I had a "hard use" phase, but my inabilitybto carry just one knife put that to rest. When you regularly carry 2-4 pocket knives, any thing over 3 oz quickly adds up to be a burden. I typically shoot for a 2.5 oz or so primary EDC, with a sub 2 oz backup, but occasionaly go over that, especially if it has an alternative carry method (my current team is a leaf blade G-10 UKPK in a neck sheath, and a drop point g-10 UKPK clipped to my right front pocket). Neck/belt sheath carry doesn't feel like a weight burden at all.
