I also tried a few Ganzo knives, and have kept 1, the model that looks like the Spyderco Paramilitary 2, but with their version of Benchmade's Axis lock. I have since gotten a left handed PM2, but until then i had to switch hands to close it with my right hand.
I still like the Ganzo. Being 440c, it sharpens quickly which means you don't have to hold your concentration as long. Ganzos are just a bit heavier and thicker than the models they are based on, but not grossly so. Funny thing is, I've got enough knives that I switch between, even the Ganzo would probably last my whole life before it is unusable from over sharpening.
Now it's time to get into sharpening. Got a bench stone and a guided sharpener for when you get fed up?
