I was reviewing my shaving rotation and it dawns on me that seven razors
is a pile of razors. I had eight in the active jar and I find that I reach for
a couple over and over.
Since the OP has a single razor that he likes I would shop for another just
like it and in the next month or so find one or two more better than average blades
to join it. I saw a 'black and white' pair recently and thought that
two identical blades with different scales would be handy as heck.
I still think the OP should call the vendor and explore the details. If this
set is the correct grind, shape etc... that matches expectations then it is a
bargain.
Those that are collecting a seven day set all different may be on to something.
I can see more than one razor swap as the sets are built from parts
of broken sets.
