Thanks for the post. Don't tell aardwolfe we're still talking about kknives; it seems to set him off. ;-)

I don't go to rock concerts a lot, but a couple of years ago at one I was accosted by a drunk- got tired of his attempts to manhandle me, put him in an arm lock, but when I finally released him he just kept coming, shoving and shouting. I didn't strike him, though I thought of it... didn't respond, just stared in his eyes, waiting to see if he was going to escalate or back down. After a few shoves and some shouting he went away. I was carrying a knife at the time, but of course it never came to mind for this sort of thing. Sort of spoiled the evening, though.

I like Bill Harsey designs a lot- he and I clearly share some values with regard to knives.

You're right about the blade lengths; though I've seen some sellers list the Air Frame as 4" and the Air Ranger as 3.5", according to the Gerber site they're much closer than that.

I haven't seen an Air Ranger in person, and it took awhile to find a picture of one. I have to say that it doesn't really look that much thinner- probably one of those things you just have to check out in person, I guess.

What's that second knob on the handle near the hinge? I thought the Air Frame was a liner lock as well?
Here's the Air Ranger II you're describing:





and the Air Frame I'm describing:
