I just got a ESEE-6 and am loving it. It's a great knife, I had a 5' Ka-Bar and it was just not stout enough for my taste. Now that I have the 6 with the Molle back and am wearing it on a Molle belt at my 4 o'clock, I'm thinking it's just a bit big for when I sit down/take a knee or am running. Is the 4 a better choise for a good utility blade for a Mill/Utility purpose or worst case a fighter? I really wish they did a 4 with the glass breaker, I think that would be the perfect knife for me. I have an Izula for small stuff and just want something bigger to handle anything else that may come along.
