Hello all, I am taking a stab in the dark with this translation and would appreciate any input. My best amateurish guess is:   紀 政次 (Ki Masatsugu)   My showa references are sadly lacking so I have the internet to rely on for oshigata examples. I would provide more pictures of the blade if I though it would help, but with the thick layer of oxidation and the very tip of the kissaki missing there isn't much else to see. Thank you.   Paul   http://img802.imageshack.us/f/starstampgendeito
