Mine is a keeper. I've read multiple reports of people being "less than enthusiastic" about the handle design. I have medium/chubby hands and the handle design inspires confidence. That being said, I got a terrific deal on mine because its previous owner did not like the handles. To me, the Rodent 9 and 911 look like the same blade with different handles.
Either way, you get a huge piece of SR 101 steel to beat up for a lifetime. Try to hold the Rodent 9 before you buy as it may take a while to resell. The 911 has the res-c, which I dont recall people not liking the way it felt in thier hand. YMMV
