How often should you replace your blade on a Gillette Fusion Manual or a Power if you shave your beard once every day?

The difference in the BLADE is ZERO...first of all. Second, how often you replace will depend on how tough your beard is. For some it will last for 3-4 weeks and for some it may last even longer.

I have tried the power blade on the regular razor and the regular blade on the power razor (batteries are usually dead anyway)...they both work equally well and last equally long.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
