Sounded thin. You made me check. My eraser shield, probably from the
'60s, seems to be .0051" . (I have no way to measure just the areas
close to my most frequent mistakes -- maybe a bit thinner.) Another case
of the cheapening of modern products?

Hmm. Just noticed there is a very slight cylindrical curve to the
device. I was never instructed about that, or forgot, seems the proper
application would be convex down?

I don't think the curve was intentional. I think it was a result of
punching all of those fancy shaped holes. My recollection is the concave
side has all sorts of sharp burrs that will eat your eraser PDQ. I always
used mine with the concave side down.


Oh, that's what he meant. Yes, one side is rounded a tiny bit and the
other has a sharp edge.

When we moved out here we briefly had an apartment and thus cable TV.
Then I discovered that there was one Episode of Gilligan's Island every
morning at 6:30am or so. My wife said that I've got to be kidding...
