Great review! I've read somewhere that with very sharp blades like the these 7 O'Clocks, Feather you should makes a few passes on each side of the blade on an old pair of denim jeans. They say it will take out the harshness of that first shave.
I would do that except I rarely get more than 3-4 shaves from any blade, so I fear that stropping the blade might shorten its life. I have heard of running the edge across a cork will also remove the coating.
