My E.D.C., while working in education, was the smallest Swiss Army knife manufactured for retail sale. Only in a Swiss minature museum, might there be a smaller "army" knife than the one I depended on for daily duty. My E.D.C. had all the tools needed to survive in a public school classroom. There was a screwdriver/nail file combo blade, a one inch Valyrian steel knife blade, a plastic toothpick that fit ergonomically into the handle and a tiny pair of scissors. These scissors were so small, that they were exempt from the "running with scissors" rule. The knife looked so innocuous, I was able to walk it past courthouse and cruise ship security by placing it in the plastic tub with coins and keys...no questions asked. Only my students got wide-eyed when I whipped out this military grade multipurpose tool to open a box of Junior Scholastic books, snipped off a wayward beard hair, or zipped open an envelope packed with payola.
