The 311 is my favorite. I find myself using it more that any other blade, because it's the one I'm always carrying. The full sized handle fits my mitts (XL) and the blade is perfect for precise,close in work. And I have no worries about breaking that little beast.
I like it so much that I even got a scout carry Rainwalker sheath for it.

Remember this: Everytime I blink, you disappear.
