Hi Jesse As Jean says Rust/corrosion requires 3 ingredients Bare metal/moisture/oxygen Take one ingredient out to rectify I feel in this case ... Add regular oil to take bare metal and oxygen out of equation Pics show some depth beyond surface This didnt develop in one month - It was there before and there for a while , not easily as seen ,because would have been small black dot when kept under control with oil Oil now dried out allowing oxygen to react to bare metal to expose coloured corrosion Original likely cause to be opening in hada/grain/minor forging flaw As Jean said - carefull removal of active corrosion with a soft tool that enters the opening until all red/orange rust gone out of the crevace/opening of the flaw using oil in this process to collect any rust scale - any rust stains on blade that can be seen in your pics can score the blade if you just wipe them off across the blade Do daily , with aid of magnifying glass until no coloured corrosion evident "DO NOT USE ANY FORM OF RUST CONVERTER ON ANY AREA OF ANY BLADE AT ANY TIME !!" When no coloured rust stains visible exerting from opening of area and just black spot visible - you are in control of problem , regularly monitor and of cousre - regularly oil As stated - such a minor defect as this could most likely be corrected and made un -noticeable by a traditionally trained polisher , should you wish to do so down the track All the best ! Cheers , AlanK

Wow Dave That gets my attention ! The "GASSAN SCHOOL " may well be regarded as one of the most Famous Schools of All Time , that actually still practice today ! I believe @Bryce is a serious studier of Gassan works ? I don't collect "The Great Sadakazu " blades, however I realise his Family/School will always be regarded as " One Of The Greatest ! " It would be awesome to see an example of Sadakazu putting a gimei out there I collect Kanenori and my research tells me he was given direct Imperial Orders to make copies of blades , however, He signed them himself ? Interesting.... Cheers , AlanK

Hi gb As is generally the case ... Better pics with no fittings ... Tip up /tang down (both sides ) ... Sectional areas from tip to lower tang .. Lower pic shows habaki/collar lòose fitting , but upper pic shows it not in correct place/dropped down ... Try better lighting/pics of boshi/tip as current pics seem to show area worked on at some stage and disappeared hamon ... ? Maybe , just my old eye's 👀 Cheers AlanK 🍺

Like Brian said ... Basically too far gone Pay to shorten..dunno bout that - $ ! Keep as is maybe... and "Then make up your own "classic story " as to how it happened " Be a good yarn while having a beer

Piers beat me to it They have been up front and more or less told you/everyone viewing their description at the lower part of your original post Interpretation of text can be misleading , they make no Guarantees of item being authentic, and have instructed a path to investigate further Kind regards

Sincerely Thanking You For Clarification Brian ! My eyes aren't the best any more ! The short/cut off pic didn't help Thanks Again Respectfully AlanK

Read this post Have I misinterpreted/lost touch with trends/or something ? I was always led to believe Shinsa would never certify a blade by a currently living Smith? ... This always made sense to me ... as , if an attribution was given and a current living Smith stepped in and said " I didn't make that blade " after appraisal Someone's gona end up with egg on their face ? Same again , have I missed something ? Showato /oil temper blades gaining certification as well ..? With Total Respect To All Parties ! AlanK

Exactly... ! Bring on the pics ! I love seeing GASSAN BLADES !! Keep them coming ! I wouldn't be surprised , if there was " A Hall Of Fame " for Swordsmiths - That The Gassan School - Overall would be Ranked Top Level On The Ladder ! " Respectfully , Al

Hi Bryce Fellow Aussie here 🇦🇺... Awesome research you are doing ! .. However , I understand how others are feeling.... Consider me as an outsider looking in .. that's why i will comment ... The "GASSAN SCHOOL " could probably be noted as " The Greatest School of Swordsmiths Ever ! " They still are active now ! - Wish I owned one ! Stand back ... think about all these Signature Discrepancies - You're talking about ......! It almost , looks like " .... The Gassan School " gets away with it and gets granted certificates for other siblings /students signing them - this is where contradiction/authenticity / discrepancy begins ... These guys feel they're getting there investments devalued... because of this ! The Great Sadakazu was Awesome ! As was - Sadakatsu ! FYI : 4th April 1906 Miyamoto Kanenori/Gassan Sadakazu were appointed Teishitsu Gigien Direct Swordsmiths of The Imperial Court - They were the only 2 Swordsmiths to ever be awarded this title My collection is based on ... The works of Miyamoto Kanenori I feel he is ..underrated ??.. However , He Was The Only Swordsmith to be given a " Direct Imperial Court Ranking -Shoshichii #7 " to my knowledge ?? I attach a title of a book written for the Great Kanenori , which may also advance your studies ?

BTW The information is general and has " Nothing " to do with this particular blade ! AlanK

Was going to offer some information towards this thread However , recently all I get on my mobile app through Google is blotched vision on most threads ?? Alan.K

A couple of decades ago plasma television's were all the go , my Mrs wanted to know why I could buy swords , yet the family couldn't have a 5000 - 10000 $ TV, like all our other friends ? I calmly sat her down , held her hands and explained to her that our $900 TV would outlast the plasmas and that the swords would last forever and be a valuable asset for our children As time went by , she realised that I was correct and now we still have the swords and enjoy a $1000 65" flatscreen TV Win/Win situation ! :-) Merry Christmas and a happy new year to everyone !

Hi Bryce In 1918 The Great Sadakazu passed away .... ? He was " One of " the only "2" swordsmiths to ever be awarded " Teishitsu Gigien " Status - Direct Imperial Court Artisan ( April 4 1906 ) I can also see Dirks' reference I know more about Kanenori than Sadakazu Out of respect for such "A High Ranking Title " ... To my knowledge - Kanenori , Always stated , Title/Name /His Age/ on his Mei To our knowledge.... Sadakatsu is the Son(adopted?) of Sadakazu My question is.... in your research , is there any " MEI " you have seen , signed by "Sadakazu " after 1906 without his "Teishitsu Gigien " Title Status appearing on the Mei (that you would consider Sadakatsu signed ??) If so . Shinsa is the only answer Sorry if I missed something here !! , however you have brought up something here that I have heard of several times now and would appreciate clarification ! Cheers AlanK

Thanks for the clarification on that John /Shugyosha ! Hizen not my area , just remembered it as it has been mentioned before , so it , caught my attention , (Reason for my question marks ?? ) Kind regards , AlanK

Generally Anything Hizen ... Tachi mei ??
