1. Rate of Oxidation of the metal of which the blade is made
increases with temperature.
2. Cold water makes it more difficult to get a clean shave,
necessitating more razor strokes per shave, thus increasing
wear on the blade per shave.

I keep an electric kettle in the bathroom and submerge the head of my
(cartridge) razor into boiling water before every shave; it seems to make the
shave closer...when I'm not using the razor, I store it with the head submerged
in witchhazel and the blades practically last forever....
R H "and that's without a pyramid" Draney
I don't rememebr if they were still using the old carbon steel
razor blades during the Viet Nam war; we certainly were when I
was in the Army 1960-63.
For those guys out there too young to know, the old razor blades
became unusable after must one shave, or if you were really tough
you might get a second shave out a blade. This was because the
steel oxidized ("rusted") and took the keen edge. Which is how
King Gillette got rich: anyone using razor blades had to have a
new blade almost every shave, and bathroom medicine cabinets had
a slot in the back to shove the old blades (I envision that the
space between the walls got deeper and deeper in rusting blades).
So those who didn't want to spend a lot on blades came up with
all kinds of ways to conserve the blade's edge, but no matter
what you did you weren't going to get more than a few shaves from
a blade.
Then Wilkinson Sword came up with the almost obvious idea of
making razor blades out of stainless steel (which probably had
King Gillette spinning in his grave). At first the blades were
produced as replacements for regular blades, and we kept our old
razor/blade holders. The blades lasted a long time. A week or so
on a single blade. Which was like heaven for the morning shave.
Ironically, Wilkinson had to pay royalties to Gillette.
Finally, it was realized that the blades lasted long enough to
economically incorporate them in a plastic throw-away holder,
and now you can't hardly find old-style single and double-edged
razor blades to put in oldl scrapers and crafts tools anymore.
So, which kind of razor blades are we talking abuut in Viet nam?

I've done bathroom remodels where I had to take out the medicine
cabinets[1] out and open up the walls. The piles of razor blades are
disappointingly small. If I had thought of it, I could have kept records
based on how old the house was and how many razor blades there were and
what kind. Interesting in a geeky sort of way, but I can't recall any
details that would make this more interesting.
charles, uses a cartridge razor and they won't fit in the slot.
[1] I just look at my medicine cabinet (apartment built in the 70's or
80's, I think) and it still has the slot. If I remember, I'll check Home
Depot and see if new cabinets still have the slots.

The el cheapo plastic safety razor with even more suspect blade that was
designed post WW II lasted, more as an NSN [1] than as something anyone
actually ordered, at least until 1985. By the late seventies, the
Quartermattress Corps was almost out of the personal hygiene business,
preference was to push the PX system further forward.

Rich *&%^. Whatcha did was take the blade, and a relatively straight-sided
water glass, and you sharpened the blade by pushing it against the inside of
the glass and rubbing it back and forth. You could get a month out of a
Gillette Blue Blade [2] like this. The same effect could be achieved with
emery paper and the inside of a canteen cup.
> This was because the

Which is why the blade sits in alcohol at home (as someone (Mr. Draney?)
mentioned above, witchhazel - *real* witchhazel [3] - was a good choice), or in
WD40 or RBC[4]-soaked cardboard in the field.

Supposedly Gillette was directly inspired by beer bottle tops: very cheap,
tiny profit margin, but used by the millions, and only used once.

Yup. A real hazard to remodelers, often migrating, thanks to plumbing access

The last hold-out of double-edgery in the US seems to have been New Orleans;
when I finally gave up on 'em in '95 ot '96, that was the last city I knew of
where they were still found in large numbers in markets.
Never had any problem finding single-edgers, but they are now viewed as
painter's tools, not as grooming impliments. Never had to look past the first
hardware store.

Here is the ironic part. They were made of stainless, not because it
did not oxidize, but because it had to be stainless to make it through
the process of Teflon(r) coating. It was that coating which made them
last longer. The actual cutting edge was not as sharp as the Gillette
blue blade technology. Because the TFE prevented wear, the edge lasted
longer. The TFE was not advertised as a feature until Shick figured
out how to do it.
I have this from a former Gillette Engineer. They discovered this when
they tried to do metallographic cross-sections of the Wilkinson blades
and got smearing fom the plastic coating.
Also, Wilkinsons were initially sold in hardware stores as a promotion
for their SS garden tools.

