Description
Duǎnjiàn (短劍) literally means "short sword" where the word for sword, jiàn, specifically refers to a double-edged straightsword.
On today's antique market, duǎnjiàn are one of the most commonly encountered Chinese arms. Their small size and exotic appearance made them popular tourist curios that easily fit in the steamer trunks of the day, and they were brought back en masse. One of the main production centers of these was Canton, known today as Guangzhou.
Varieties
Duǎnjiàn come in a few main varieties. The most obvious distinction is that between sets of single duǎnjiàn and double swords, called shuāngjiàn (雙劍).
In terms of mounting styles, there are:
1. Fúshòu (福壽) style with stylized bats and longevity symbols.
Guards on the fúshòu are often en suite, with a longevity symbol and bats on the guard as well, but sometimes of Tāotiè (饕餮) form with a stylized monster without a lower jaw.

Less common is the heavy gilding and white parchment scabbard.

2. Kuíwén (夔紋) style with archaic kuī dragon patterns.
The kuíwén type is almost exclusively seen with Tāotiè (饕餮) guards. Usually one of the mounts has a salamander-like chīlóng (螭龍) or "rain dragon" on it, and often one of the mounts has the words Lóngquán (龍泉) as well, referring to the famous sword-making town in Zhejiang province. Their style being typical for Guangzhou, I believe the referral was mainly symbolic.
