The Dovo you are looking at is machine made, and may not be shave ready if bought from a retailer who will not inspect and, if necessary, enhance its edge.

So, Revisor, or Aust. Both will come shave ready from the manufacturer*. Friends of mine have sold hundreds of them, and there never was a problem.

Just for the record, both Aust and Revisor carry stainless steel razors if required.

* The term "factory" is entirely misleading. Aust and Revisor are two of the three remaining Solingen manufactures, whereas Dovo is actually a factory.
