All I've done is play with the knife in a shop, but I second that about the handle. I was shocked that it could be that comfortable; frankly it looks like an ergonomic nightmare but it fills the palm beautifully, which I rarely find for hands my size. The finger area is as flat as it looks but you hardly notice it because there's such an extreme angle to rest your index finger against.
The lock I'm not so sure about. Was I right to figure you have to push the button and open the blade at the same time? That was the only way I could open it. Seemed like a slow, inconvenient, two handed way to open a knife, but I've since wondered if there isn't a "trick" I didn't know. The guy at the store didn't know--I got the new guy!
Anybody have any experience with the Auto? I'd like one for my dad; he couldn't carry it but he loves those cheap Mexican switchblades and I think he'd have a stroke if he opened a "real" auto next Christmas.
