I'm a lucky guy; I drive by the SFO on my way to and from work.
Got to play with the Vesuvius and the G10 Lum yesterday.
I have to be honest: I didn't love the Vesuvius. The handle is FRN (we call that Zytel in my parts) with a shell inlay. I kinda expected G10. The blade shape is very cool, and the compression lock is better than a liner lock, but it still suffers from the liner lock's problem keeping the blade in the handle. You know, 3 degrees of rotation and the blade's out. A lockback and an Axis lock are safer.
Anyway, my major gripe was the Zytel.
The G10 Lum is nice, but you lose some mystique in that knife when you lose the titanium scales.
