Back when MP3.com was cool and independent, and the Internet boom hadn't busted yet, I went to this MP3 Summit thing in San Diego. They gave everybody a big bag full of gimmes. From that bag, I still use the bag itself (it's rubberized, so it's good for wet gym clothes), an RCA Lyra 10-CD case, and an Adaptec CD wrapping opener. This is a customized gizmo with a protective plastic guard around an internal razor blade. When you press it on the size of a CD jewelbox, the plastic guard moves back just enough to expose the blade and let you make nice cuts through the shrinkwrapping and the stupid sticker across the top of the CD as well. Heaven only knows where you could find one of these, but it's a fantastic toy. Before I had that, I just used a pen knife (back when I had the knife on my keychain, when you could actually fly with a small knife in your pocket).
