If you're willing to spend the money, and want a beast of a knife, that's lighter than a Mora but with just as much utility, consider one of these.
Just got one of the Necker 2's myself and I gotta say, it's awesome.
With full scales in G10 it weighs about 1/2oz more than a Paracord Wrapped Izula, but that's for 3/4" longer blade, full convex grind, and comfy full scales.
Personally, I can't see the value in those ultra mini utility knives. I break the full sized utility knife blades constantly. Swiss army style knives are great for the multifunctional aspect when viewed as a whole with it's tools, but..
Well, some things just take an actual knife. If you're not interested in any sort of bushcrafting or anything, then I'd stick with that Kydex Straight Razor someone posted above, or the suggested duct tape wrapped utility blade.
Otherwise, eat the weight (2.25-2.75oz) and get a BR N/N2 or Esee Izula.
That's just me though.
