Om Muramasas magiska svärd skriver Ishida (Dictionary of Basic Joseki 2 sid 120): "Black 1 and 3 are the frightening combination known as the 'magic sword'. However, if White checks that the ladder is favourable, he will never get a bad result." Trösterika ord!

	I Tales of Old Japan (1871) av A.B.Mitford (Lord Redesdale) kan man läsa: The swords of Muramasa, although so finely tempered that they are said to cut hard iron as though it were a melon, have the reputation of being unlucky: they are supposed by the superstitious to hunger after taking men's lives, and to be unable to repose in their scabbard. The principal duty of a sword is to preserve tranquility in the world, by punishing the wicked and protecting the good. But the bloodthirsty swords of Muramasa rather have the effect of maddening their owners, so that they either kill others indiscriminately or commit suicide.