From What I have Seen, which might be a smaller and less significant sample,
people tend to use the slot a lot less if the actually live there, and plan to
for a while. Barracks and dormitories, they get used. Apartments, less so.
If you might be the guy who has to take 'em out in 10 years, they go back in
the the other side of the razor dispenser as God intended.

I clearly remember in Army ROTC, circa 1958, the instructor
talking about ways to make things last longer, and he gave
us the instructions about resharpening our razor blades on
the inside of a glass tumbler. Said you could make the blade
last about 10 days that way, instead of the usual two. Must
have been talking about the carbon steel blades, which is what
I used when I started shaving in the early 50s.

The other half of the King Gillette formula for success was Give away
the razor. A strategy Gillette is following even today, even though
blades last much longer. A Mach III razor is cheap, but when you
start replacing the blades you spend real money.
One might also add that Hewlett Packard seems to understand this very
well in their marketing of printers as well. We just got a beautiful
color LaserJet 4650 with a duplexer for less money than it will cost
to keep the thing in toner cartridges for a year.

Everyone knows that the best way to keep a razor blade sharp is to
store it under a pyramid. Unfortunately the cost of commuting to Egypt
outweighs the savings on blades.

When I finally ripped apart the wall behind the bath at my mom;s
house (looking for the godz only know what) I found a pile of
blades that was about 8" high in the cavity behind the studs -
not solid, as not all had fallen perfectly flat. The vlades
were mostly rusted and the whole "pile" crumbled as I poked at
it with a small whisk broom.
More interesting, perhaps. and even less OnTopic, when the house
across the street from my house was remodeled, one of the walls
in a "lean-to" shed construct (which housed the laundry
machinery and hot water tank) was found to contain thousands of
beer caps. 30+ years worth of serious evening imbibing by the
prior owners. A bottle opener, similar to the ones once found
on soda machines, had been mounted on the wall - and moved
about, as the spaces between the studs filled up - for
convenience, and was much used, evidenced by the rounding and
wearing away of the central tongue.
Some caps were quite rusty, others were almost pristine.

Lexmark is the master of this in the inkjet business. They use patented
technology in their injet cartridges that keeps competitors from offering
knockoff products, like they do for the other brands. Their printers
won't work without the patented whatzits in the cartidges.
The cellphone market works according to the razor model too. They give
you a free or steeply discounted phone, but it only works with their
service, for which you pay many times the price of the phone over the
life of the contract.

Didn't they just lose a fight over this (very recently)?
HP does the same thing in their inkjets, at least, and I Was Told that the
modern DeskJets recognize serial numbers in the carts and won't accept
refilled ones. If that's so, we're on our third and last; our first (*my*
first, as this was before our marriage) was the original DeskJet (back
when they cost $500 or so).

Old scrapers? My supermarket sells the scrapers brand new, and also
sells the single-edge blades for refills.
So does Home Depot and Lowe's. One of them even sells boxes of a
hundred blades. Or maybe that's Lee Valley. I know, because I bought
one.
I think that Baker's Catalogue sells the double-edged blades as
refills for a lame' (edged tool to cut slashes in bread loaves). I
haven't seen double-edged blades for a long time, though, but I really
haven't looked. I found one on site when they were building our
house, though, so they must still be available.

Yes, HP does the same trick. I buy refilled carts from a local dealer
who replaces the chip on the case...gets them from some guano island
in the Horse Latitudes. He charges about 2/3 the OEM price.
The firmware in the printer typically tracks the cartridge ink level
by counting the inkjet pulses delivered to it, and stops printing
after a certain number of pulses. My HP Dl35 (multifunction
printer/fax/copier/scanner) also declares the cart dead as soon as you
replace it for ANY reason...buy two carts, print one page with cart A,
switch to cart B, and the printer will not use cart A again.
However the printer only stores three "dead" serial numbers, so you
can defeat it by keeping some used carts around.

I still use the double edge blades to shave. I think my last purchase was
made by Schick. And my razor of choice is made by Gillette. I have an old
schick razor as well, but I like the Gillette one better. This is the last
razor my grandfather bought. I really have no idea how old it is, but I
would guess early 70's from the looks of it. I use that and Burma Shave
disk to lather up every morning to shave.
You can get a 10 pack of double edge blades for about $1 at the local
Kroger's store. That is a hell of a lot cheaper than paying about $3 for a
new cartridge to one of the those Mach 3 Power things.

