There was only supposed to be 4 blades per pack but there was 5 in each of the Twin packs.
Maybe from the 2 cutting edges? After I was done I put the razor in my ultrasonic cleaner to clean it.
Something that I notice was both blades felt like it was dragging a little! With the shim in place it makes the razor a little more aggressive.
Has anyone tried a Twin Double Edge razor blade before.
Well they do shave I am not sure they live up to all that the package states but they do shave.
I bought some of the Schick twin 2002 from E-bay awhile back I have only used 2 blades so far.
