One of my Japanese swords is about 700-800 years old (Koto era). It is is still in good shape and is VERY sharp. Japanese  swords from about 1600-1800 are considered "New Swords" (Shinto era), etc.

Steel will outlive you by many lifetimes with proper maintenance.   :)

All excellent good news, I want my future kids to inherit my tools and knives. Hopefully at least one of them will be interested in something that include knives and tools, bushcraft, fishing, hunting or whatever  :)

Here are a couple. The lower wakizashi is the oldest and has a 21" cutting edge, signed Kanemichi. The upper tachi/katana is probably about 400-500 years old and has a 28" cutting edge. The mounts for both are only about 100-150 years old.

For the modders out there, at some time in the past both were shortened a few inches at the handle end. Probably shortened to match the style/need/preference of the time.



This is an 8" cutting edge aikuchi, signed Kanemoto, from about 1500.



Here you can see the steel surface with the laminations as well as the temper line.

Great pictures.  As we can see steel can last a very long time.  As far as rust on LMs.  I have coated mine lightly with oil prior to storage.  Initially I didn't do a thing but figured it wouldn't hurt.  I've also coated my carbon blades that dont see every day usage with Frog Lube.  I've had no rusting issues at all.

Awesome swords...  :drool:

I heard a theory for why we consider old katanas to be so good...
Awl the bad ones were broken hundreds of years ago, and only the luckiest from the best of the best made it to today.  :D
Hooked, like everyone else. ;)

All hail the hook!

Same logic as for old buildings then :D

In the middle ages they did have quality control that was more commited and personal though. The master mason was often made to stand in the middle of the building when they took away the scaffolding for the roof.

As for steel life I think it really comes down to the environment it is stored in and its use. With real bad environment it can be gone in minutes, with storage in an optimal environment it should last forever. I do wonder what museum people consider optimal storage environment though? There are likely differences for different kinds of steel.

Glad to see a consensus about the lifespan of steel, because I don’t know about you guys but I plan to confuse the  💩 out of an archeologist someday when they dig me up and find a pile of dust and million and one shiney little tools.

How about The National Park Service "Museum Handbook Appendix O: Curatorial Care of Metal Objects" PDF as a good base document?

Excellent!  :cheers: Where else can you find chapters like "Emergency Procedures for Metal objects".   :D

More to the point it seems I was onto something by covering larger metal objects in acid-free wax for long term storage. (Note: Keep inside something to keep birds and animals away. One year there was small blunt beaked birds flying around, and no wax left on my metal...).

Many museums use Renaissance Wax as a preservative. I use it for revolvers. and it works well. You wipe a light coating on, let it sit a few minutes then wipe it off (like waxing a car). Use it sparingly.

Honestly I was very surprised indeed to discover that my 2 ton cast iron tables had been viciously attacked by swarms of small cute birds. Somehow the chance of that hadn't crossed my mind. In retrospect it should have - I just didn't think of that wax in terms of food at all.

These days I have them covered up proper, and hopefully safe back inside soon :)

Vintage as well?

Real katanas and wakazashis, plus possibly old school wheelguns? Ladies and gentlemen, we may have a Six-gun Samurai in the house.  :D And I"m jealous if it is true.

Yup. Old S&W revolvers, here are some J and K frames.


BTW - I'm pretty vintage as well. Possibly antique.

Nothing that can't be fixed with reblueing and new springs, maybe new grips.  :D

I'm just getting a bit paranoid about my collection, I want to be able to use it for the rest of my life  :D


Well, you get to 40 and then you realise you don't have enough years left to wear out any knife/axe/stuff....

@redmond ........ :drool: ..........  :salute:

Been reading a lot about Viking era swords, amazing what is left after centuries of rust.
