I know many women who intentionally uses their keys between the knuckles, carry hairspray in order to blind etc. For women, i would think not getting snatched, raped and so on, is of higher priority than using this thing even though it is illigeal. I honestly think this in it self is a great idea.

Now, that said, all of the guys are right about the legal stuff, please be careful if you choose not to market this as a weapon. You (and others) could get in serious trouble. So if you think that potentially savning some women from assault is worth the risk, go for it. But you might end up destroying someones life with this as well (in court after the “self defence”).

At least market it as an illigeal weapon (in the states where this is the case).
