Falls under weapons training. Ruby has at least some knowledge on swordmanship in how she had no worries about picking up Penny's sword and wielding it against the Nevermore. This training in a weapon that is not part of her normal weapon would take away time she would otherwise have to learn hand to hand in order to study swordmanship, which she likely picked up because Qrow uses a sword as well and she seriously looks up to Qrow.
