Vasher said that there are nonsentient awakened objects, such as the rope which holds things, and sentient awakened objects, such as nightblood. I think however, that all awakened objects are sentient, just the level of sentience depends on the amount of investiture in the object. For example when Vasher awakens his cloak and tells the cloak to protect him, it has to have some level of sentience to obey. However, nightblood had 1000 breaths, which made him extremely sentient. By the way, this is just a theory, and I invite you to poke holes in it.
