DH has no problem with me using his drill/screwdriver/saw/etc, but I can never find them. He is incredibly disorganised has a storage system that I do not understand (mainly along the lines of "I'll just put this here" from what I can tell).
It seems wasteful to have two sets of basic tool items, but I have visions of drill bits all lined up in size order, little drawers of screws....
Perhaps the larger issue at play here is the double standard, because he would not be allowed access to my tools AT ALL.
