This was info on the sword when purchased: This prized family heirloom is a 17th century Japanese katana, liberated in World War II by the father of its current owner. The age of the blade was determined by the curator of the Asiatic collection in the Boston Museum of Fine Arts. The tang is not signed; this is rare, but not unheard of, according to the curator. At one point the handle was disassembled in order to see the last word and testament from the samurai that owned it, which is written on the inside. The Fred Lohman company was tasked with restoring the handle in order to keep the menuki and tsuba in the excellent condition they have retained over the years. The handle is made of sting ray skin wrapped in silk. There are several small marks on the blade; they look like they might be from blood eating into the finish.?˜The katana measures 34.5 inches from the tip of the blade to the end of the handle, and 25 inches from the tip of the blade to the tsuba. The tsuba is 2.5 inches wide and 2.75 inches long.
