Back in the days of the mid-70's I used to do sword and dagger costume duels with sharp epee and dagger (and a well practiced opponent ) Interesting to note that many of the 'buckler' moves were replicated with the dagger. You could also have interesting costume fights with cloak and dagger - against someone with a rapier.
