Greetings everyone. I've been a lurker on this forum for some time now and now I want to start participating.
I've often heard the terms yan mao dao 雁毛刀, liu ye dao 柳葉刀, pian dao 片刀 and niu wei dao 牛尾刀 used to describe types of Chinese sabres descended from the Turko-Mongol sabre. Where do these names come from? Are they mentioned in the er shi si shi 二十四史 or are they names out of Chinese martial arts lore?
The sabres were so-named based on how the shape of blade looks like.
For "
Yan Mao Dao 雁毛刀" (literally means " Wild Goose Tail-feather Sabre"), the name was derived because the blade was simply shaped like the feather tail of the wild goose (Yan = Wild Goose, Mao= Tail-Feather). This sabre is also known as "
Yan Ling Dao 雁翎刀".
Below show a Yan Mao Dao.

"Yan Mao Dao"
As for "Liu Ye Dao 柳叶刀" (literally means "willow leaf sabre"), it was called "Liu Ye" (willow leaf) simply because the blade was shaped like that of willow leaf.Below illustrates the Liu Ye Dao:


"Liu Ye Dao"
As for "Niu Wei Dao 牛尾刀" (literally means "cow's tail sabre"), it was called "niu wei" (cow's tail) simply because the blade was shaped like that of cow's tail. Below illustrates the Niu Wei Dao:
