Without a doubt, that NMFBM is a beast and a half. Some folks don't take into account the mass of their favorite chopper...me included. I have purchased knives that I knew would be a tad on the heavy side for real sustained work in the field. I suppose that is reflected in my choice of the Basic 9 when I exit the real world for a hunting trip. I do not feel tired when using that blade. I can pack the Basic 9 and not worry about excessive weight. It is fair to say that we have scant idea of how a knife will feel until we heft the tool.
And then we have the 1311. It is one of those knives that can be used for quite a while without suffering the pains of fatigue, and it works very well in the light machete category. As mentioned previously, I like the Ontario machete when extra reach is on the menu.
Enter the "cruise ship" Forsaken Mistress. Wonder how she will feel in the mit? I know one thing: she looks breath arresting.
