One advantage of a single bladed weapon is the more forgiving blocking potential. No double edge sword self injury and all that.

Mmhmm, you could also do half swording esque things with little to no worry of injury, I remember hearing about a bunch of men with Scimitars attacking a Redcoat line as they wandered through a town, the swordsmen basically ran up close and pushed their own blades into the Redcoats with their free hand, rather than swinging and slashing like they are portrayed as being used historically. It might have been a specific method used for tight quarters where you don't wish to injure nearby people, as they were fighting in their city, but interesting none the less.

Every sword has its advantage and disadvantage I suppose.
