It sounds like it could certainly be possible, but I don't know abou making them visible. It would be a good reason for an adversary to be motivated to lop off your limbs to disarm you. If you had some, I'd put it under your clothes where there's a less likely chance it could be seen, and not on a limb where it could be easily grappled and cut off, such as a hand or arm. I'd also save it as a trump card, maybe even use it while holding a book (any book) to make it appear you are better armed than you are.
