Anyways.. a day or so ago I was looking at a knife review on YT, and the reviewer pulls up a AFCK for comparison and I was instantly intrigued. Now I don't even remember what knife he reviewed in the first place

Beyond the first eye-catching qualities e.g. round opening hole, appealing design lines and no axis lock (early versions), it gets even more interesting as soon as you look into it a little bit and realize how intertwined Spyderco is in the story of this knife.
Now I'm not sure it's true that the designer, Chris Caracci went to Spyderco with his idea first, but it seems to at least be very well established that the inspiration for his design was the Spyderco Police. And he came up with a slightly modified Police, mainly to make it with a liner lock and an edge that goes all the way back to the handle. Changes that he felt would make it more suitable for his military application as a Navy seal.
Spyderco, apparently wasn't too enthusiastic (at this point), but he was able to convince Benchmade. Who in turn had to get a licensing agreement with Spyderco to use the round opening hole that was such a critical feature of the knife Chris wanted.
It's also interesting that not long after Chris Caracci got Benchmade to make his ideal, militarized version of the Spyderco Police, Spyderco releases a new model which incorporates some of the same ideas - and calls it the Military Model.
This is a very uninformed summary of the info I've stumbled across in the few waking hours I've known about the AFCK. It should not be considered as fact, just inspiration for more research.
And my reason for making this thread is exactly to see if there are some better informed people on this forum. For a knife (AFCK) that seems to have a very loyal following and collectors status, it's surpringly hard to find in-depth historical information as it relates to generations and different versions.
I'm not a regular user of BladeForums, but I tried reviving and old thread about the AFCK, and ask around, but it's not getting any traction. Given the close ties this model has to Spyderco, I'm hoping that there could be some knowledge and interest in the model on this forum.
