Question about the Chinook Series

[blackmist]

Hello..

I think my next spydie is gonna be a Chinook, my local shop has one but I don't know if it is a I, II, or III.. I'm not even sure there is a III, is there?

Anyway, how can I tell the difference between them, the one I looked at had no numbers on it but it is a Golden CO blade.

Thanks in advance.

Off the top of my head, i think the Chinook 3 is the only one out of the three that is flat ground. (?)

The current Chinook started out being called the II Flatground, it has now been changed to the Chinook 3 designation. As far as I know, that is the only difference between the II and the III.
The Chinook I has a more bowie shaped blade with a pronounced swedge from the tip to about a third of the way down the spine, with a different handle shape. It is also noticably heavier.

Hope this helps :D

also, the II and 3 have at least two way clip screw holes drilled and tapped in the handle. I believe the 1 was only a right hand, tip down knife

Chinook III courtesy of Cliff Stamp...notice it is the only flat ground Chinook


Chinook II; notice it is a hollow grind, S30V, and the spine and blade are different from the Chinook I


The original Chinook...most of these are CPM-440V and they are tip down carry only

[mikebandw186]

and now that we have pictures (thanks Zac), we can now see the differences more easily,

the clip on the I is the military, triangular style, and slightly curved
the blade is thicker, with less curve under the spine jimping
the spine swedge is much more defined
it has pinned construction, and the pivot screw is located on the back
the lanyard hole is much higher up

and on the 3: no spanish notch because of the flat grind and the signature is located on the back of the blade

Not my post, but very helpful info. I have always wondered about the differences myself. I have never handled the Chinook's, but they always make me drool. Thanks for the pics Zac. A picture is worth 1000 words!!

Blackmist, here you have a side by side picture of my Chinooks.

Above the Chinook I and below the Chinook II (the steel marking is not the difference, as Chinook I was available with CPM 440 V and CPM S30; all Chinook II and III have CPM S30V and the handles of them are srew construction and they have a four-way-clip)

Thanks, I think I've been handling a III but now I'll know for sure when I go back up to the shop.
