That sounds logic since the base of the blade has a wider radius than the tip.

That said, if I had to choose between a rapier and a Jian, I would pick the Chinese one. It retains the focus on speed and stabbing but adds the possibility to cut, the steel is forged to be flexible so it can bend when it goes in between the joints of armor. They also come in different lenghts and are meant to be as light as possible.
