If Jillians sword could be resized, as people are suggesting, I would expect that the scaling would be linear, that is that all proportions would be maintained.

That would greatly decrease the usefulness of the weapon. The last thing you want in a stabbing weapon is a wide blade with a relatively blunt end.
