Curious why the Kershaw Avalanche has been left out of this discussion so far. I have one, G10 scales, S60V blade, nice size, deep carry; only about 1/4 inch of the scales sit above the clip. It doesn't have a safety, 3 inch blade, 4 1/2 inches closed, the thing is built like a tank.
I also have a Wild Weasel, and although I like it, it seems a little flimsy compared to the Ken Onion Avalanche...
By the way, you can close the Wild Weasel using the tip of your thumb on the lock, but the lock on the Avalanche is so strong and so well protected you have to use your thumbNAIL to move the liner lock to close it up.
