I have recently seen that exact fake etch with complete Rohm facsimile signature for sale with an Anton Wingen laser etched logo.
The tang markings were different, so I agree with Red in that the faker starts off with any available genuine blade.
The faker has tried to be more convincing by crudely grounding off the name in this example!
However, if you do a side-by-side comparison of the etch with a genuine one, the fake is quickly identified!

BTW, I have contacted the seller and he has promised to remove it from his online inventory!
When done respectfully, thus not "crucifying" the seller, it's quite easy to get cooperation.
The focus must be on collectors (especially new people) not getting duped! Nice thread BTW!!
