Hi,
Why i say that this blade is tired? it seems to my eyes that it was some suspect zone near the yokote and on the first pic in the middle of the blade like loose grain, also the shinogi-ji has ware.
I should like a pic of the whole blade and one of the nakago without the habaki.
You ask for some judgement, i give mine and it's only mine.
Hi,
Darcy says:
That's right and the nakagojiri of Osafune Kanemitsu is kurijiri haru (thick)
not ha-hagari kurijiri like this one.
And i should be surprised to find an Osafune Kanemitsu without any papers.
hi,
Nie and sunagashi appear in many schools, sugata and line of the hamon are very important (we have no help with the nakago). The exemples showed by Jean (Salut le titi :D ) have a hamon wich is not in accordance with your blade one.
Shinza will be the last judge :D
Hi,
It's not a book, it's an article which was written in 1981 by Harvey Stearn in the Bushido journal.
You can also look at here especially the paragraph "Japanese sword from ancient times". I think that is instructive and show the necessity of the smith's skill.
Hi,
I've an article talking about tsukurikomi. this article contains some pictures wich shows the disposition of the hard steel and the soft one.
These pictures confirm that Ted says.
Hi,
I think there is a misunderstanding, i use alcohol only in subsitution of the uchiko powder (old oil tends to get hard) after that and when my blade is absolutely dry i apply a thin covering of new choji oil until i need to clean my blade again.
In France, where i live, rubbing alcohol contains 90% alcohol, i use it without any problems (it's promptly dry and no scratchy). Perhaps rubbing alcohol is not so pure in Canada or States.
