Thanks guys.
I appreciate all the kind words!
To give some insight in to my thoughts behind it; I've always noticed Maul would hang his saber closer to the emitter. And like Korr said, it is more useful than the covertech knob, especially where the knobs are to be placed on the end of hilt (or right in the damn middle of it when configured in to a staff). I've also seen covertech kill keys done often as well. So my thoughts just naturally progressed.
I only put one d-ring kill key and not one on both sides because it's only necessary to have it from the one side. If I choose to separate it to a single wield. I'll put it on the one I want to carry. The weight of just a single hilt feels less strenuous on it. The full 21" Mauler has a nice weight to it and to be hanging like that for long periods would also put strain on the pin in the charge port. So luckily it's always displayed horizontally.
I also only put one on it because this was a test flight and I only had one spare d-ring and one spare kill key to attempt my idea with lol.
