It's really a very beautiful piece, been playing with it for an hour now. Razor sharp out of the box, not quite hair popping (with no pressure) but it does shave hair. I'm not normally a fan of lockbacks because of the resistance to opening, hence why I previous bought a Sage 1 instead of a Caly 3, but the Caly 3 Damascus is much smoother than my Delica or Centofante 3, very easy to open.
I don't mind the pivot construction as it keeps the scales very clean and elegant. There is a tiny amount of side-to-side blade play if I really pull the blade around, but basically all knives have this (even Hinderers that I've handled)
My few gripes:
1) I wish they would have used ZDP-189 for the core and not VG-10. Not that this is going to be a heavy-use knife, but we know they can do ZDP-189 bonding so I'm not sure why they went with VG-10 here.
2) The back of the tang that rides the lock mechanism while opening is dark, not from rust but I guess from the acid bath? There is a very tiny bit of a gritty feeling while opening. Not like on a cheap knife, but a very almost unnoticeable amount. I'm sure this will improve with time. Still I would think covering up the tang portion of the blade during the acid bath to reveal the damascus would have been smarter to ensure a completely smooth mechanism.
