For a lack of understanding of how to get this question answered, if there is and answer, I come to post here in the hopes an answer will arise.
"A Blade once sharpened, then put away, unused, does time eventually cause a blades edge to loose its sharpness?"
This is a demonstration that no matter how long you have been doing a thing there is always something you can discover about a thing.
Nothing in the universe remains static.
It honestly depends on the storage
If there is air getting to the blade then there is the possibility micro corrosion on the Fin could actually dull the edge
If the air passes through a Desiccant barrier and there is ZERO moisture then the edge should stay just fine for years..
ie: It isn't "Time" it is "Moisture" that can dull a blade...
That is my understanding so I am sticking to that story :p
Time/ age dulls everything.
Just look at ourselves.
Has anyone on this forum used a previously unopened pack of very old vintage double edge blades? I haven't. If anyone has this experience, and found the blades perfectly sharp, that would be some evidence that Time does Not Dull All Blades.
Anyone?
Yup, dull after a lot of years for some blades. Rusty on the supermarket shelves for some new blades.Quote:

I sent one to GSSIXGUN to experiment with. He too found that it gave a decent shave and was going to experiment further however he found a small crack so that plan was canceled.
All of the razors were darkened by time but none were showing any sign of rust. All had been stored dry in a drawer far from the bathroom and kitchen.
The Japanese razor that Owen Agenbroad had found during the battle for Iwo Jima still gave a decent shave after 65+ years of similar storage and later stropping.
Based on my experience with the above razors I think that the lack of moisture is the key to proper storage.
I got a 9/16" Henry Sears & Son with barbers notch at a auction that was very sharp & in almost new condition. Was told by the former owners daughter that it was kept in a drawer next to the owners bed for around 40 years. & never used in that time. I always try my razors before I work on them & I got a great shave with out stropping it. Later I did a light honing on my coti under running water till the blade stuck to the stone, stropped it on Jager Shell strop & WOW is all I could say.
When I got my 16K Shapton the other day I got out the Sears razor, gave it a quick strop & shaved half of my face. Did 6 round trips on the Shapton & stropped & I will say you could do surgery with this razor now.
So I will say a properly stored razor can keep its edge over a long period.

Look at a bevel, with magnification, after you have shaved, cleaned it and put it up.
You will see, bits of soap, skin, hair, and blood, all of that contains moisture and will cause oxidation, (rust), unless the razor was stropped.
Yes, had a similar experience as Slawman did. I recently got a Heartring razor advertised as "possibly" NOS. It came in a mint coffin in it's plastic sheath. The blade felt a little tacky so I cleaned with some alcohol, stropped it and had a surprising good shave with what I can only guess was the factory edge after all those years. A few swipes on a 12k Nani did improve it a bit but not hugely.
I would have to agree that the drier a blade is stored the longer it will remain sharp and that it is amount of moisture content in the air that will determine how quickly the edge degrades over time.

I have used some 40-50yr old DE blades that were stored properly (apparently) and they shaved as good as new.
Let me reword your question:
"A razor blade made of carbon steel, once sharpened, then put away, unused, does time eventually cause the razor to corrode?"
The (to me at least) obvious answer is: That depends on how the razor blade is protected.
As you mentioned no protection whatsoever, a blade in that case will corrode in any environment that has a normal level of humidity and thus lose its edge.

Speak for me yourself Outback. I'm getting sharper with each new grey hair. :rofl2:Quote:

It doesn't take much effort at all. My main concearn is the soap because it can really hold the moisture.Quote:

No argument there. It depends greatly on what the normal level of humidity is in any particular environment. In my environment at home if you dry your razor properly after use and store it outside the bathroom it would take a very, very long time for the edge to degrade to a noticeable degree. Other home environments in other parts of the world the degradation could be/is much quicker. It's probably more of an issue in long term storage and you have to take the appropriate precautions.Quote:

Sounds reasonable to me. I have some stored in a supposed air tight box with moisture absorbing media in the box. Little cans that came from my hearing aide container where I store them, but got a new one and did not throw away the little original cans. Argh! They turn rather rapid and I have to dehydrate the little sucker monthly.
I bought 40 five packs of Don Juan DE blades last year & they shave great. From what I can tell these were from the late 40's-early 50's era. Shave great! Some have a rust spot that is always in the same place that just wipes off.Quote:
