A "hand kerchief" is a kerchief, but it is not for your hair. It is meant to use in hand when making a telephone call and you wish to disguise your voice. You simply place the cloth over the mouthpiece, and your voice will be transformed, having had to travel through the hand kerchief. Well, these days, people have easy access to electronic voice distorters, and no longer have need for the hand kerchief.
