Hi Gress.
Great post! As to where a CRK might fit into your collection I cant comment but would like to give you my reason as to why I ended up with a Small Regular as my first high end knife.
I decided to go with it for a few main reasons, versatility was the biggest.
I wanted a elegant, simple, yet a knife that will last me a life time in my use. I ended up with pulling the trigger on the Seb. It has seen work on the farm, work in a bar, on field trips to our Kalahari, West coast and was my dress knife that I clipped into my suite when I went to weddings. Matched the grey inner part of the jacket perfect.
I was/am still in love with that knife until I had to depart with it (beyond my control), but it made such an everlasting impression that even when I have a Insingo, Bone Collector on the way and interested in some customs, that knife just screams my name. I will go to the ends of the world to get another one when I have the funds. But until then I have to be content with what I have.
