If a dwarf bent a longsword over his knee to have a curve and convinced a druid that it was really a scimitar, would the handle of the blade erupt in the druid's hand and cause him excrutiating oath-damage?
Furthermore, being made of metal, what exactly distinguishes a curved sword from a straight one in light of druidic oaths? Are swords in fact naturally curvy in the wilds, becoming civilized when straightened out flat?
