The 1796 spadroon was referred to by one officer as "the perfect encumbrance."

from what I can tell it looks like it would handle like a late 17th century transitional rapier but with a very simple smallword hilt. It might have some good kinetic "thwak" on someones temple but looks like its better suited to the thrust. Maybe not suited to battlefield conditions. Ive read some old references where it is recommended for the "gentleman" for civilian purposes. I see a lot of dipictions of using a hanging guard for the Spadroon, but the rest of the technique seems much like smallsword.
I remember that my my old 1786 Heavy Cav dress sword handled much the same way, A nice compact, double edged transitional rapier. Of course the spadroon is longer and single edged. So I guess I'm totally off topic now. lol.
