Here is what Markus Sesko wrights in his book The Japanese toso-kinko Schools, 2012, on page 374:

An artist who worked in the style of the Shimizu-Jingo school was Chisokutei Amatsune (知足亭天常). He was actually a samurai from Yatsushiro who made tsuba as a sideline. An extant old hakogaki of one of his pieces mentions that he died in Edo in the sixth month of An'ei eight (1779) at the age of 73. But the era of An'ei is probably wrong because Chikokutei (sic) is today dated by most experts around Tenpō (1830-1844). His relationships with the Shimizu school or under which Jingo master he had studied are unknown. From the point of view of production time and the finishing of nakago-ana, he is rather associated with the 5th and last gen. Shigenaga who died in the seventh year of Kaei (1854). A peculiarity of  Chisokutei was that he signed his Jingo copies with  "Yatsushiro Jingo Saku" ([八代甚吾作) but added the small syllable "chi" (チ) or the character "Chi" (知) for "Chisokutei" to identify them as copies.

Iron tsuba of round form decorated with the design of a butterfly in openwork (sukashi) with details carved in kebori. Eyes inlaid in brass (one inlay is missing). Unsigned. Attributed to Bizen Shōami school, early Edo period (17th century). Dimensions: 80.4 x 80.6 x 4.4 mm References At Haynes Catalog #6, p. 18-19, Lot 30: "Famous Ikeda butterfly design" (Ikeda family of Inaba and Okayama, and at least 7 other families). Ca. 1700. Shōami of Kyoto, no doubt. Ht 8.2 cm, Th. 5 mm. ["Important tsuba, menuki, bokuto, woodblock prints, koshirae, sword pistol and kana mono". San Francisco, June 1-26, 1983. Catalog #6. Robert E. Haynes, Ltd.] Similar tsuba at Haynes Catalog #9, p.71, lot 143: the classic Shoami tsuba of the mon of the Ikeda family. This example, as most, seems to be made by the same hand as the others. See Haynes sale number 6, lot 30, for an identical example. The eye is brass. From an old French collection. Ht. 7.9 cm., Th. 5 mm. Similar tsuba in the Randolph B. Caldwell Collection, 1994, page 24, №13: "A circular iron tsuba pierced in positive sukashi with a butterfly within an angular rim, details engraved. The eye inlaid in brass [in my specimen the inlay is missing on the omote side]. Unsigned. Bizen Shōami, Momoyama period. Dimensions: 8.0 x 8.2 x 0.5 cm. Similar example: Durand-Ruel, collection Ch. Gilloz, number 1302. [SV: that's possibly the 'old French collection' of Robert Haynes.] If we accept Haynes' theory regarding the genealogy and history of Bizen Shōami family, Momoyama period attribution would seem unlikely. I am leaning towards the early to mid 17th century.

Kyo school iron tsuba of round form decorated with an eight-plank bridge (yatsuhashi) and irises (kakitsubata) in openwork (sukashi).

Late Muromachi period, Tenbun era (early 16th centiry).

Dimensions: 80.0 x 77.2 x 4.1 mm.

The design alludes to the scene in 'Ise Monogatari', where Ariwara no Narihira being exiled from Kyoto to the Kanto region crossed the eight-plank bridge at Mikawa looking at the irises in bloom and composed a poem expressing his desire to return to Kyoto. A lot of tsuba have been produced with the similar design.
