Mu teki “without rival.”
Mitsuboshi Trademark symbol for “three stars,” registered in the 3rd year of the Keicho Era (1598). Originally shown as 3 circles because to the founding Yoshimoto bladesmiths, stars in the sky looked like little round dots and not the 5 pointed geometric shapes we have come to know in North America. It has been modified in our current logo to reflect the way the stamps usually look in a forged blade when the hardened stamp is hammered into the softer blade at a slight angle, resulting, ironically, in something resembling a moon.
