I recently purchased an RTAKII and am very happy with it. However, like almost everyone else that reviews this knife, I don't like the sheath. It's flimsy and seems like it wont hold up (though I have no problems, yet). I have a couple Spec-Ops sheaths and these are excellent. But they don't make one for 10-11" blades. Anyone know where I can get one? (I don't want leather)
