I enjoy reading 2nd Amendment articles, and this paper by Glenn Reynolds of Instapundit is a good one covering recent court cases and the expansion of 2A to things like stun guns (though he doesn't go into knives).

In a nutshell: Momentum is mostly on our side, if we can just keep or enhance the originalist leanings of the Supreme Court.
