I'd buy the lightweight Manix 2 if it wasn't pin construction in a heart beat. I love my normal Manix 2, but having it light weight would be really nice! I just don't like the idea of pin construction.
Also, the hollow grind isn't an issue. I reprofiled the factory bevel on the sharpmaker to the recommended settings and it slides right through tough materials with ease. It was a little tough to do that with the factory edge, but once you thin out that bevel a bit it comes to life. Also, with that hollow grind, it's still nice and thick at the tip. Nice work knife.
