I also carry a knife to cut my salami (and more importantly open the vacuum sealed package), but it is a frivolous use really. I was just playing devil's advocate as I know many people feel deeply attached to their knives. I don't think my knife is even sharp enough to cut bandages etc...however a Leatherman Juice is a different beast as it has many other tools on it. In this respect I DO sometimes carry a small pair of scissors, a good set of tweezers and a razor blade, but I have not 'needed' a knife for as long as I've been backpacking. I have also never needed Needlenose Pliers, Wire Cutters, Hard-Wire Cutters, Extra-Small, Small, and Med/Lrg Screwdrivers, Phillips Screwdriver, Lanyard Attachment, Can/Bottle Opener, Corkscrew, Fish Scaler, or any of the other myriad attachments found on many multi-tools (at least not on the trail).
I agree that there are far worse weight:cost savings ratios occurring here at BPL than $47 for 8 oz. That's a real bargain!
