Yoshihiro's one signed blade is a with a large two-character signature cut in a thick chisel, handed down in the Ikeda family, and of it the published sources write that 「在銘作はこの一口だけであり、資料的価値はすこぶる高い」. They cite the entry in the shogunate's official chronicle for the fifteenth day of the fourth month of Kyoho 2 (1717), recording a sword by Yoshihiro given to Ikeda Tsugumasa, and take the to be the blade the eighth shogun Yoshimune bestowed on Tsugumasa when he succeeded to the headship of the house; it carries an of the same year by Kochu. Yoshihiro belongs to the school of , which appeared in the early period and, leaving behind the classical Kyushu manner, established a style the published sources describe as 「地刃が明るく冴えて垢抜けした作風」. He is said to have been the son of O- or one of his pupils, with a son, Kunihiro, and the record works dated Shohei 22 and 23 (1367 and 1368).
The published sources set him within a large following. Among the pupils and line of O- active in the period, signed smiths include Yasuyoshi, Hiroyuki, Yukihiro, Kunihiro, Hiroyasu, Yoshisada, Yoshihiro and Hiroyoshi, yet nearly all of their signed work is and , because the of the age were great blades of over three that were later shortened into . The smiths were close in skill and their styles differ little, so that 「一々鑑別することは困難である」. What they share is a forging of flowing with , and a temper described as 「湾れを主調として、互の目や丁子を交え、砂流しや金筋がかかり、匂口が冴えて沸えつき、荒沸交り、帽子が乱込んで突き上げて尖る」, a -based with and , and , a clear with and some , and a that runs in and rises to a point.
His blades follow this pattern. The forging is or , flowing in places and mixed with , tightly packed or tending to stand, with thick and fine, entering, and on two blades a faint . The temper is set on : on the signed a very shallow with frequent small in the upper half and and in the lower; elsewhere a with and , or a shallow enclosing and , with and , and , and adhering well. The runs in and rises to a pointed return, at times swept with .
The attributed show the full shape. Greatly shortened, they are wide with a shallow and an , and of one the published sources write that it 「時代の特色を示し、地刃に同派の特長が濃い」. The broadest of them, designated in 2018, has little taper and a thick ; its is a -laden strongly coloured by , rich in activity within the and along its edge, its rising to a point, and the published sources call it 「迫力ある豪壮な作風が顕現された同工極めの逸品」. It comes with a late in black ishime lacquer with scattered -gai. Another , its planed thin, looks at first glance like a and has a tsuchi-otoshi-style on the .
Yoshihiro has four designated works on record: two , the signed Ikeda and an attributed , and two , both attributed. Fujishiro ranks him Jo-jo , and the Toko Taikan rates him at 600. The provenance on record is the Ikeda family and Ikeda Tsugumasa, and the signed is in private hands.
