Well I of course went nuts for awhile and tried to sample every DE blade I could find. I therefore feel some obligation to point out that Blue Bird, Dorco, TreetCarbon) and Merkur all without fault shaved terribly!
I have tried most of the Lords, Crystal, All Personna (including the '74), Gillette's and Schick's of various vintages, Feather, Sharp, Wilkinson, Many, if not all the blades from the Petersburg Plant, and even an ancient "Mystery Edge" Blade (ouch!). I think my experience is echoed a few times in this thread!
