The Native Chief provides more self-defense point.
The Chinook has as much point, but it doesn't appear so to most observers.
Both the Chinook and the Native Chief have more point than the Manix.
Yes, I know the Manix has a point, but not as acute a point as either the Native Chief nor the Chinook.
If one put a swedge on the Manix blade, gave the blade a higher aspect ratio, and raised the point so that it didn't drop so far below the center line of the grip, he would have a Native Chief.
I don't care for the Manix because it doesn't have enough point.
Put some point on the Manix, make the blade profile leaner, and raise the point in reference to the center line of the grip, and I'll buy it.
The Chinook has both point and belly...lots of point and belly.
The point intersects the center line of the grip, and I think the blade of the Chinook has a longer edge, by virtue of its long belly, than almost any other Spyderco knife.

I just searched Spyderco's site for a Chinook and didn't find it listed.
Has Spyderco discontinued the Chinook?
Unbelievable.
I consider the Chinook II (hollowground) the finest all around, self-defense folder ever offered to the American public, at any price.
