What is the name of a weapon with a slightly curved tip?

Euphorbia is a lady's knife. The blade is so curved that even the handle will bend with it. It is estimated that the handle of Madam's Dao is curved, but it must be a wild Taidao anyway. Tatsu Yamashiro is a kind of knife, also called sword, with moderate radian and straight handle. The difference between Daqi and Tatsu Yamashiro lies in the different position of the inscription, which is outward, so Taidao and Daodao are attached in different ways. The blade of Taidao is downward when sticking and upward when sticking.
