Surely your house can't be the only one in the known world that doesn't have a canister of WD40 somewhere around?
Place the knife, as open as you can make it, on a piece of absorbent kitchen paper, then spray it lightly. Turn it over and do the other side.
Now just let it lie there for ten minutes or so.
Then start moving the tools one by one, let it lie another few minutes, and you'll find it's fine. Wipe the oil off very thoroughly with more absorbent paper, and you might have to do it again in half an hour or so, but basically, job done.
