D&D 2014 spell: Mending. Source: Player's Handbook (2014). level 0, school Transmutation, casting time 1 minute, range Touch, duration Instantaneous

This spell repairs a single break or tear in an object you touch, such as broken chain link, two halves of a broken key, a torn cloak, or a leaking wineskin. As long as the break or tear is no larger than 1 foot in any dimension, you mend it, leaving no trace of the former damage. This spell can physically repair a magic item or construct, but the spell can't restore magic to such an object.
