I don't mind weight until I start getting into fixed blades. Once I get into the 4"+ area, then start asking myself what is this piece if kit really for.
My carry rotates a bit depending on what I feel the need is. There are some days that I carry a full size folder or fairly heavy OTF and a Leatherman Supertool on my belt. Most days at work I have been carrying the very lightweight BM Shootout with a Vic Camper riding in my other pocket. That set up literally weighs half as much. Today being a holiday, I'm bumming around the house with just a large Inkosi. Nothing going on. Nothing to fix, so just a nice solid pocket knife for general chores that pop up.
I think weight is relative based on need. I'm a contractor and having a knife and a tool seems to come in handy for my day to day. If I were someone who worked in an office, a simple slipjoint on small Sebenza would be more than adequate. While I don't think I will ever be a guy who tries to whittle down what I carry, I do shake my head a bit when it comes to those who arent first responders that EDC a folder, a fixed blade, a multitool, pistol, 4 magazines, a belt cutter, monkey fist impact tool, back up revolver, 3 speed loaders, iPhone, money clip, their cousin Jeff, and a single key fob.
I try to pack what I need for work: I will probably need to cut something, I will probably need to fix something, I will certainly need to get into my truck, I will certainly need to get into my office, I will need to purchase something, I will certainly (sadly) need to make and take calls. So, folder or OTF, multitool or SAK, truck keys/office building keys (which is a tangle of at least 6 metal keys), wallet, stupid annoying phone. More than that, and I need a good reason. All of it fits in the pocket of my jeans/on my leather belt.
