i only loan tools to one guy. He returns them in at least in as good of shape as he got them. If a handle is loose, he fixes it. If the blade is dull he sharpens it, uses it, and resharpens it again,before he brings it back. If there are consumables, he buys more than he uses. I loaned him my flooring staplers, and they came back with more staples than the left with, plus some nifty wedges to space engineered hardwood flooring away from the wall.
