Chicken sickles (鸡鐮) are a number of Chinese bladed weapons similar to the Hook sword and the Okinawan Kama. They can be used as a single or double weapon. It is considered the special weapon of the Xinyi Liuhe style.
Chicken Claw:
Jī Zhuǎ Lián (鸡爪鐮 - Chicken-Claw Sickle). The chicken-claw sickle was constructed from a chicken claw-like piece of metal, along with a spear head, on a length of stick. Its length was about 1.5 ft. The details of this weapon are unknown. This sickle is more similar in appearance to the Okinawan Kama, with the addition of a spear head.
Chicken Sabre:
Jī Dāo Lián (鸡刀鐮, Chicken-Saber Sickle) is a weapon that was also called the Kǔn Huā Yāo Zi, or "Binding Flower Waist Carry". The reason for this optional name is unknown. According to legend, this weapon was created by the founder of Xinyi, Ji Long Feng, and it became the special weapon of this style. It was made from metal and its length was about 2.5 Chi [32 inches]. This sickle is similar in appearance to the Hook sword and although it is named a Dao (saber), it is based on the double-edged sword (Jian). There are several variations of this weapon. All have the distinctive hook and chicken "spur" on the head, but the sword blade is sometimes shortened to a small metal pole-arm. It is used for close-quarters combat. One noted practitioner of the Chicken-Saber Sickles was Xinyi Liuhe Grandmaster Lu Songgao, one of the "Three Heroes from Zhoukou".
