Can't say for certain here -- someone else would need to attest to the Dorco or Personna issue. But I *can* tell you that I hated the Dorco blades I had, but like the CVS blades quite a lot. So my suspicion is they are not Dorco.
I got some at the CVS Pharmacy by my house. They are package just the generic razor blades sold at "Raley's" Grocery Stores in Northern Calif. and Nevada. And the generic razor blades sold in the "Flying J Truck Stops". They are also packaged the same as the generic razor blades sold "Burn's Brothers Truck Stops" Although it's been a long time since I got any in a Truck Stop. Also I would say they give as good of a shave as my favorite Razor Blades "Wilkinson Sword"! I miss driving Tractor Trailer Rigs, Cross Country.
