That's if you have 2 tools. Then you can combine them to turn them into one tool, and the tools' durability will be added together, plus 10% bonus. This is generally not a good way to repair tools, especially valuable ones. Also, they do not need to have the same durability.
ok but if the one is less durableity is lesser than the other one,it will not completly an unused tool
