Thank you for viewing. This is a tsuba by Kofu Jushin. ♦Size♦ Length: Approximately 7.8cm Width: Approximately 7.0cm Thickness at the seppa-dai: Approximately 0.5cm Thickness at the mimi (rim): Approximately 0.4cm Weight: Approximately 129g Material: Iron (Please forgive any errors as these measurements are approximate) I have not seen any other works by Jushin with a date on the back like this one, which reads "Kansei Ni Inu Hachigatsu" (August, 1790), making it an interesting piece from a historical perspective. The box inscription includes a red seal that reads "Ikariya Zo" (Collection of the Ikariya family), and the clean, openwork design along with the signature guarantee its authenticity. *Please refrain from purchasing if you are concerned about minor details, as this item has been stored at home. Please examine the images carefully before considering a purchase. ♦Slight price reductions are negotiable.
