and I nicked myself, again, a question of the obvious struck me. How do
they sharpen
razor blades? The thingies stay sharp for a month or more. [I do not shave
each day.]
Those thingies must be made and sharpened in the millions every shift. Are
there any
clues in their secret methods which would be helpful to woodworkers? I am
just
guessing now, but I think the makers use a procedure with a narrow steel
alloy ribbon
about a mile or more long, then sharpen one edge of that ribbon on one or
both sides,
then blank out the individual blades. Assembly would then be a piece of
cake. How do
they sharpen that edge?


And why do they not use the same materials after the product has been on the
market for a year or so. 4 or 5 years ago I got a sample razor with 2
refills IIRC. It was a double blade coated with near microscopic diamonds.
No kidding, I used the first razor for 1 year, but not shaving every day,
before changing to one of the refills. The refills lasted quite long also.
When I bought replacements, I was less than impressed. 1 month was about
it.
