CRK will NOT engrave a CGG on an existing scale. Even though it would just be silver reverse contrast. I had asked awhile back for even a reverse contrade Native American and it was a no go...............I did at one time want a particular CGG pattern on an insingo. Since the insingo is only available in plain ( now micarta and G10 are available ), I could not get the CGG on an insingo. Heather told me I could buy just the CGG scale and then a plain insingo and just swap the scale. Its possible their policy has changed since then, but I doubt it. This was about 2 years ago............It basically comes down to if you want a particular CGG, you just gotta buy the whole knife, other wise its going to cost you lots more. I have always been into the CGG/UG CRK's, so I have asked them tons of questions about them and would could be done and what could not be done.
