There were other weapons used back then too, such as axes, polearms, missiles, spears, and blunt implements. To an extent, these weapons have been somewhat represented in fiction - Saint Cuthbert from Greyhawk carried a cudgel and apparently whacked non-believers with it. David killed Goliath with a sling. The Greeks and Romans preferred thrusting weapons like spears and javelins and I believe used swords as a fallback when their primary weapon was unavailable. A barbarian tribe called the Franks used a cool throwing axe called a Francisca to break up an enemy's shield wall before charging. During the late Middle Ages and early Renaissance periods, pikes became a mainstay of European armies until they were replaced by bayonets.
I guess if I had to tack a point onto this post, it would be to consider alternatives when creating a character for a fantasy story or an RPG. It'll certainly add a level of uniqueness that will set your character apart from others.
