I originally wonder the same, if a CS version would be offered. And I am still wondering.
On the other side of the coin, it does appear that CASE is releasing more patterns with the Carbon Steel option than in previous years.
And, then it has been mentioned in a SMKW you tube video with a CASE rep, they are introducing different handle materials and color combos, BUT, only in restricted quantities. When gone, they will be GONE.
Like the SMKW exclusive, SEA DRAGON BONE. NOTE, CASE labels the box as Burnt Caribbean Blue Jig Bone. Pretty much all patterns in this color are gone.
It is my take, marketing toward collectors AND SECONDARY RESELLERS by limiting quantity to increase inventory turnover.
A model other knife makers have been enjoying the past several years, as GEC, and the sub brands.
