In my career, it's sheet metal edges, and poorly cut nylon ties. Fun fact, in the winter, an angle cut zip tie cuts like a razor. Another fun one is, again, in winter, you don't need to do anything. Just be cold and make a fist. Your skin will split on its own. Speaking of slivers, how come a sliver of ⅛" -⅜" feels like you were impaled. Then you can cut all the flesh around it to remove it, but none of that will hurt as bad as that hair of a sliver?
Brake cleaner is the fastest path to finding cuts and slivers that I know of.