[Not a lot to do with razor blades....]
I have several Epson printers. They regularly indicate that
the ink cartridge is empty (and I speculate that they do it
in a similar way to that mentioned in the above quote).
A pal told me that this quite simply didn't have much
relationship to the amount of ink remaining.
So, when I'm told that a cartridge is empty, I obediently
remove it, and put the same one back in again. I only
*really* remove it when my own eyes tell me that it isn't
printing. I estimate that I've almost doubled the amount of
use I get from the cartridges.
I also buy compatibles (never had any problems at all), so
that further makes things less of a rip off.

Nothing is Beatle Proof!!
Possibly this relates to /different/ HP cartridges but there are detailed
instructions on how to 'fool' a cartridge into thinking it's a new cartridge
out there. Sort of 'cover contact A, put in printer, take out, cover contacts
B & C and uncover contact A, put in printer, uncover all contacts, put in
printer...'
True enough.
However the _official_ reason is that "Evil Things(tm)"
can happen to your printer if you use it with cartridges
that actually do run physically out of ink.
Now I also used to run cartriges into the ground after
'replacing' them with themselves and "Evil Things(tm)"
never happened to me. The reason why the Things are
particularly Evil for Epson was (As I Vaguely Recall)
that the printer head is separate from the cartridges
and so if it gets bubble locked / gummed up then it costs
big money to replace. That Epsons use use the same printer
head all the time was also the reason a fairly trusted small
computer shop owner told me never, ever, to buy Epson*.

At one point my boss borrowed my Epson and 'helpfully'
bought a replacement /compatible/ colour cartridge as
he'd used up so much of the ink in the /Epson/ colour
cartridge that was in it. The colour was a mess and
after a few prints one of the three colour paths blocked
up completely and never worked properly again.
No doubt that doesn't happen often, but reviews of ink
refill / compatible inks still come up with colour quality
noticably below the real thing.
* But I did, because at the time I was doing printing on
quite thick card which would go through a '120 degree' Epson
paper path but not a '360 degree' HP path.

Just last year I was able to buy a pack of double-edge at
CVS [TWIAVBP - drugstore chain], to use in my two old
scrapers that were designed for double-edge blades. Quite
reasonable price, as I remember. And somewhere, perhaps in
that old shaving mug on top of the glass-front bookcase,
I still have one of the old gilette razors which needs
that type of blade.

I recently inherited an HP Designjet 2500cp. This thing would rather
eat print heads than... well, whatever large printers like to do in
their spare time. But at $600+ a set, I've learned to rehab them.
And to make this suitable for AFU, I heard of a friend of a friend who
knows a guy whose cousin once met a graphic design student who believed
it when shown that his color balancing problems were due to his
ignorance, not a broken printer, and then read the manual.
But I find that pretty hard to swallow.

Yes, the single-edge blade has made the transition from bathroom item
to hardware item...AFAIK, the word "razor" hasn't appeared on their

The local supermarket still has one peg in the razor display that holds
packets of double-edged blades for sale. The "Vermont Country Store" also
sells safety (as opposed to "cut-throat") razors, blades, shaving soap,
mugs and boar bristle brushes for the Luddite crowd.
When I'm not on the road I use a brush-n-mug and a double edge razor.
(Wags who know me will say that the blades must last a considerable length
of time.) On the road I use a single-edge disposable and whatever lotion
happens to be handy.

My HP has separate print heads. It so happens that if the printer goes
a couple of months in a dry climate without printing anything, the
jets clog up with dried ink and you get a message that the heads have
failed and must be replaced.
The manual says that you can clean the head _contacts_ with distilled
water if they get gooey, but never ever let the water touch the
_jets_, lest the aforementioned Evil Things happen. I discovered one
of the Things: if you press a wet cloth against the jets, they unclog,
the head works perfectly again, and you don't buy a new head.

[Paddling furiously with the thread drift]
A couple of months ago I worked on a pilot for a large USAian cable
outlet, a crime drama. For one sequence the Art Department was tasked to
provide a duffel bag full of $50 bills, to be dumped out onto the floor.
Since the budget didn't allow for obtaining that proper quantity of legal
tender they set about to produce unlegal tender, on newsprint in a color
photocopier.
As we've discussed here before, it didn't work. In this case all the
copied bills came out 80% actual size. The solution, as told to me by the
props guy holding wads of faux fifties, was to hire a graphic artist to
scan the bill and enlarge the image to a size that would then shrink to
the proper size in printing.
Props guy offered me one as a souvenir. These were unmodified images of
currency, no picture of Alfred E. Newman on the face, no "For Stage Use
Only" legend. I declined, regretfully, knowing a recipe for disaster when
I see one.
I don't know whether or not this is true, but I do know that our new
HP Color LaserJet 4650, which is new enough that we are still using
the HP cartridges that came with it, occasionally displays on the, er,
display that it is using genuine HP parts. Whether it refuses to
accept other parts I don't know, but it does seem to be able to tell
the difference, anyway.

