On another side note, you should see the teachers in the teacher's lounge when I use my Case 62109 Mini-Copperhead to peal an apple at lunch. Some of them "eye" me with extreme caution!

I'm also a teacher who carries a Peanut at work. At my current school, nobody gives me a second glance. At my previous school, I once took out my pinkie finger-sized Peanut to poke holes in a package before microwaving. Another teacher said I reminded her of Norman Bates from "Psycho." I pointed out that Norman Bates used a great big kitchen knife . . . Like the one sitting on the counter that everyone else had been using for things, but didn't bother her for some reason.
