During the attack at Pipiroa near Thames, Dixon bilaterally amputated both Ms Butler's hands, which had to be surgically replanted.
She has almost no use of her left hand and about 65 per cent use of the right.
Ms Butler was in hospital for a series of operations, which she said, in hindsight, changed her life.
