Possibly seiryu’s sword, it has a guard on it but other than that it’s a fairly slender sword. Deepshadow is pretty easy to get and can be dyed if you don’t like the black. Diamond sword from omega is pretty slender and has a curved tip. Homura kai might work although it’s a bit jagged. Ala mhigan kilij is the kind of thing I’d think of when I think 1 handed sword with no shield but it’s more Middle Eastern style than Chinese.
