Think of an ancient hamlet where edges were traditionally all highly polished and smooth. The first person to suggest a serrated knife edge or a saw must have faced ridicule. (or worse for blasphemous thinking).
In the hamlet in the next valley, where edges were traditionally sawtoothed, Imagine the poor radical who suggested highly polished, smooth edges.
