It's the "Sherman Tank" of Spydies! Man, this thing is robust! "Built like a tank" really does describe the construction of this folder from Spyderco. And, it feels that way in the hand. It's not a lightweight!
Action is VERY smooth, and the blade is SICK-SHARP! The liner lock is difficult to disengage, though. Very stiff and there's not a big cut-out access like the Sage has, for example.
With no further ado...
Close-up of CF - pretty much identical to the CF on the Sage 1.
