I'm guessing the 9-11 is just two inches longer than the 7-11, which I think is a GREAT knife!!! The BattleRat and 9-11 should be close to the same knife, which is a good thing as I think my BattleRats are great as well. And don't overlook the Rodent-9 as well! <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
