Skeleton wiki:
>For other uses, see Skeleton (disambiguation). In biology, the skeleton or skeletal system is the biological system providing support in living organisms. (By extension, non-biological outline structures such as gantries or buildings may also acquire skeletons.)Skeletal systems are commonly divided into three types - external (an exoskeleton), internal (an endoskeleton), and fluid based (a hydrostatic skeleton), though hydrostatic skeletal systems may be classified separately from the other two since they lack hardened support structures. Large external skeletal systems support proportionally less weight than endoskeletons of the same size, and thus many larger animals, such as the vertebrates, have internal skeletal systems. Examples of exoskeletons are found in arthropods, shellfish, and some insects: the skeleton forms a hard shell-like covering protecting the internal organs.

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).
