Are they Shave Ready from the manufacturer, or not?

[Slur]

Dear Gentlemen,

I am a Greek straight razor shaver. In my country there is a shaving forum with a few members.

The reason I am opening this thread is to have some expert opinions about a debate that we have in our Greek forum.
Some of us, including me support that a new straight razor, especially a new Dovo or a Their-Issard is actually shave ready from the manufacture, while others support that these razors do not come shave ready from the manufacture, and they always need professional honing before shaving.
I base my point of excellent manufacture’s honing on my experience with a new Dovo Bismarck 6/8 which was indeed shave ready from the manufacture, and the edge is the most perfect I have ever seen. However, other members from our forum insist that they also bought a new Dovo straight razor (one member in particular bought the “Best Quality” Dovo straight razor) and it was absolutely non-shave ready.

Since this forum (SRP) is the largest worldwide in regard of straight razors, I would like to have some opinions regarding your experience with new straight razors and especially Dovo or Thiers-Issard but not only.
Do they come shave ready from the manufacture, or do they not ?
I cannot believe that some of them are shave ready and some others not. It does not make any sense to hone professionally some of them, but not all of them.

Thank you very much.
