What do the different marks on the knives mean?

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.
