The quality of being at hand when needed

Usage examples of handiness.

Or even say a father who is extremely handy around the house and can fix anything, and has the son help him, but gets so engrossed in his projects (the father) that he never thinks to explain to the son how the projects actually get done, so that the son's "help" never advances past simply handing the father a specified wrench or getting him lemonade or Phillips-head screws until the day the father is crushed into aspic in a freak accident on the Jamaica Way and all opportunities for transgenerational instruction are forever lost, and the son never learns how to be a handy homeowner himself, and when things malfunction around his own one-room home he has to hire contemptuous filthy-nailed men to come fix them, and feels terribly inadequate (the son), not only because he is not handy but because this handiness seemed to him to have represented to his father everything that was independent and manly and non-Disabled in an American male.
