I'm pretty sure its 昭和未年新春 (spring, year of the sheep) = 1967 Edit: corrected

Yes, 寒山誌（花押）　Kanzan shirusu (it means "written/recorded by Kanzan" with his monogram at the bottom). I don't know if its authentic or not. There are a lot of fakes out there.

To be honest I've never heard that smiths had to submit samples of their work to the bakufu or to the court in order to receive the title. I think they had to make a formal application, or have one made on their behalf by someone of status (the actual daimyo of the fief, for example). But I am not a deep scholar in this area. I have read Markus Sesko's article here, which I think you will find very interesting if you haven't already read it. It provided the basis of what I know. https://markussesko.com/2013/02/19/how-honorary-titles-were-conferred/ Whether this particular sword is one of his best examples or not; I think there are too many variables. The biggest one is condition. It could well have been one of his best examples, but you'd need a deeper inspection and you'd need to compare against his other known works to make that call. And I don't think one can even make a sweeping generalization about swords produced before/after receiving the title. For some smiths it may be true that their best work was toward the end of their productive life. For other smiths they may have become lazy, lost their vitality, lost access to good quality tamahagane, or some may have allowed their apprentices/students to produce under the smith's name, and so there may be some variance in quality. Other smiths may be "average" smiths, yet had the funds to acquire the title, so...too many variables to generalize.

Uwe is correct. Yasuchika saku.

Date on the sword is Kansei 10, August. Bear in mind, in the shintō period the dates inscribed are almost always either August or February (well, strictly speaking its "Eighth Month" and "Second Month" - there is a discrepancy between the traditional Japanese months and those of the Gregorian calendar). These two months are used regardless (almost) of when the sword was actually forged. So best not to take that date too literally. I wouldn't place too much significance on the title, or the privileges it conferred, or the deference paid to the swordsmith upon receiving the title. It's not representative of admission into the nobility. "Lord" or "Governor", "Protector", etc. are just honorific titles, so the smith isn't in any kind of professional limbo until he receives the paperwork. The title just allows him to inscribe his swords with that title, and of course it is an honor for him to do so, but otherwise his life and status doesn't change. Maybe it allows him to increase the prices of his swords slightly. Also the granting of titles was, to some extent, a revenue-generating scheme for the bakufu. So the standards for granting of titles may fluctuate depending on the finances of the bakufu and/or those of the officers in charge of granting titles.

My guess is 安秋作　（Made by Yasuaki). But I can find no such metalworker in the Wakayama index.

Very strange. Illegible to me. The 怍 (saku) is fine, but the character (or characters?) above that are a mystery. An attempt to fake a mei? An addition of some chisel strokes to deliberately obscure the Mei? Unusual.

Hi John, I saw one just like it on Japanese Yahoo for sale. It's described as a commemorative paperweight. It's not uncommon for these to have a loop and cord on them. So I think it started life as a commemorative souvenir for cultured folks.

It's a paper weight - 文鎮 - the kind used when doing calligraphy.

Other side is 潜龍 "Hidden Dragon" 源義制 佩劔 Owned/Worn by MINAMOTO Yoshinori. Hidden Dragon would be the name given to the sword. I think Minamoto Yoshinori was a hatamoto in the Tokugawa Bakufu Government.

One correction 竪丸形 Tatemarugata Nengō is correct. Edit 型→形 (had to correct my own correction)

Hello Kirk, I was just commenting that this sword has been popping up on this board frequently. I meant no insult to the sword. I haven't looked closely at the sword, so I have no strong feeling about it, but yes I presume it is an arsenal blade.

This sword has been posted to NMB at least 3 times in the past few months.

This sword keeps coming back to NMB like a bad penny.

I think it is meant to be the 4-character idiom 以守為攻 (守りを以て、攻めと為す), which in colloquial English would be "the best offense is a good defense". It means secure your victory by shoring up your defense. But it looks like they've spelled it as 以守以攻, with a slight variance in the third character.
