I have a razor (carbon steel blade) which has been
giving me good shaves for years, but which suddenly
"went bad": pulling, tugging, wouldn't cut, etc. So I
gave it a few laps on a Swaty and had a look at the edge
with a magnifying glass.
There appear to be several very tiny pits near...but not
on...the edge.
I tried to shave with it again, and the edge worked fine,
but only for about 1/4 of the shave...then it went south
again.
So I touched it up again, etc. Same thing happened.
I'm suspecting that those tiny pits are a sign of edge
corrosion, and that the blade just won't hold an edge
anymore.
My questions are: do the pits indicate a "deeper"
problem? Does the apparent corrosion extend beyond
what is visible?
And how far back would I have to hone the edge to
cure this problem? How far back is the "good steel"
likely to be?
Sorry, I can't send any pictures, but I sure would
appreciate some help here.
Thanks,
Paul
