Sword wiki:
Old English sweord; akin to Old High German swerd, lit. "wounding tool", PIE *swer- "to wound, to hurt") is a long edged bladed weapon, consisting in its most fundamental design of a blade, usually with two edges for striking and cutting, and a point for thrusting, and a hilt. The basic intent and physics of swordsmanship remain fairly constant, but the actual techniques vary between cultures and periods as a result of the differences in blade design and purpose. The names given to many swords in mythology, literature, and history reflect the high prestige of the weapon (see list of swords).
