I am going to love that piece of equipment. It is just great for having little ekstra trick for places where no weapons are allowed. You can leave your sword with grand gesture behind the door :D

But there are some questions about it. How are you going to get it off around your belt fast enough to use it in combat? And how do you prevent the scabbard just flying off from the sword?

I know that these issues are easily solvable just by adding a quick-release to belt and bladelock to scabbard. But then there must be someone keeping track, if the blade is locked or not. Nasty little surprise, if it happens to be locked when time calls quick bladework.
