General reply to everyone:
Yeah, the hilt are quite heavy. My next ones are supposed to be a bit less heavy, or at least that is what I gather from reviews of different SF sabers.
While the weighing down is of course not so pretty aesthetically, I could live with that, as long as there wasn't the threat of it falling off!
I suspect it might be because my covertech is from Hasbro, and the real one might be stronger.
But even so, a belt loop would feel a lot lot safer. Then it simply can't fall off unless your whole belts fall of.
If anyone didn't understand what I mean by beltloop, I have attached an image. Instead of a camera case or whatever that is, it would just be the cover tech system of course.
The idea of clipping the clip over something thicker - pants and belt for instance as IosefKoranison does - is good, but doesn't work if you use it on an obi/waist belt.
I don't think D-ring or covertech makes a huge difference, if both are clipped on. It of course distributes the weight a bit differently if it hangs from a D than a knob, but not a whole lot.
