Hi all! Thank you so much for contributing to this topic.
I haven't studied any sorts of martial arts, and i wasn't planning on actually using these pieces, outside of just unsheathing to study the blades itself. Also i plan to display them in a small room i have upstairs where i stashed up all my tea equipment:)
Its a tachi *(nagasa: cutting edge is 76cm) coupled with the wakizashi will become a dai-sho with antique fittings (menuki, fuchi & kashira and the tsuba). The saya and tsuka will be modern made in Japan by traditional craftsman. The saya for the Hisayuki tachi is currently done with the laquer work and waiting for the fittings.
I'll try to show some decent photo's in upcoming posts, i have so much information in my head regarding to these 2 purchases that its super hard to write it all down in a sensible fashion!
Edit: in regard to the first reply, both will be in standard koshirae because otherwise there wouldn't be much of a daisho in the end;) The saya's will have (only 1 is finished at this point in time) ishime lacquer finish (as if beating by stone). Like here:
Only in a darker earthy brown.
Edit: Also a few nice selling points these 2 swords have is that the Tachi by Hisayuki is listed in the Shinshinto Taikan (having references to the top smiths of the shinto period) and the first Nagamichi was listed as a grandmaster of sharp sword making, only (if i'm not mistaken) 13 smiths are taken up in that category of grandmastery.
