Get The Point?
They call this concept FemDefence (sic), and it is intended as a final protection against unwanted intercourse, aka rape. It is designed along the lines of a tampon with a springloaded needle at one end. Reminds me of stories from the Vietnam war where VC women would allegedly insert things like razor blades to catch unwary GIs. I suppose the string is to facilitate removal, though I it might be how the thing is triggered. To me, the string looks like a fuse. Fortunately, the whole idea is still on the drawing board. Pity the woman who puts one of these in backwards!
