life saver

Someone or something that provides crucial help in a difficult situation. The term is almost always applied to situations that are not literally life-threatening. You're a real life-saver for coming over and fixing my flat tire. The knife I brought on the camping trip turned out to be a life saver when we realized we had forgotten a can opener.
