In my opinion, that's not a crack, that's a CRACK!
I would consider that totally unacceptable, and I would be disappointed in the maker for sending it out that way. I don't see how anyone could miss that during a basic inspection or consider it acceptable to give to a customer.
What I find most disturbing is that it sounds like the maker has tried to convince you that it's perfectly normal and that you should accept it. Although I'd be a bit disappointed in a maker for sending me a knife in that condition, I wouldn't mind so much if they acknowledged and accepted their mistake and agreed to replace the handle scale without question at their own expense. Mistakes can be forgiven if they are properly remedied in a professional manner.
