OK,
didn't know that this was bought from SRD. If it was, then means all should be OK. However steel is steel, There is no two identical razors blades. I had 4 DD razors, all same series, brand new. All were honed by me but two of them were always giving me problem when shaving. I have sent them to one of the SRP members to hone them. He had same experience as me. So my point is, this is nature made steel which act in many different ways. Sometimes razors are better or worst, regardless where purchased. It does not mean that they can be used. I have one old $3 French razor I bought many years ago and is my best, better than DD, Fili or others...
Sometimes we just have to accept that perfection does not exist...
