No, not really. Whipswords are fucking awful weapons. That's a fact.
For that matter, I actually know how blades fucking work. I actually research my shit, and I can tell you right off that a whip sword is not a very effective weapon for killing people. Or for fighting in general. It can't really defend, not without you entering into a freaking lengthy flurry of blows. And then all it takes is one guy willing to get a rather nasty long wound and your entire defense is interrupted and you're dead meat. Or someone smart puts a long stick in the way and the same thing happens. This long stick is known as a spear. It is the reason why whip swords don't work. They can't stab, they can't really slash, and the second that someone gets in their way, they're useless. Are they fucking awesome looking? Yes. Are they pretty much a giant 'KILL ME I AM STUPID' sign? Yes.
