The problem I had with both of my 0550s is the fact that it was SO overbuilt, it just didn't appeal to me. However, it was a great knife for what you can get them on the exchange for. 3.5 inches of hinderer designed solid brick of a knife that can handle anything you throw at it for $150 or less?? No brainer in my mind. I EDC a Sebenza 25 and started thinking that was all I needed. I was into thinner knives I guess and that is why I traded the 0550. I just recently picked up an 0561 and for the size of that thing, it is VERY slim and "carryable". It's funny how my opinion changes, I am now thinking about getting rid of my military because I have the 0561 and picking up another XM-18. I had one of those at one point and traded it for the Sebenza 25. I think the moral of the story is, get a 0550 and a 0350, if you don't like one of them, sell it and then you will know for sure. Your tastes may change, if you are anything like me, they will change often. Good luck!
