There are more than 1, weapons found in the Terracotta Warriors and Horses Pit. There are many kinds of weapons, such as ge, spear, sword, etc. These weapons are basically bronze, which are formed by casting and fine processing. The bronze sword unearthed from the pit of the terracotta warriors is very sharp, and its blade is polished. The polished traces are parallel, one by one, and there is no interlacing.
