All this talk of handing untrained people a razor sharp, double edged sword made me think of the ex-GF in college that I've mentioned before, who kept cutting herself with my kitchen knives, simply out of clumsiness and poor knife handling skills.
She also had an appalling lack of safety practices (when she cut my buddy on the shoulder, by tapping him with the tip of my Chef's knife to get his attention), and appeared to enjoy the alarm she caused when gesturing with my razor sharp 9" Chef's knife, waving it around while talking in the small kitchen in the apartment (oh, and found our reactions amusing when she was doing the same thing with a loaded CO2 BB gun).
Thinking about the K18 in her hands literally sent a shiver down my spine.
