Three MONTHS??????!!!!!!!! -- must come from living in Northern Utah --
Down here in Sanpete I am lucky to get one day per Atra blade.  I use
yesterday's blade once over then load a new blade and start shaving.

Hence my question: Why does a shaving blade get dull?  The only reasonable
response thus far is that this wimpy string of protein bends the edge of a
piece honed steel.  Such metallurgy is hard to understand.

Yes, and my blades have a strip of Teflon like stuff which is supposed to
make the blade last longer.   As far as I can tell it just makes it harder
to shave.

Just me over here in my little corner.
