as far as i am concerned, the 0300 is a knife that you can beat the snot out of and not worry about it. the 056x seems like more of a every day folder and 07x0 seem a little bit more like souped up kershaws. That is awesome, but not the same as the 0300. in short, if i am going to want to beat the living crud out of a knife, i go with the 0300. if i want it to excel at everything EDC and be a very fun knife, i go for the 056x or the 07x0.
