Lightsabers aren't things you can easily fiddle around with and create. That is why they take so long for a Jedi to create. At most, you could make one that last for a thousand years in a month or two. The reason why is that it involves concentration of the force. Not physical power, or tool creation.
So, everyone, don't try fiddling around with the idea of a lightsaber just coming into your palms in a matter of days. At least it takes a week to construct one by the hands of a Jedi.
It is physically impossible for a normal being to create one.
Now, it is possible that you can probably get an one of the crystals that are needed to create one, but past that isn't going to happen.
Anyways...I just wanted to drop the knowledge, if Graysith feels otherwise, I'm sorry I created a mishap. Just pointing out something for RPers.
