Query: I'll be honest, I don't use all of the functions of this tool.

I only bought this because I wanted a replacement for my old bottle opener that was flat and fit in my wallet, so I haven't used most of the other functions of it. However, I moved a week ago and the sharp edge was great for cutting open my taped-up boxes. I've found myself using this more than ever as I'm unpacking. My family thought it was such a nifty little tool that I ordered three more for my relatives. Its so cheap, you can't beat the price.
