Qi Dao is a form of currency cast by Qi State. This kind of currency is famous for its heavy and exquisite appearance, which usually has basic forms such as sharp point, curved back and concave edge. The end of the knife is often a ring, and the blade may be engraved with words or decorative patterns.

Qi Dao, as a currency, circulates in Qi State and serves as a medium of transaction. It is usually made of bronze or iron and has a certain weight and value. These knife coins may be engraved with inscriptions on the blade body, recording the coin maker, casting place, year number or other related information. These inscriptions not only provide proof of currency circulation, but also provide valuable information for historical researchers.

The shape and ornamentation of Qi Dao coins may change to some extent, but they are all based on the shape of Dao and are well-made. The artistic style and craft of these knife coins reflected the cultural level and coin-making technology of Qi State at that time.
