Hi Dave,
I just bought one today so I'll give you my initial impressions:
Because of the dual steel liners it feels heavier than other FRN knives...maybe solid is a better word.
I've been carrying a CRKT Bladelock since Christmas so the Vesuvius feels light to me.
The appearance is very classy and tasteful and does'nt look like the other Spyderco FRNs. I've even had a few friends think it was micarta until they got a up-close look at it.
On the down-side, it is a little slick and slippery in the grip. At least more so than the volcano pattern knives.
The handle shape itself is very comfortable to me (except in reverse grip-- but I don't really use that grip anyway).
The blade: The blade-shape is the main feature that attracted me to this knife and so far I like it. The tip seems plenty strong and the cutting-edge of the blade extends almost to the handle itself (very little exposed tang).
The hole is rather large and easy to thumb open (I hate tiny little Spyder-holes).
The thumb-ramp is okay but the peak is very sharp, too sharp in fact.
The clip is changable to tip-up or tip-down but I would recommend tip-down because this knife opens EXTREMELY easy.
I will not simply fall open, but it takes very little pressure to open the blade. I understand the compression-lock so much better now and I can see the strength and cleverness of the design, but I can't get over how easy it opens.
I was surprised to discover that there is no ball-detent. The tang actually has a small cut-out that the lock-bar slips into when the blade is closed.
So I guess my only dislikes are: slick handle, sharp thumb-ramp peak, and my (perhaps unjustified) fear of it opening in my pocket.
I'll carry it everyday for awhile and see if it's the one true "EDC" that I've been searching for (though the CRKT Bladelock will be hard to beat. I love that knife but it's just alittle heavy).
Good luck,
Allen.
