mender

noun

1. A person who mends.

   “The face of the old umbrella mender lighted up with a kindly smile as he commented on the strange conduct of my umbrella in slipping a cog just as he happened to come along. I asked him by what evil magic he did the trick and he laughed in a half-hearted way just to be polite, but it was plain that he had long since forgotten how to laugh.”
