Despite my praises, I have found some things I would call falts with the Chinook. The point is a bit delicate, and might not sustain real abuse, but its not designed to be abused in prying type work, so I won't take issue. I am a bit dissapointed with the knifes lack of versatility however. Mine has a single clip mount, for tip down, right hand carry. Personally, i like tip up. Not a big issue, but its how i personnaly feel comfortable. I would like to see an optional mount position. I also feel for my left handed firends. While the knife itself is as ambidextorese as they come, the clip is locked on the right hand side. Either a left handed version or an optional mount position would be wonderful. Fortunatly, Spyderco has claimed to be considering a four position mounting scheme fin an updated version, but only time will tell.
In addition, there is only one adjustment point on the whole knife, and that is the blade pivot. I would like to see the pressure fit pins replaced with liner screws to facilitate adjustment, cleaning and repair, need be. Overall, not a preformance issue, but the makings for a more user friendly package.
I'm also a bit concerned with the lock design. Although it is exceedingly stong, I am worried about the lock type choice itself. It has solid lock up with no blade play, and is rock solid when my hand rides high on the grip. However, when my hand slides down on the grip, the preassure from my hand can force the lock open, possibly resulting in accidental closing. With a blade as heavy and shapr as the Chinook, i see that as a real concern for those using it in either hard working conditions, or, in the worse case scenarion, in a defensive situation.
While being of good size, with great materials, I am not convinced this knife would be a good choice for those with smaller hands that may be holding the knife over the lock, or those who would submit it to harsh and depaning use, again due to lock issues. A great look and overall feel, but i would stongly suggest the lock either be redesigned or replaced with a more abuse friendly design.
