I have a more detailed post on my knife builds thread, but just wanted to add the CBKs I finished a couple of weeks ago. I made 2 very similar knives. One is based on the Cold Steel copy of the CBK, plus other based on the original.
In my opinion the one area for improvement on the original is the handles. They are mass produced slabs with minimal shaping, so I made mine with a much more rounded handle and a palm swell. But otherwise they are pretty authentic to the original.
Both are 2.5mm Nitro V stainless. The blade is 4 inches with a full flat grind. One set of handles is black micarta with G10 liners and the other is camo G10 with G10liners.
