peice of piss, get your thump on one side of the clasp and your index finger on the other.

bend the index finger like a u so the the \ _ / flat bit is the other side

pinch the clasp up a little bit

then twist it

i usually use my right hand soooo i twist clockwise, i dunno if in american the clasp is different.

if its just simple hook usually u dont ahve to twist just pinch a little harder

then let you hand go and viola
