- In early works, Ikkanshi Tadatsuna used the same signature as his father’s. It’s kind of hard to tell the differences between their swords as their signatures slightly differ in the strokes of the Kanji characters “栗” and “綱”.
- His works with the carving often have the inscription of “Hori-dosaku(彫同作)” which means the carving is done by himself.
- He had 3 signatures;Awataguchi Oumi-kami Tadatsuna(粟田口近江守忠綱), Awataguchi Ikkanshi Tadatsuna(粟田口一竿子忠綱), Ikkanshi Tadatsuna (一竿子忠綱).
- The smith’s father is considered to have been a descendant from Awataguchi Kunitsuna(粟田口国綱).
