I guess it's a point of discussion, but it seems to me that Danish freehands have become a classic shape since they surfaced around the sixties. One of the reigning masters of these is Eric Nording, and he makes them all the way up and down the price spectrum from excellent factory pipes to artisan up-market pipes. So maybe the way to phrase it is traditional shapes pre-dating Danish freehands, or something like that. Believe me, I've seen a number of the depressing imitations of this style, but the good ones are ... good.
