Hello, I came across Koto Katana blade with bo hi on both sides. Lenght is 70 cm and sori is 2 cm. Bo hi goes trough nakago with diferent lenght_ it is extended in one side. What kind of flow can be hide this way or there is some other explanations?

Thank you for help,

Bojan S.

Hello ,

Is this also tipical process for o-suriage blades. This one doesn't have mei, probably original mekugi and mei was cut off completly? Why would someone preserve one side of nakago? I add some pictures of the blade.

Thank you and best regards.

Yes, it looks like the original mekugiana has been removed. In the process of suriage, they would probably have tried to preserve anything of the original nakago that they could (even if it's just some yasurime or patina), as this gives a small insight into the swords age and origins...

 

It's a nice sword... What do you know about it?

Hello,

I add some more closeups. I only got old Torokusho copy of the sword (which I posted under translate help topic..) from antique seller..It has very nice skin and from my opinion also good polish. It is also very masive and heavy, it should be a monster before o-suriage....possibly Tachi (original lenght of bohi preserved in tachi mei side?)

I'm pretty sure the hamon would be classified as notare midare, judging from the pics. In the last pic you posted, the boshi is midare - a continuation of the hamon. This points to a koto sword. It's a very nice sword in good polish. Congrats!

 

Edit: Torokusho is just a legal registration of the sword in Japan. It won't have any useful information such as hamon type, hada type, school/attribution. For those details, you would have to research on your own, and if you are so inclined, send the sword to shinsa afterward to see if your research is hot/warm/cold.

JIgane is quite nice. Almost too nice for your typical koto blade....If I didn't know better I would be tempted to think it is a modern blade.

It reminds me of my Enomoto Tatsuyoshi I purchased from you in 2003/4, Chris.

I have reservations like Chris. The shape is more saki sori than is usually seen on osuriage tachi (but not completely impossible) and it looks to be in immaculate condition, which begs the question "is this sword really what it appears to be at first glance, or is it a newer sword doctored to look like and old osuriage tachi? " I can't tell for sure...

 

It would be interesting to hear what some others think... maybe we can learn something...

Kunitaro san has the correct explanation I think- this sword is modern made to match the older torokusho. I posted this on the other thread before seeing this one...sorry.

I understand tricks for money of some antique dealers and sword makers, but blade is still very well made and it is in perfect polish. Someone must be doctor swordsmith for Koto blades, which than sell them for the price of only polishing... I could understand someone had time and high goal to made and probably sell this sword for big money with not only to look like Koto, but also put lot of efforts on details....so to look and be priced like higher level Koto blade?...in this case swordsman probably didn't earn much...

Hello again,

I learn something from this mistake. I still want to ask what characteristics on the blade will in this case speak to old and which to new made blade. How is possible to recognize old work from new, which looks like old like in this blade...

Thank you very much,

Bojan S.

Sometimes it can be almost impossible to tell from pictures. It can even be difficult with the sword in hand...

 

You can look for how much the sword has been polished - look for certain styles of sugata, hada (in ji and shinogiji), hamon, boshi, etc. - look for signs of use that might accumulate over the years...

 

Things like that...

 

Experience and study make it easier over time...

 

The picture of mune doesn't look like the sword has seen much polishing... at least since suriage...

 

I don't know for sure if it is old or new, but it looks well made either way...

This thread is quite old. Please consider starting a new thread rather than reviving this one, unless your post is really relevant and adds to the topic..
