While in the local Wallmart, yesterday, I found an interesting Gerber item, at least I've never seen it before, called the EAB pocket knife. It is a small folder with a liner lock that uses heavy duty utility blades. At $10, not a bad choice for EDC or in a bag or pack. It is 5" long, just over an inch wide (66/64), 13/64 thick (21/64 at the top of the clip) and weighs 2.1 ounces. A five pack of the heavy duty blades cost $1.20 and weighs 0.8 ounces in the blister pack. Perhaps not a bad consideration since you have new/sharp blades readily available. Two "howevers" though, you need to loosen a small philips screw in order to change blades (many multi-tools have this small bit) and, in its out of the box iteration, you can't open it one handed (but you can open it with one hand and your teeth). All in all, it might be a viable choice for your pocket, the pocket clip could be a money clip as well, a small survivval kit or other.
