37" OAL, 25 1/2" shin gunto pattern hilt and saya. The tang has one mekugi-ana, with 3 blue paint figures on the right, a Seki Arsenal stamp and carved 4-symbol signature on the left. A consignor-supplied translation suggests "Atsumori Yamada" as the smith, but not record can be found for a smith by that name. Good overall with the blade unprofessionally polished.
