(edited this one a bit)
Moonblade was made by Tsukiakara at age nine. It glows a blue light. If Tsukiakara dies the sword will destroy itself. It cannot cause external injury to living things, only internal. For instances if it was to scrape someone the skin would not be sliced and bleed but the blood vessels would and the person would bleed from the inside. Any nonliving material Tsukiakara avoids using this sword mainly cause it can be used against him.
Lifeblade was made by Tsukiakara's mother and was giving to him when he graduated into genin. It cannot kill. Instead it will heal any area it slices or stabs and will leave no mark or scare. It can heal anything from heart failure to the smallest plague build up in the veins. The only down side is that the patient/victim will still feel the pain as if they were stabbed or sliced. The sword can't revive things that have never been alive or have died for more then 2-3 minutes.
