like to say up front that I am not interested in financial gain by selling this sword. It is very important to me, and something I would like to know more about. Final details: The sword is just over 30" with the blade measuring 22". The saya has a place for a small knife, but that had been removed before my grandfather received the sword many, many years ago. Having owned it now for 23 years myself, I feel a deep guilt that I did not seek out information sooner. Any and all opinions are welcome. Thank you in advance!
