I think its as much a BK 2 as it can be to be a folder and size wise still be a little practical, 3/16th is still the thickest blade on a folder I have ever heard of. 1/4" is just not very doable if you ever wanna carry the thing in your pocket and not have it pull your pants down. Being a folder the blade can't be longer than the handle it has to be a little smaller unlike the BK2. Of course the thong hole would be an issue, it could have been there but not be functional so why bother. The rest is just cuz I prefer it and this is my first custom folder so I wanted the things I have seen on other custom folders, titanium hardware anodized blue, fileworked liners, and a blade that wasn't mirror shiny ( a trait pretty much all my knives share )
As to the rest, my BK2 doesn't have black grivory handles or screws and the blade isn't black anymore either, it has custom black micarta handles, SS pins and the whole thing is beadblasted. So actually this folder bears more resemblance to my idea of a perfect BK2 than what the original from the factory is.
Here is a shots sans scales and you can see it be a pretty good resemblance to a BK2 also a shot of my customized BK2