At Texas A&M (actually, immediately north of) there is "Bottle Cap
Alley."[1] The most popular undergrad bar (The Dixie Chicken) would
throw all their bottle caps in this short alley next to the bar.
It probably would have been impassable, but the Corps used it as a
source of bottle caps to build their "spurs" which they wore every
year before the football game with... someone or t'other. Each spur
supposedly had a number of bottlecaps corresponding to the year.
Eighty-seven in 1987, 88 in 1988, etc. (I wonder what they did in
2000.)

Badger, dammit.
Shaving brushes worthy of their name are made with badger hair. (Though I Have
Heard that a cheap substitute is skunk. I asked a brushmaker -- there still are
a few in Germany -- and he'd never heard of skunk being used. He had heard of
using just about anything else, and bleaching it to look like badger, or using
good bristles around the outside, and something else in the middle.

Skunk bristle? Yow.
TWOSBIStillAFairlyLP it seems and, worthy or not, some are made of boar
bristle. I do have to backpedal on the claim that the Vermont Country
Store sells boar bristle shaving brushes (not only because I can't be
bothered to dig their catalogue out of the recycling bin, but because a
quick Googling suggests that they sell _badger_ damnit bristle brushes).

Didn't someone point out to them that they wouldn't have to throw the
money away after the shot, but could take it back to the bank and get
their money back? Even easier if the money is in bundles, since you
only need two bills per bundle.

Was the current going through the blade, or were there two blades
acting as electrodes with water between them? The latter would
probably work, but the former would almost certainly blow a fuse.

OK, so yes we have all heard about the famous Gillette marketing
theory.
However, this would then cause me to wonder why Gillette used to
sell a small hand cranked double edge blade sharpening machine.
You stuck the blade into a holder, which then was pushed into the
innards of the thing. Then you unfolded and turned a small hand
crank that drove two sharpening offcenter cylinders and a geneva
mechanism that flipped the blade over on every other stroke of
sharpening. The cylinders appeared to be made of hard rubber with
a built-in sharpening ability, somewhat like the hard rubber
polishing wheel of a modern Dremel.
The things are still found on eBay amongst other places.

A cow orker just waits until the local Frys has a sale on cheap Epson
printers and buys a couple. As their ink inevitably runs out, he
just buys new ones, since the set of inks inside the printer will
cost more at replacement than just buying a new printer. e.g. the
Epson C82 and C84 models.
Suspect you are referring to "rugrat crack" distribution theory.

Lexmark isn't the only one. Epson continually wages war with the
non-recommended aftermarket makers... and appears to be underhanded
enough to disable 3rd party inks in a "driver update" in the same
physical printer where that same set of inks worked before.

I suspect that technology has been around every since computer

Good folklore tale, often told, never cited with make and model so
someone familiar with that brand could confirm or deny. Not that
it was impossible to print currency output with any of the
consumer printers in 1994/5 ....

From where I sat in my cubicle by line-of-sight to the money jar of
the floor's honor bar candy and snack table, was only about fifteen
feet. Just to satisfy my curiosity about how people would react, I
printed a proper-sized face-only copy of a one hundred dollar bill.
It provided a few amusing moments when, after wrinkling it suitably to
make it look worn, I laid it face up on the table next to the jar. I
found out that people are funny (hardly news) and that they are
basically honest when they think people may be looking.
Ob UL: I'd heard that the picture of George Washington in the middle
of a one-dollar bill was the part of the image that a change-making
machine reads and accepts. This was before scanners and color
printers, and the UL was that you could take a <foo> cent stamp that
contained the same image of Washington, past it in the center of a
note-sized, blank piece of paper, and get change for a dollar.

I've been told that was a good way to get iron in the diet, but then I
was told, with equal insistence, that it's an UL--the iron does indeed

It would be expected to be less bioavailable than heme iron, but it's my
understanding that there is still some absorption - enough for it to be
seriously considered as a public health intervention.

