Ok, so I'm heavily leaning towards a Caly 3 with the CF & ZDP-189 as my next purchase. One hot-button issue with me, however, is one-handed operation. I must be able to easily open and close the knife with one hand. I've owned the original Manix before, which was also a lockback, but it was easy to close it with one hand with the finger choil that it offered. So my question is to anyone who has played a bit with a Caly 3 and an original Manix, can you close the Caly in the same manner as you could that Manix?
