Same here. Have a drawer load of folders and fixed blade knives.
What I carry most is a snap blade Utility/box knife. Plastic body, push out blade, bought at most hardware or Dollar stores. Buy a couple at a time and use them for everything from cleaning battery terminals to flattening boxes they work well, are feather light and I can take them into Canada or just buy a new one there for a buck or two.
But when there's work to be done I reach for my Leatherman Wave II.
