I'm sure a knifeless multitool would be great in an airport, but on college campuses (at least on the three I frequent), there is nothing wrong with having knives. At my school specifically, the only knives that are outlawed are ones considered to be "dangerous weapons" in my state. That means no autos, no double-edged knives, no folding knives that can be draw into a locked position (a waved knife could fall into this catagory), and of course several other restrictions, but none that apply to any knives I would ever carry. However, there is no restriction on "normal" folding knives, multitools, or technically even fixed blades of any length.
