I have been using a DE razor for a little while now, I am having trouble getting more than 2 good shaved out of a blade, some times I can get 3. I have seen where some people get 4+ out of a blade. I have not tried all the brands I have but so far its not looking great.

I have tried Dorco blades, CVC pharmacy blades, Astra Platinum, and Big Ben in the blue box. best results have been Big Ben as far as number of times used I was able to get 4 uses out of them. The Astra blades seemed very nice for the first 2 shaves but tonight it was like I was pulling hair out with a pair of pliers.

I am able to build a nice lather and I can get the BBS shave on the first and second shave with a blade but by shave 3 it all goes to pot, does this mean I have very rough facial hair and its dulling the blade or am I doing something wrong, I wait 2-3 days between shaves also.
