Park Tool SR-18.2 chain whip
Who rides a track bike and doesn't own a proper chain whip? Friggin' kooks, that's who.
Don't be a friggin' kook.
Pro tip: If you ever break the little pin holding the long chain to the handle, it's very easy to fix. When you're finished saying a bunch of cuss words, just reattach the chain using any 1/8" master link.