The brushmaker said that they would work, only not as well, meaning the foam
wouldn't be as nice, and it wouldn't last nearly as long, and that it is much
cheaper. And if I'd like to make my newly-acquired badger brush last, it should
be stored with the bristles *down*. Offered me a widget with a magnet and a
small self-stick washer for the base of the brush. Washer on the base, widget
sticks out from the wall, magnet holds the brush bristles-down. (Lotsa those
things still around, most used to hold soap. Thing like a bottle cap goes in the
soap, and no more soft soggy spot on the soap. Dated, but works.)
I add this only for those who are finished sharpening the blades retrieved from
the wall behind the medicine cabinet and are looking for their next project.

The latter, i.e. wired as a direct short, with the strip of metal being the
resistor, and the water providing the cooling so it doesn't glow and melt away.
But then it'd be 220 Volts, fuse at 16 Ampere, (just possibly 10 A). Then a 16 A
fuse (or circuit breaker) will not blow at 16 amps -- it'll do more than 32 A
without blowing, if the load is on for a minute or less. So plenty of power...

There is what I consider a UL about the Susan B. Anthony dollar. I've
met several people who believe that the awkwardness of the design was a
deliberate sabatoge by Old White Guys who didn't like the idea of
honoring a Suffragette, but couldn't prevent the coin being made. So
they made sure no one would like it.

This was very vaguely based on the gas-rationing coupons made (and never
used, of course) for the oil crunch during the Nixon administration. Image of
Washington from the one dollar bill, picked no doubt to save money in design,
meant that the coupons could possibly be used to rob some bill changers, so the
coupons had to be stored with more security than they might have otherise. If
I remember right, by the next oil crisis, during the Carter administration, the
things were too moldy to use, but too much intact to let loose.
Bill changers can work by image, by magnetism, or by conductivity (or any
combination thereof, obviously), so a picture of Washington identical to the
$1 might have created real problems, depending on how much of the bill a
changer needed. (Some of the patents seem to concentrate on making sure the
center of the bill was present, and that it was continous full length.)
(See http://money.howstuffworks.com/question269.htm for patent linnks.)
Annaloro, Victor E. "Panic at the Pumps," The Numismatist 116.1 (January
2003), pp. 51-52 googles up for the '70s rationing coupon, but I don't have a

Anthony "anybody around here a practicing numismatist?" McCafferty
Just decided to check a specific instance on the HP website. The
prices it lists are pretty much the same as store prices (guess they
aren't playing the "list price/street price" game much any more).
Anyway, there are seven color inkjet printers, priced from $199.99 to
$499.99, that use separate cartridges and printheads. All of these use
the same set of three color cartridges, three printheads and one black
cartridge, at $33.99 each. So the cheapest way to replace a full set
on any of these models is to buy the lowest-priced printer, and the
next model up the line is only $11 more.
Bear in mind, of course, that printheads last through multiple sets of
cartridges, so you wouldn't want to replace the printer just to get
ink. However, it would seem there is never any reason to buy
printheads for these models.

for purposes other than playing expensive X-box games. The hardware is
extremely similar to an ibm-pc-compatible, and you can run linux on it, but
you have to break in to it to do so. Lotsa information available on the web.
No, but I'm resolved that I will *not* come across a strange remote six months
from now and wonder what it goes to....r

Just erase some £1 notes. Piece of cake.

What's the resistance of a razor blade? I tried to measure a single-
edge one, but it was too low for my ohmmeter (less than 0.1 ohm).
The resistance of the blade would be about 0.0017 ohms, if my
cipherin's right[1]. That would draw 132,000 amps on a
resistanceless 220-volt circuit, dissipating 29 megawatts. There must
have been a lot more resistance in the circuit somewhere else, like
maybe in the connections between the wires and the blade. You'd need
about 7 ohms to keep the current below 30 amps.
[1] For those who care, carbon steel has a resistivity of about 10
micro-ohm-centimeters. I assumed blade dimensions of 0.01 x 1.8 x 3
cm. I also assumed that East German border guards didn't have
stainless-steel blades.

I thought HP integrated the print head with the ink cartridge, which is
their excuse for making the cartridges so ungodly expensive.

The resistance of most metals increases as they heat up, so even
incandescent lamps have an in-rush current. What's the resistance
of a razor blade when glowing red-hot?
