Sachiko does not use any of her own jutsu. She has special twin katanas (trying to find a pic) which is specially made for her. They absorbed any attack that person sends on her, and she is able to release the attack back onto them. The plus side of this is that Sachiko is able input her own chakra into the attac to make it bigger, or else the attack is as powerful as the person who had originally delt it. The only draw back from this is that she can not absorb kekkei genkais, and she can only hold a specfic amount of attacks in her katanas at certain times.
Is this enough information?
