I'm still somewhat new to the DE shaving thing and feel that my technique has gotten alot better, so now I'm trying to optimize my kit. I'm using a Merkur HD and Tabac soap (which I'm enjoying). After the first couple of bad shaves, my last shave on the Merkur blade that came with the razor went pretty well. Tried an Astra Stainless next and it was bloody razor burn city. Right now I'm using a Personna red and that seems to be doing pretty well. The problem is I have a fairly coarse beard, sensitive skin and cowlicks. So what blades have people tried that are agressive enough to deal with tough stubble but gentle enough not to burn sensitive skin. I have Sharp Stainless, Derby, Shark, Astra Platinum, Feather, and Zorrick blades left in my sample pack.
