I noticed that the Derby blades have the edges numbered, are you supposed to flip the blade after a bit? Does this really help?

Hello,
The numbers mean ziltch. Flipping a blade over is not advised, as the edge is already dulled. It doesn't matter which #'s are are showing when you load the blade. Just follow your normal routine of 2-4 shaves w/a blade and load up a new one.
Regards,
If confusion is the goal they are very successful..
its been discussed somewhere before I think. I seem to remember somebody emailing a blade manufactuer and finding that the numbers are only for the internal QA procedures etc.
I think it was also agreed that flipping a blade was bad, I cant remember exactly why though.
