Cliff:
Jim has stated that the knife was designed to be used to "harrass" the aggressor, to "pick" at them with the backcutting motion of the big clip point Bowies, to get them to desist their aggression.
He is a big believer in the enlightened part of bladecraft, and does not agree and actually detests the "dark" side of the knife where one uses it as a means to kill.
It will take full bckcuts structurally but as the clip is not sharpened, the backcutting is not going to be as effective as a bigger blade whose clip had been sharpened and consequently the point is like a needle which really penetrates easily.
Compared to the Millie: It slices very very well. I think the Millie may be a tad better for slicing [ subjective ] based on it's flatr ground blade geometry ]. The Millie is known to be a great slice and dicer to begin with, one of thebest all around commercially available probably.
The Chinook is certainly very good as well at slicing, but probably not as much as the Millie in the final analysis. Then of course there is the question of the ultimate strength of the locking systems as well where the Chinook obviously shines.
