. . . this is my Nihonto katana. I received it after my grandfather died in 1957. It was a prominent feature in his "doghouse" out back by his workshop.
Information on the origin of a true Nihonto is recorded on the tang (nagako). One side of the nagako usually has the date (nengo) and the other side has the smith's signature (mei).
This is the mei or swordsmith's signature. It reads "oiete toto hizen no kuni Tadamitsu tsukuru kore," which means: "at Tokyo, Tadamitsu of Hizen Province made this".
This is the nengo or dating of the blade. It reads "Showa jyu hachi nen san gatsu kichi jitsu," which means: "on a fortunate day in March in the 18th year of the reign of Emperor Hirohito," (March, 1943).
. . . and yes, it will cut bacon. Not a good idea, though. Legend says that a Nihonto, once drawn in anger, cannot be sheathed without drawing blood.
I must go and sheath it now. Done. OUCH! Wait. I wasn't angry.
