The weight is as advertised at 3.9oz so it's light, IMO. Weight with sheath is 6.4oz so it would hardly be noticed if carrying. It is just a bit butt heavy.
The full flat grind is what really sold me on this knife as there is something about the blade aesthetic that really calls to me. I would have bought the original GMF2 but was pleased to see the next gen knife was full flat grind and M390.
And I would think that full flat grind helps it cut the way it does for a fairly thick and not-so-tall blade. When I picked up the Ti Orso in the background, I was scared it wouldn't cut well since it's so thick but it immediately became my favorite knife to EDC because it cuts so well. And the GMF2 cuts just as well. I wouldn't call it a "slicer" but I don't need it to be either. I bought it to cut up bait and clean fish that I would be eating whole. And while they did crown the spine they left just enough of an edge that it cleans off scales. I wouldn't use it to fillet a fish, but it will cut through fish bone so making steaks is not difficult at all as long as the fish ain't no fatty.
About the only thing that isn't useful for me is the jimping almost halfway down the blade. I would have loved that jimping right at the ricasso. I imagine they put it where they put it for wood working but I'm a city boy growing sea legs so I doubt I'll ever use the jimping.
Overall, I am thoroughly pleased with the knife and so are my fishing friends.
