With Pyrrha, my point is literally that she took a stabbing weapon (a spear) and made it also capable of slashing by making it double as a xiphos.

There were old, old styles of rapiers that people used for both stabbing and slashing, so while a rapier isn't the best for slashing, it can still be built to do such. It doesn't necessarily have to be amazing at it for it to help Weiss not be left with just an oversized needle if she runs out of Dust. The only thing questionable is that she rarely uses it for stabbing.
