Here I looked at some swords from Oakeshott’s “Records of the Medieval Sword” and picked out the more bizarre/interesting elements: atypical pommels and crosses.
After a while, I have come across the revelation that, out of the melee weapons (or weapons based on historical designs), maces are the most versatile (though flanged maces seem to be an exception, and I will expand on this in a future update). As long as the top is heavy, there are few limitations to the form. This page explores this idea:
Finally, a short exploration of curved blades and crossguards. A lot of the blade shapes are based on falchions, which, put simply, are weaponized cleavers. They work differently to straight swords and are a sort of middle ground between swords and axes.
