Actually curse swords are initially just magical tools imbued with malice, nothing about them breathing or thinking is mentioned. Its not until they fuse with someone that they become "alive" as a fused being.

Tsukumogami on the other hand are basically based on the mythic idea that magic and emotion can grant life to inanimate things, giving them functioning bodies (one can assume things like the chochin obake have a heart and lungs or some equivalent).
