As a conversation unfolds among teenagers on an Internet message board, it rapidly becomes evident that this is not idle electronic chatter. One youngster poses a question that, to an outsider, seems shocking: "Does anyone know how to cut deep without having it sting and bleed too much?" An answer quickly appears: "I use box cutter blades. You have to pull the skin really tight and press the blade down really hard." Another response advises that a quick swipe of a blade against skin "doesn't hurt and there is blood galore." The questioner seems satisfied: "Okay, I'll get a Stanley blade 'cause I hear that it will cut right to the bone with no hassle. But ... I won't cut that deep."
