From a previous topic: 
http://answers.google.com/answers/threadview?id=25551 we learn that
there are two factors affecting the life of a disposable razor blade:

1. Abrasion of the blade due to gradual "rounding over" of the blade
by contact with hair

2. Rusting due to oxidation

There are now several products out there that seem promising, but also
could easily be snake oil.  The two main types of products I am
curious about are:

1. Cryo-treated razor blades, such as those you can purchase from
GreatRazors.com and RazorMax.com.  Allegedly, the unopened product is
slowly frozen to a temperature of -300 F thereby strengthening the
blade and thus extending the life.  This would seem to reduce the tear
on the blade from cause #1 above, if legitimate.

2. Oil immersion solutions, such as those offered by RazorMax, which
agree that oxidation due to water is a major problem, and offer as a
solution a device which is used to immerse the blade in a lubricating
oil which separates water and hair bits from the blade.

I would be very curious as to whether these products have been tested
scientifically or by any sort of reputable source.  And of course
whether the science is remotely valid.

Obviously, I would also like to know if, for example, the cryo
treatment is a total placebo or scam.  I was somewhat impressed by an
ePinion where someone did a scientific-ISH study, but would like a
little more convincing evidence before spending around $30.  From
browsing google groups, I see that metallurgists and knife enthusiasts
have very mixed opinions about the usefulness of cryo-treatment.

I can find little or no information about the razormax oil submersion
product.  It would seem that similar products exist.  What
alternatives exist and how legitimately useful are they?  This seems
like the more promising solution, given that similar ideas exist, such
as the Braun electric shaver which is submersed in a cleaning solution
(according to TV commercials, anyway).

stephenvakil-ga, 
     I don't know if the oil immersion products work.  But I have
tried a very cheap alternative that does: baby oil.  I store my razor
in a plastic glass that has a lid.  This keeps it from evaporating. 
This technique extends the life of the blade at least once (if it
normally lasts for one week, then using this technique makes it lasts
two weeks).
