My initial impressions are that it is a very solidly made Buck 110, and that is a compliment. What I mean is that it is a classic folder with a very solid back lock, so don't be looking for anything fancy there, and that it's blade is a modified Bowie shape, just as the Buck 110's was.
But the Chinook's has a very much more pronounced swedge, not surprisingly, when you consider that it is a James Keating design. Keating is THE major proponent of the back cut in knife fighting, a technique that requires a pronounced swedge and very sharp point. It works best if the swedge is sharpened, but there are state laws about double-edged blades with which to contend. Of course, you can always sharpen the final 1/2 inch of the swedge, as the author of the review in "Tactical Knives" current issue suggests, but I say "Good Luck in such a reshaping project on a CPM440V blade!" I suspect that the point would do very well in a back cut as is, thank you, but perhaps Sal or James Keating might have something further to say in theis matter. Sal, I think that this suggestion needs some consideration from a safety point of view, as well.
The knife is one heavy duty dude, that I can tell you! Dual liners and a very thick blade make it heavy in the pocket as well. This is not a light weight carry like a Military or a StarMate. You can look up the hard statistics, but that is my subjective opinion.
The shape of edge is a cutting wonder! I have tried it on all kinds of softish things like cardboard, leather, paper, and cloth, and it cuts up a storm. I surely would not want anyone cutting at me with it! As the review in TK said, it makes a heck of a skinner.
I have tried holding the knife in all hand grips that I can think of and I have yet to find one where my hand would be pressing upon the lock release bar, however, this may vary for others, so I cannot answer that question for you. I suspect that it depends upon hand size.
Again, the only concern that I have registered to date has nothing to do with the knife but with a very public recommendation about a modification to it about which I have some doubts and concerning which I think Sal might have something to say.
