The rubbing

Oshigata of Bizen Osafune Sukesada: outline and ridges in graphite, the tang rubbed whole, the hamon drawn by hand.

(i.)Hamon. Koshi-no-hiraita choji midare.

(ii.)Bōshi. Midare-komi, short return.

(iii.)Grain. Itame mixed with mokume, midare-utsuri. The grain is not drawn on an oshigata; it is in the written record.

(iv.)Tang. The signature 備州長船祐定 (Bishū Osafune Sukesada) is cut into the tang; incised strokes take no graphite, so they show white.
