I like your post knifeguy, especially if you are talking about a Custom.
I would expect a Custom to come from the maker as sharp as it can possibly be. In fact, if it came straight from the maker, it should show the full potential of the blade as it should be realised by the maker. Really, if you are the maker and you don't show the blade to its full potential, then who in the world do you expect to do it?
I call it pride and ownership of work and a simple responsibility to your clients.
Whether the end user is able to sharpen a knife properly or not is irrelevant.
I paid for a Custom knife and I expect it to be made to the best of the maker's ability and this best would obviously include the sharpest edge possible because what good is a knife if it can't even cut properly?
My $0.02 rant...:D
