The first time he saw my small sebenza, my partner was surprised - didn't realize that sometimes things need to be cut. Curiously, he was similarly surprised when I brought my DRILL to work. The reason I mention it is that sometimes you have to think about context. My partner was never in boyscouts, never in the military, and has never fixed or built anything. However, he is a very accomplished physician (I guess he might have used a scalpel in medical school). Now that I have educated him a bit, he seems to understand tools and knives a lot better. That is, I'm not sure he would ever carry a knife (or drill) himself, but he sees that they are just tools (e.g. sledge hammers can be used to kill, too). Thats fine, I probably won't ever own a sledge hammer, but they don't freak me out either. All I want is for people to learn that a reasonably sized knife is not a freakish threat to their safety (especially when in the pocket of a mild mannered country pediatrician such as myself).
