These are the ones I'm referring to (http://www.dlsports.com/knife_dangers.html). For the record, the first time I saw them was when a friend of mine, and a fellow senior, who is a cardiac surgeon, sent them around to us, which included the stories for the injuries, and the fact that, despite the appearances, these injuries were really superficial, rather than genuinely life-threatening. Still damn scary, but this is the difference between slashing attacks and stabbing ones.
Yup, those're the ones.
