I just might be the only vote for the Rodent 4! I hate to throw a wrench in the works guys, but I honestly like the Rodent 4 more than the Ratmandu! When I first saw the new Rodent series ergonomics, I was very skeptical based on the pictures. I got my hands on a Rodent 9 and Rodent 4, and I LOVE them both. The handle bumps might not suite others' hands very well, but my mitt fits like a glove on these babies. The bump allows TWO fingers on either side at all times, thus you have complete control choked up on the blade, gripping the entire handle, and choked back on the blade while chopping. Plus the R4 is noticeably lighter than the Ratmandu. Makes a world of difference if you carry your knife on your belt while hiking. LAST comment: the Rodent 4 arrived sharper than any other Swamp Rat knife I have ordered :thumbup: Thin stock SR-101 and the new ultra convex bevel make for a sharp piece of steel! I will do something semi-productive with my Rodent 4 (no promises though) and post some pictures of the ergos in action. After all, having a safe queen Swamp Rat should be illegal
