The "weight of the blade only" is a term frequently used. I think the problem can arise if it's taken literally. The way I visualize "the weight of the blade" in a true literal sense, it would be separating the blade from the scales, laying the blade on the hone and simply pushing the blade along from the back of the spine with some object that would only provide lateral momentum and absolutely no downward pressure. Thinking of it that way, I don't think I'd ever want to hone a razor again for lack of enjoyment. No one is advocating that.
