Zi Collection, Upper Volume, Page 4, Entry 01 Radical: Knife (dāo) Pronounced xuàn (falling tone) From the "Guangyun" and "Jiyun," it is pronounced huǎn quǎn (falling tone), the same as "xuàn." The "Yupian" explains it as an ornament on a knife sheath. The "Jiyun" states it was originally written as 鞙. Detailed explanations can be found in the commentary for the character 鞙 later.
