I like the half-serrated/half regular edge blade so you get the best of both worlds (serrated suck for spreading peanut butter). If I need a bigger, more functional tool, I like my Kershaw multi-tool. It's big and heavy but the features I've used it most for doing field repairs on things like ski bindings, tent poles and such is the locking pliers (vicegripe)... Works as a wrench most of the time.
