Sage Ti: 3.4 oz
Sage CF: 3.2 oz
They are both very nice. I just received the Ti one and had the CF one. I prefer the CF version, but that is probably just me.
I am left-handed and the Ti one is not as easy for me to open as the CF. The surface is not as grippy on the Ti. However, I have not reversed the clip which would probably make it easier to open for me.
They both lock up solid and otherwise they are the same. I do not feel anyh real difference in thickness or weight.
