Shōnai school (庄内) iron tsuba, signed with kao (花押), attributed to Yoshitoki (宜時). The motif is a classic cloud dragon motif. The motif is often described as waves and cloud dragon, or Hatō unryu (波濤雲龍図), implying ocean and sky, but this is an incorrect interpretation. There is a type of cloud which mimics the classic stylized cresting wave in Japanese art (see below). The dragon's domain is a turbulent, billowing, cloudy sky. The motif is well executed with a carving technique termed Katakiri Kebori (片切毛彫). The shape of this tsuba is round, or maru-gata (丸形). The rim is squared, with tiny bit of roundness, Kaku-mimi ko-niku (角耳小肉). The plate is perforated with two small holes called udenuki-ana (腕貫孔), though the NBTHK Hozon papers only describe them as ko-sukashi (小透).
The tsuba is signed with a Kao (花押) on the reverse side, but no signature. Fortunately the kao has been tracked down, and it is believed to be that of a Shōnai school artist named Yoshitoki (宜時), see reference image below.
