Traditionally made blade, signed Tadatsugu.
For me, hard to pin down the two character mei to any particular Tadatsugu, not much info, although I think the mei is genuine, doubt Tadatsugu is a target for a gimei anyway. Neatly signed, maybe an obscure smith, I cant say for sure. Mid to late Edo I guess.
The blade caught my eye, unusual nakago shape, Maru type mune, Sujikai Yasurime just about visible to the naked eye. Nice patina to the nakago, although I doubt my photography will help.
Mokume hada (quite tight) with Notare hamon visible. 17.5" nagasa, not had time do all measurements yet.
The koshirae fittings are ok for the price, Shakudo Kashira with an horse engraved, Shakudo plain fuchi.
The tsuba is solid copper with a Shakudo finish, feels hefty in hand.
Only one menuki, appears to be iron, clueless as to what it may be, possibly a shell.
The Tsuka ito is not the best ive seen, but adequate, not too worn either.
The saya has seen better days, split at the opening and loss of lacquer here and there. I assume this could be sorted out if the new buyer wished to do so, I have the details of a craftsman in the UK they could ask, tsuka too.
The blade sadly comes with a few dinks and scratches, looks like some kids have had it at one time or another, possibly a Zatoichi type character kicked off in an Izakaya lol, joking aside, one or two where likely made by another blade, saw these through the eye glass earlier, fun to speculate.
Anyways, £495 ono, buyer covers any fees, donation to NMB if sold here.
Will get a shipping price for anyone interested, PM me at email@example.com if interested and I will give you more pics and details.
Will add a few pics soon
