I'm echoing some of whats already been stated, but it really can't be stressed enough. I though the same thing about my blade, come to find out it was me. I ended up feeling like a jerk afterwards.

Preperation + Technique=Great Shave. Try a slicker cream, shave after a shower, apply a hot towel for prep, try a pre shave oil, add some other things to your routine to see if its you or the blade. Spend some extra time on your prep. As far as technique make sure your stretching your skin and find the angle. I'm still new at it and take my time, so I relather areas I haven't shaved yet if they dry up a bit.

I'm no pro, but I did learn a few quick lessons with the help of this board and a fellow member here.
