Mine is a Leatherman Micra, with pliers instead of scissors, 1.9 oz. I find I use the pliers more than anything else, mostly as a pot lifter but also for times when straps get pulled out of buckles. I am not very dextrous and have a hard time getting hold of a strap end that I've managed to push 1/16" through a buckle. The next most used item is the file, for my frequently splitting fingernails. The knife blade comes third. One of the tiniest screwdriver blades is just right for tightening the screws in my glasses. I wish I could remove all but that one and a "normal" sized one, though, to lighten up the knife a bit more and make it easier to find the one I want. I couldn't do any of this stuff with a razor blade. On the other hand, I'm trying to cut skin-out weight as much as possible.
Yes, it's harder to clean a fish with a 2" blade, but I've done it. I never was any good at filleting even with a proper knife! The 2" blade is also quite adequate for making frizz sticks to start a fire or for whittling a point on a stick in case I lose a tent stake. It certainly would be completely hopeless for dressing wild game or something of that sort or for cutting rope in a hurry (vitally important if you're working with horses). But I don't hunt and I haven't horse-packed for 50 years. If I'm taking out my grandkids and have to lift larger and heavier pots, I take a Leatherman Juice (next size up) or a separate pot lifter.
In my part of the country, cutting poles for a tent or boughs for a bough bed is very much a no-no. It's all "leave no trace" around here. So there's no need for a knife to do that.
