I've been carryin' a Chinook I since mid August. Just got it broken in about two weeks ago, to where it opens reasonably quickly and smoothly. As it sits, I'd say it opens pretty smoothly, but it was a helluva long break in period. One thing I've considered for it, is having a reverse grip kydex sheath made for it. (Reminiscent of the Pocket Hobbit) Then I know for a fact it'd be greased lightning, and I personally like the way it feels reverse grip.
If you like your "tactical" folders to be KISS simple and hellbent for stout, they're definitely worth a look. It takes a wicked edge, holds it forever, and the CPM 440V blade is not at all brittle like other blades I've had of the same steel. Inspite of the horror stories I've heard about strong men beginning sharpening 440V with strong healthy wrists, and ending the sharpening session with Carpal Tunnel, Tendonitis, and Arthritis, I don't find it to be that darn bad of a knife to sharpen. Other night I whittled my son a toy boat out of a 2X4 for about six hours with it. it had j-u-u-u-u-u-st lost it's shaving edge by the time I was done, which is the most impressive performance I've ever had from a knife. I had it right back to arm hair flying sharp within two or three minutes.
Also, don't let the blade profile fool ya'. It's not at all weak for thrusting. inspite of the dramatic curve, the point is dead center, and stouter than most knife tips. A bit too stout for my tastes, truth be known.
All that being said, I carry it more for general purpose knockin' around than any sort of tactical use, but if yer tastes lean that way, I'm sure either model Chinook'll do ya' just fine.
I usually carry a full sized bowie knife or a revolver daily, and the Chinook does become a bit of a load when coupled with either. For a primary carry, someone who carries a different load, or is just plain of a stouter heart than lil' ole me it'll do just fine though.
