Generally I go at least a week before I find a use for a knife. I am very interested in them and even have bought a few nice ones int he past few months, but I just don't see myself spending much more on something I hardly see myself using. I'm not gonna go out of my way to find uses for em just so I can have more stuff in my pockets and go through more hassle at work, airports, with cops etc. At work I use a blade numerous times, but I have a box cutter they gave me that works great for the tasks I do there. If it wasn't for that job though, I'd have very little reason to ever have a pocket knife on me, which is why I don't really have an EDC, just a small folder I bring with me if I'm going somewhere It hink I might need it. Generally though, I end up not needing it at all and it only weighs me down.
