Iron Habaki - A deep dive on the original habaki material

[nulldevice]

Hello NMB! 

 

I'm happy to share a new article I've been working on for some time now going deep into the origins of the iron habaki. I realized there is not much written in English on the subject of old iron habaki and yet they seem to be present on many surviving shrine swords and ubu tachi and katana from the Heian through Muromachi periods. Google searches for "iron habaki" or "jigane habaki" yield a few NMB threads and really nothing else on the subject. So hopefully this can be a fresh look into an oft forgotten, yet important piece of hardware that aren't too often encountered in the world of nihonto!

Hi Chandler, 

 

Wonderfully insightful and well-researched article, thank you for taking the the time to research this topic. 

 

I can recommend. 

 

Best,

What an awesome read! Well done on your work for this and I appreciate the pictures and text translations.

Very interesting, I did not know about later iron habaki. Here ofcoarse is an early one.

I was quite pleased when I found the stories of a Bakumatsu revival of the old iron habaki. It makes sense to me because we see also at the same period a resurgence of blades made in the shape of the old grand odachi of the Nanbokucho at the same time. I am on the search for any images of an iron habaki made in hira-awase style where the seam is clearly visible on the side, but so far such an image has eluded me.

You mean these guys? I have not seen later stuff, but the original ones tend to be ugly and they seemed to have very narrow popularity timeline.

I believe they are along those lines yes. I’ve been looking for a Bakumatsu example but they are very very scarce it seems.

Chandler, absolutely fascinating read. It was a subject I thought about with the exact thought that copper and gold seem too soft for battle. 

 

That you mention gold habaki's arrived much later aligned with my previous research into Gotō Yūjō who is today considered the father of Japanese goldsmithing. It all makes sense.

 

Thank you so much for spending the time to do the research and share your knowledge and findings.

 

I will not look at the humble (& rare) iron habaki again in the same way. Veil lifted. Thank you.

Thank you.
I know that Barry @b.hennick has an interest in iron fittings.

Thanks so much @MassiveMoonHeh! I was in part pushed to get this over the finish line after seeing all of the wonderful research you have done recently and provided here. 

 

It seems like the problems with iron habaki were well known for a while but during my research, soft-metal habaki came into play as the defacto material much later than I expected. We are so quick to get new habaki made that I've wondered how often original soft-metal habaki survive with their accompanying swords? It seems that solid gold fittings are often well preserved due to monetary value alone and the designs that go into them but we know these aren't designed for use, and are just for show. Meanwhile the problems that caused iron habaki to go out of vogue, are probably the very thing that has helped them survive all of these centuries later. They're just a lot more hardy, barring rust, than soft metal habaki.
