Does anyone have a Darksaber?

Yeah. Notice how he's hitting it flat on the edge. That would make it more stable.

Take a twack at the side and it'll snap at the base in one, two hits.

There have been, to date, no flat plastic blades that can be duelled with.

Then it's not really meant for dueling if it can't take a whack on the side. Why say it is for dueling when it is not then?

Still though you'd need to change the hilt as it is too rectangular and needs to be round

People have been trying to pass the "duelling Darksaber" blade scam for a while now. The best quality ones can take, at most, a handful of strikes before shattering, snapping, or splintering. But before people can disprove them, people buy them. And that's why people claim for them to be 'duel worthy'. Its quick money.

I have not heard anyone say it's a scam or seen videos showing that but then, never bought one or knew others of using it. Guess I would not be surprised though. I would like it if someone demonstrated it anyway just to show how tough it actually is. A shame because a dueling darksaber would be nice.
